UPDATE: Zachary Reyna's body arrived in San Antonio on Friday A plate benefit was held in his honor on Saturday ---------------------------------------------------------------------------------- SAN ANTONIO - A local family grieving the loss of a five-year-old boy killed in a car crash in Mexico over the weekend is now struggling to bring his remains back home to San Antonio died Sunday morning in a rollover crash involving an 18-wheeler in Matehuala about halfway between Monterrey and San Luis Potosi He'd been riding in a car with his seven-year-old brother and grandparents on their way back from a church convention in Mexico who was set to start Kindergarten at Collier Elementary next week His brother and grandparents survived the crash which remains under investigation by Mexican authorities With the full extent of the wreck not fully known to those back in San Antonio at the time Zachary's mother Julie hopped in a car and headed for Mexico with relatives as soon as she learned what had happened providing family and friends with updates from the road "And that's when she told me that Zachary passed away," said Julie's sister Jennifer Navarro Julie was also in contact with her boss Lupe Camacho at Medico M.D. where she works as the lead dental assistant "I was sitting at home and when I heard the message my body just went numb," recalled Camacaho Zachary’s body was eventually moved from Matehuala to Monterrey The question then became how to get Zachary back to San Antonio But going through all the procedures of dealing with the death of a child in another country has proven quite complicated having to translate the birth certificate," explained Camacho we need to have a home here for Zachary to come home to So that's a process that Jennifer and ourselves are trying to help with so that way Monterrey can start the process to get him home." "We're having to find two funeral homes," added Navarro "One in Monterrey to receive the body there because we have to have one here before we can bring the body over." The family has now made contact with a funeral home in each country they're working with Mission Park Funeral Chapel and Cemeteries on SE Military Dr "Where he's going to be laid to rest is called Babyland," explained Camacho "It’s where all the children are laid to rest." and the majority of it needs to be paid upfront "From finding a funeral home in Monterrey to the transportation to receiving him here," said Camacho When exactly Zachary will get here to San Antonio remains unclear we do not know for sure," said Navarro "It’s just the process of everything is taking so long." Camacho and others are doing what they can to help and make the experience less stressful and overwhelming for Julie They’ve set up GoFundMe pages, which you can visit here and hereto donate. Camacho and the rest of the staff at Medico M.D. are also planning a BBQ Chicken Benefit for the Reyna family this Saturday, Aug. 10 in front of their location at 803 SW Military Dr. starting at 11 a.m. "She has a lot of support," said Navarro.

Volume 9 - 2022 | https://doi.org/10.3389/fmats.2022.906851 This article is part of the Research TopicCreative digital design and manufacturing in medicineView all 7 articles cases requiring endotracheal intubation have increased to support breathing through mechanical ventilation; this procedure is necessary when a patient cannot breathe on their own due to respiratory failure it is possible to injure the patient due to poor visibility at intubation some video-laryngoscopes present many advantages lowering the number of attempts to secure the airway and the image’s quality and easy recognition of laryngeal structures this type of device is not accessible to many health institutions due to the price this study proposes the design of a video-laryngoscope in the Computer-Aided-Design (CAD) software and constructed by additive manufacturing the identification of the needs of the medical personnel in the anesthesiology and emergency medicine departments from the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán (INCMNSZ) was taken into account The design specifications provided by the users were used to create a proposal solution at the conceptual design level The material and camera for the prototype instrumentation are presented with the model’s geometric parameters virtual modeling of the device was carried out and rapid prototypes were built to validate the performance of the design proposal The final device was constructed by Selective Laser Sintering (SLS) using Nylon 12 as a construction material the device was evaluated using airway simulators with the support of medical specialists to determine its functionality FIGURE 1. Endotracheal intubation process: (A) placement of the laryngoscope over the patient’s epiglottis and (B) insertion of the endotracheal tube into the patient’s glottis (Schächter, 2019) FIGURE 2. Example of the patient’s position to align the oral, pharyngeal, and laryngeal axes to perform endotracheal intubation (Coloma, 2017) Despite being very useful devices, their main limitation in institutions with limited resources is their cost (∼ USD $20,000.00) (Agro et al., 2003) As an example of the high prices of devices C-MAC #3 is ∼ USD $16,000.00 C-MAC #4 have a price of ∼ USD $16,500.00 With the following general characteristics we just include one disposable blade and a monitor of 7” the King Vision is an economical video-laryngoscope with a price of ∼ USD $ 2,500.00 as its main characteristics are a 4.0” monitor and a single disposable blade the development of a device with the appropriate characteristics that assist the EI procedure and facilitate the management of the DA is needed the device must help reduce the spread of COVID-19 to health personnel Three-dimensional (3D) printed models enable physicians and engineers to consider ergonomic concerns and design alternatives without compromising the price and quality in a timely and cost-effective manner information about the application of 3D printing in anesthesiology or emergency medicine is sparse This work proposes the development of a low-cost video-laryngoscope device due to the need during the pandemic since there was a shortage of this type of equipment in Mexico and the available devices required the specialist doctor to place his face close to the mouth to perform the intubation procedure The main contribution of the presented device lies in the integration of a low-cost high-resolution screen and the design of a tip for the laryngoscope blade whose measurement turns out to be the average between MAC 3 and MAC 4 which are the most used blades for performing emergency intubations in Mexico the device has a fastening system that seeks to improve the device’s ergonomics during the process mentioned above; this last part was added in the conclusion of the manuscript The design proposal called VidLa-SZ was based on the measurement of three video-laryngoscopes: Welch Allyn with Macintosh No each of the device positive and negative characteristics was analyzed The main measurements were as follows: handle (length the requirements and specifications of the specialists in the Anesthesiology and Emergency Medicine Departments of the INCMNSZ were taken into account which are areas that constantly perform the EI process The characteristics and observations that medical specialists consider an ideal video-laryngoscope should provide are a rechargeable battery Once the most important characteristics were determined and the electronic components (camera and screen) were selected The final design considered a device with a 5.5-mm diameter camera with LED light and a 4.5-inch screen to visualize the glottis the length and curvature of the blade and the shape of the handle were considered According to the characteristics desired by the medical specialists the parameters to consider for the design of the 3D model are as follows: • Handle length: The length of the handle should be between 6 and 10 cm to allow adequate grip to prevent it from getting in the way when performing an EI procedure in patients with obesity and/or dense breasts • The shape of the handle: Avoiding a quadratic handle since it can hurt the health worker’s hand when using the device resulting in not exerting adequate force to carry out the EI process It is recommended that the shape be cylindrical or round with at least 3 cm diameter • Blade length: The traditional Mac No 3 blade is considered the most widely used for EI processes within the INCMNSZ 4 blade is also widely used for this process the ideally designed blade is slightly longer than Mac No • Blade angle: The proposed blade angle is based on the Mac No modifying the angle of the tip to raise the glottis and obtain a greater field of vision • Camera position: The camera angle must be tilted toward the blade’s tip to view it • Spatula (purple): The side of the blade is in contact with the tongue while performing the laryngoscopy • Tip (yellow): This is the distal portion of the blade placed in the vallecula to raise the epiglottis • Guide (green): The opposite face of the spatula serves to direct the endotracheal tube • Flange (blue): Its function is to maintain the opening distance for the endotracheal tube to pass • Camera cavity (orange): Space where the camera is placed to achieve an adequate glottic view • Camera channel (strong blue): Channel where the camera slides and the camera cable are stored VidLa-SZ video-laryngoscope design proposal The model with which the simulation was carried out for the static analysis was considered a solid and its volumetric characteristics were: mass (0.123,403 Kg) the following assumptions were considered: • Due to the difficulty of obtaining continuous force measurements during laryngoscopy, the maximal force obtained in the studies cited above (Russell et al., 2012; Cordovani et al., 2019) is used and is considered static since the time of study of interest is when the maximum force is applied (during EI) • The force is applied to the two distal quarters of the spatula with a total magnitude of 21 N, as this was the largest value recorded in the force study using the GlideScope video-laryngoscope (Cordovani et al., 2019) • Loads are applied gradually until they reach full magnitude and remain constant without varying over time allowing inertial forces due to insignificant accelerations to be ignored • The relationship between the applied loads and the model response is linear; if the magnitude of the loads is doubled It is assumed that the boundary conditions are constant and should not vary in magnitude and distribution while the model is deformed • The analysis is performed on the part of the blade and the handle Not including the screen support because the area of interest for the analysis is the blade The force exerted to hold the tongue and elevate the epiglottis during the laryngoscopy process is applied to the blade • Loads applied to the handle are considered clamp loads The static analysis begins with the assignment of the model’s material of construction The material selected for the simulation was PLA the model is subjected to loads and restrictions during laryngoscopy only two types of loads are considered: clamping applied to the handle and normal force applied to the spatula of the blade This is because the handle is where the medical specialist holds the device and must be held firmly to support the tongue and elevate the epiglottis the displacements at the moment in which the maximum force is applied can be considered zero Then the applied load can be considered as a fixed geometry fixture which corresponds to the area of the three selected faces shown in blue where the normal force indicated in orange is applied Normal forces (orange) applied to the spatula of the blade (blue) the software sections the model into small elements connected at common points called nodes to form a network of interconnected discrete elements known as a mesh The number of nodes and elements depends on the model’s geometry Simulation estimates the size of the elements that make up the mesh considering the volume surface area the mesh was made with solid tetrahedral elements of the parabolic type or also known as second-order or higher-order elements These elements are defined by six central nodes This node type was chosen because curved contours have higher precision and produce better mathematical approximations although they consume more computational resources than linear solid elements Another parameter to determine the quality of the mesh is the aspect ratio the tetrahedral elements have the same edge length; however the mesh cannot have perfect elements for many geometries such as the size of an element’s edges The aspect ratio measures the tetrahedral element’s longest and shortest edge It is sought that the value of the coefficient is close to 1.0 Figure 6 graphically shows the aspect ratio with a color scale In blue are the elements with a coefficient of 1.0 while the elements with a coefficient greater than 10 are red showing that few elements do not fit properly The first aspect of analysis is the displacements suffered by the model after applying the force on the spatula at the blade’s tip. The URES scale is used to allow displacements to be detailed on a color scale where blue means null displacements and red maximum displacements. Figure 7 details the displacements that the VidLa-SZ design proposal underwent Displacements decrease proximal to the blade The largest displacements are located at the peak of the prototype (2,102 mm of displacement) due to the force exerted when performing the laryngoscopy process it decreases in the area of camera cavity with a magnitude of 0.8–1.4 mm of displacement the displacements range from 0.350 to 0.526 mm in the handle and the proximal quarter of the blade the displacements are minimal with a scale of 0–0.175 mm Displacement of the VidLa-SZ video-laryngoscope This refers to the rate of length change concerning the original length being a dimensionless quantity. As in the previous analysis, this deformation is denoted by a color scale, where the minimum is 0.001 (blue color) and the maximum value is 0.003 (red color). Figure 8 shows the deformations caused in the study there are deformations with a value of 0.002 as in the proximal area of the spatula (green color) Most of the model has deformations close to 0 the design’s deformations are small; however the junction of the guide with the proximal portion of the flange indicates that it is the area with the greatest deformation in the design This deformation does not significantly affect the VidLa-SZ design proposal it is observed that in the proximal part of the flange the model is subjected to stresses of the order of 5–9 MPa indicated in green it has values close to 2–4 MPa One of the areas of interest for the static analysis study is the force exerted on the tip of the video-laryngoscope, as shown in Figure 10 This figure shows that most of the tip of the video-laryngoscope has a magnitude of 1–3 MPa and the portion where the greatest stress accumulates is in the distal part of the flange (near the camera cavity) with values close to 4–7 MPa The SolidWorks Simulation Tool® allows you to assess design safety using safety factor (SF) criteria. After executing the static analysis, the SF can be evaluated at each node, and the SF is plotted throughout the model, as shown in Figure 11 an SF value less than 1.0 means that the material has failed in that area; if it is equal to 1.0 it means that the material is in good condition and safe which corresponds to the zone where maximum deformation and maximum tension are found showing that although it is the area with the greatest risk it does not represent a problem for the design since the SF has a value greater than 1.0 One of the areas of interest for the simulation is the tip of the video-laryngoscope since it is the element that must withstand the pressure exerted on the vallecula to elevate the epiglottis during EI. Figure 12 shows that most of the tip has an SF greater than 10 (blue) a green stripe with an approximate SF of 6 is perceived located on the flange in front of the cavity where the camera is located the SF has an acceptable value to ensure the resistance of the design and safety factor) showed that the geometry of the design proposed for the construction of the video-laryngoscope is safe since it resists the forces applied to the spatula of the device it is necessary to create rapid prototypes that allow resistance and viability to be verified and evaluate its functionality with the help of medical personnel some of the mechanical properties of Nylon 12 are mentioned preserving its dimensions and mechanical properties The VidLa-SZ prototype was manufactured directly by 3D SYSTEMS to ensure a better fabrication quality aiming to carry out sterilization tests on the material and future tests on patients. The 3D printed model parts include the display screen support and handle with blade fused into one piece, as shown in Figure 13 the medical specialists evaluated the 3D printed device This evaluation was performed using upper airway simulators available at the CEDDEM of the INCMNSZ Photograph of the VidLa-SZ model made of white Nylon 12 The instrumentation of the VidLa-SZ model consists of placing the camera inside the cavity located in the distal part of the blade it is only allowed to place cameras of 5.5 mm in diameter The camera cable is placed inside the channel on the side of the blade tab It passes through the circular hole and the handle and support for the display screen The cable exits through the top of the support for the display screen and connects to the 4.5-inch screen The final integration cost of the proposed video-laryngoscope is ∼ USD $400.00 This price includes the acquisition of the 4.5-inch screen Design validation was the most important evaluation for the design process of the VidLa-SZ since it is an indicator of the performance that it will have to carry out the EI in tests with patients rapid tests of the prototypes made with ABS and PLActive were carried out to refine the angle of the camera and length of the blade The measurements mentioned above were validated and adjusted by using prototypes of the VidLa-SZ video-laryngoscope Those were brought in for testing with a simulator of the upper airway The tests were performed by a resident physician from the anesthesiology service of the INCMNSZ who has extensive experience in the use of video-laryngoscopes The purpose of the tests was to determine the appropriate measurements of the design. The curvature of the proposed blade was evaluated, and the appropriate angle of view was determined to observe the entrance of the glottis. Figure 14 shows the tests carried out with the prototypes identifying achieving an adequate length of the blade and good camera inclination It was considered that the VidLa-SZ will show adequate vision according to the Cormack–Lehane classification and will have good properties resisting the endotracheal intubation process the same device evaluation was carried out in the upper airway simulator Test in the upper airway simulator with the VidLa-SZ video-laryngoscope: (A) vision of the entrance of the glottis and (B) insertion of the endotracheal tube The epiglottis and the entrance of the glottis can be observed the epiglottis does not rise to free the glottic view When performing the procedure on a patient placing the video-laryngoscope over the vallecula causes the epiglottis to rise allowing the inlet of the glottis to be seen Despite this limitation with the simulator the camera position was estimated so that the tip of the model could be observed in the camera view This indicated that physicians could more easily locate within the oral cavity and place the video-laryngoscope in the corresponding position to perform a rapid EI applying lidocaine to the tube and the simulator helped the tube slide easily which was reflected in a decrease in intubation times after the third iteration the tubes tend to slide easily since the anatomical structures are naturally lubricated although adding lidocaine to the endotracheal tube is common Expectations were met regarding the anesthesiology resident’s experience using the device with the simulator The angle of the blade allowed the tube to be placed easily it had to be used as a bougie as a guide to give the blade’s curve to the endotracheal tube The shape of the handle allowed the device to be held firmly and comfortably allowing minimal effort compared to a traditional laryngoscope the image quality is comparable to that of high-end video-laryngoscopes The development of devices that allow assisting in the endotracheal intubation of patients who require life support through mechanical ventilation is an area that faces challenges derived from the anatomical variations of patients with DA The devices available today present solutions that although they fulfil their function still leave gaps in the experience of the specialists who perform the EI procedure The results generated in this work presented a design process building an integral prototype through additive manufacturing of a video-laryngoscope proposal that allows assisting medical specialists in the EI procedure The pandemic caused by the SARS-CoV-2 virus created a shortage of this type of device in hospital units to care for infected patients and protect health personnel The VidLa-SZ video-laryngoscope is designed to assist in the EI of adult patients who can be intubated with the Macintosh No and sterilizable device with good image quality and resistance to the efforts at the time of carrying out an EI The design process made it possible to identify the needs and align the parameters of the concepts with the most important requirements for medical specialists who perform EI Greater importance was given to the essential criteria for them which allowed for evaluating the concepts and selecting the materials and the electronic components for device construction The static analysis of the model determined the behavior of the proposed geometry when subjected to the loads reported in the literature in force studies during laryngoscopy demonstrating that the design can avoid great displacements or stresses which can affect the structural integrity during the operation of the device due to the safety factor of 3.375 The construction of the device through additive manufacturing by FDM using ABS and PLActive as materials allowed rapid prototypes to validate the design in conjunction with medical specialists in the area of anesthesiology and emergency medicine of INCMNSZ The device’s construction using SLS using Nylon 12 was the best option for accessibility This price includes acquiring the 4.5-inch screen When compared to video-laryngoscopes available on the market it becomes an affordable option for low-resource healthcare units The instrumentation of the device with the 5.5-mm diameter Teslong endoscopic camera and the 4.5-inch screen was easy to assemble and guaranteed a clear The evaluation of the device using the upper airway simulator available at the CEDDEM of the INCMNSZ with the medical specialists confirmed that the proposed angle and the position of the camera facilitate insertion of the endotracheal tube using a bougie as a guide in addition to providing a high-quality image and a comfortable and firm grip for the doctor reducing the effort compared to a traditional laryngoscope The original contributions presented in the study are included in the article/Supplementary Material further inquiries can be directed to the corresponding author JB: critical

The boots first appeared in the rural town of Matehuala with people simply altering their boots to make them pointier Then people from neighboring towns started to compete on pointiness "Then people started making them pointier and pointer until it got out of control," says one young man who fashions pointy boots out of water hoses The trend coincided with the rise of tribal (pronounced tree-BAL) music Residents of Matehuala started wearing the boots in tribal dancing competitions at clubs The boots eventually made their way to Hispanic neighborhoods in Texas. Even though the boots originated in Matehuala, Erick Rincon, a DJ who skyrocketed the boots' popularity when he featured them in a music video that's been viewed more than 50 million times on YouTube told Vice they're actually more popular in Texas While I'm watching "Toy Story"... Hahaha! A photo posted by NѧԀıѧ ʟєѧʟ (@nadialeald) on Aug 22 The boots are still beloved by tribal fans and tribal dance crews take a "haters gonna hate" attitude "It's all about how you feel inside," says one man at the end of the documentary wearing boots that curl into a little ball like an elf boot Overall, the trend is yet another example of how fluid music culture can be between Mexico and the U.S., like when emo music, which has its roots in D.C., became incredibly popular in Mexico, or why narcocorridos Who knows if these incredibly impractical boots will make it to the U.S. mainstream in the way that "chola culture" was appropriated by Rihanna and Selena Gomez these boots have already made it across the pond A previous version of this story incorrectly referred to boots having 21-foot-long toes Become an NPR sponsor the scene of recent bloody turf battles between the Gulf drug cartel and the Zetas gang Nuevo Leon state security spokesman Jorge Domene said a ninth person died when he apparently fell trying to flee the attackers across rooftops The attack happened on Monday evening at the Matehuala Men's Club Domene said some of the victims were bar employees Authorities are investigating motives behind the attack but say a recent upsurge in violence is a result of fighting between the Zetas and the Gulf cartels the Mexican army reported clashes that left four gunmen dead The army said armed men attacked a patrol in the town centre of Reynosa Presumed allies of the gunmen set up roadblocks throughout the city in order to stop army units moving freely The military did not release the identities of any of the dead Majority of migrants rescued in Matehuala were from Central and South America and included 34 children Authorities have found 123 people from Central and South America trapped in a trailer in the central Mexican state of San Luis Potosí, the country’s immigration agency said on Thursday. Officials from the state attorney general’s office found the people in Matehuala, a city on the border of Nuevo Leon, on Wednesday after a local reported hearing cries for help from a locked trailer box. Read moreThe majority rescued were from the Central American nations of Guatemala, Nicaragua, Honduras and El Salvador, as well as four from Ecuador and one from Cuba, according to Mexico’s National Immigration Institute. Among them were 34 children. The immigration agency did not say how they came to be stuck there nor where they were heading, but such groups of migrants typically hope to reach the United States. The same day police in Ciudad Juárez, across the border from El Paso, Texas, arrested three alleged human smugglers after finding 11 Guatemalan people trapped in a house, according to the Chihuahua state security department. Chihuahua’s attorney general has opened an investigation into the suspects, two of whom are 16 years old.

The fact that fashion firms find inspiration in the most unsuspected places or objects is nothing new. Neither is the adoption or “appropriation” of elements, whether pertaining to folklore or created by a region or community. The latest to see one of their own designs become a trend, no more and no less than on the Paris Fashion Week runway, are the inhabitants of Matehuala (Mexico).   It took about five years for them to travel through the ‘distance” separating Matehuala from Paris Fashion Week, making a stop on a David Gueta video clip –the ‘pointy boots” or ‘Guarachero boots’ appeared on the French DJ’s ‘Play Hard’ video--. It had only been a few months since its ‘fashion’ baptism, when Commes des Garçons was turning them into the star footwear of their 2015 Spring-Summer Men’s Collection.  The boots that caught practically all the attention of the company’s fashion show are already available for a price that is, however, not suitable for all wallets: some US$515 for a pair on the Ssense.com website.  The ‘Guarachero boots” may be revolutionizing the narrow Paris catwalk, but in Matehuala they are far from being a novelty. There the boots have been customized simply by color, glitter or different materials. Will the Guarachero boots return this spring? Only the streets of the world will tell. THE BEST OF THE AMERICAN MULTICULTURAL EXPERIENCE Volume 2 - 2022 | https://doi.org/10.3389/fsoil.2022.1041377 and biological activities has resulted in potentially toxic metal pollution of the soil all over the world This has caused degradation of soil quality two study sites were selected to evaluate metal concentrations in the agricultural as well as the recreational soil around the Cerrito Blanco in Matehuala and Fe were analysed in order to determine the level of contamination risk as well as their spatial distributions this study is mainly focused on toxic metals The contamination indices techniques were used to evaluate the risk assessment of soil the positive matrix factorization (PMF) model as well as the geostatistical analysis was used to identify the contamination sources based on 64 surface soil samples After implementing PMF to analyze the soils it was possible to differentiate the variations in factors linked to the contaminants The soil in the two studied locations included high concentrations of As including variations in their spatial compositions which were caused by direct mining activities the movement and deposition of smelting waste and the extensive use of irrigated contaminated groundwater for irrigation The four possible factors were identified for soil pollution including industrial and naturogenic based on the PMF and geostatistical analysis The spatial distribution of metal concentrations in the soil was also presented using a geographical information system (GIS) interpolation technique The identification of metal sources and contamination risk mapping presents a significant role in minimizing pollution sources and it may be performed in regions with high levels of soil contamination risk quantitative evaluations of the properties and origins of heavy metals in soil are essential for public safety metal contamination in soils might be a prominent indication of the influence of anthropogenic activities it is relevant to evaluate the variation of uncertainty in PMF models these heavy metals were not repeated for this study The other reasons for choosing these metals found in this same region are because of historic mining activities and the data availability Figure 1 Study area map showing metal concentrated soil sampling locations of (A) recreational soil and (B) agricultural soil Figure 2 Flowchart illustrating the methodology of this study The geo-accumulation index (Igeo) has been widely used as a biogeochemical criterion to assess the contamination level of a specific metal in environmental soil or sediments since 1969 (44, 79). This index (Igeo) was developed by Muller (80) to determine the contamination level of toxic metal concentration in soil by comparing the total metal components measured to its reference level or background value of concentrations To assess the level of metal pollution in the soil Igeo is calculated using the following equation: Where, Cn is the observed metal concentration in the soil sample (mg/kg), Bn indicates the background reference value for n metal in the soil (mg/kg), and the constant factor 1.5 was used to adjust the background matrix for any differences induced by lithospheric influences (44). Table 1 shows the seven different classifications of Igeo according to the contamination levels Table 1 Contamination indices based on the classification of soil The contamination factor (Cf) is determined using the following equation: Where, Cm denotes the observed metal concentration in the soil sample and Cb is the background reference level concentration of the selected metal. The contamination factor (Cf) is divided into seven classes, as indicated in Table 1 The modified degree of contamination (mCd) is the ratio of the sum of the contamination factor of each selected metal to the total number of measured metals in the soil, which is used to calculate the absolute degree of contamination in a specific soil sample (88). The mCd computation includes the inherent characteristic of providing an average total value for a variety of contaminants (89) The following equation is a modified generalised approach to calculating the degree of contamination: Where, Cf refers to the contamination factor, i is the i th metal or selected specific metal in the soil sample, and the total number of metals in the soil sample is denoted by n . The modified degree of contamination (mCd) is divided into seven different classes, as indicated in Table 1 The Nemerow Pollution Index (PIN) is a technique for measuring the comprehensive level of contamination in the surface soil based on contamination factors, and it comprises metal concentration assessments (19, 85, 90). This approach may offer a logical explanation of the heavy metal contamination at each site in its entirety because many contaminants can affect a specific site (91) The following equation is used to compute PIN: Where, Cfmax is the highest contamination factor value of each metal in the soil samples and Cfaverage is the average contamination factor value of all the collected soil samples for each specific metal. The five different classes of metal contamination in soil are shown in Table 1 based on PIN values The purpose of this model is to factorise the initial matrix X (i x j) into two-factor computational matrices F (k x j) and G (i x k) and an additional residual matrix E (i x j) The fundamental PMF formula is as follows: Where Uij denotes the uncertainty in the jth metal for the ith sample The data regarding concentration and uncertainty are necessary for the PMF model The uncertainty in the Method Detection Limit (MDL) of a specific metal uses its concentration and specified error fraction If the MDL value is exceeded by the metal concentration the following formula can be used to determine the uncertainty: σ denotes the relative standard deviation of each metal or error fraction and c represents the concentration of metals the uncertainty is calculated using the following equation: The value of the method detection limit (MDL) is calculated as follows (95): t(n=1, 1−∝=0.99) represents the Student’s t-value appropriate for a single-tailed 99th percentile t statistic and a standard deviation estimate with n-1 degrees of freedom and Ss is the sample standard deviation of the replicate spiked sample analyses and Fe were higher than the reference values in the recreational soil by approximately 5.43 for the agricultural soil by approximately 3.50 Compared with the permissible limit values defined by the various researchers for soils the mean concentrations of heavy metals like As and Fe were all higher than the severe risk screening levels revealing that the soil poses a health risk for agricultural and recreational uses there was more variation and spatial dispersion in the concentration of metals in the recreational soil of the study region than in agricultural soil and it is expected that anthropogenic activities have an impact on this concentration Table 2 Descriptive statistics of metal concentrations for soil physicochemical properties point source contamination can be inferred from the concentrations of As which were spatially distributed as being relatively high The highly contaminated areas containing Ca and Fe were found in the south-western part of the recreational soil study area and the high-value areas of all metals were quite extensive The distribution pattern of metals in agricultural soil was clear through spatial analysis the agricultural soil contained higher levels of Ca with the highest values located in the northern to southern parts of this area Mg in the agricultural soil was mainly in the south and south-eastern parts of the study area The areas with the highest As and Sr values were alongside narrow roads and the waterbody and were mostly in the north-western part As and Sr had comparable spatial variation features The As concentration hotspots in both study areas were mainly associated with irrigated groundwater and past mining activities The significantly related distinction of the parent material during soil formation and other anthropogenic activities may be the reason for the high concentrations of other metals (except Na) in these regions This indicated that climatic effects like wind and rainfall events may potentially affect the distribution of metals in the area of study Since the climatic environment in the study areas is semi-arid having limited precipitation irrigated cultivation is the preferred mode of agriculture the concentration levels of heavy metals like As it may be stated that the study areas’ climate has some impact on the spatial distribution of metal contaminations the metal distribution in both recreational soils and agricultural soils showed similar distribution patterns the high-value range of all metal concentrations exceeded the permissible limits or the reference values and the cause may be connected to the metallurgic and natural origin of metals Figure 3 Spatial distribution of metal concentrations in the recreational soil Figure 4 Spatial distribution of metal concentrations in the agricultural soil The Igeo analysis was utilised to determine the extent of cumulative concentration of metals in the soil along with the amount of heavy metal contamination. Figure 5 shows the box plot diagram of metal contamination assessment based on Igeo index for both recreational and agricultural soil. The descriptive analysis of contamination risk assessment by different types of contamination indices is shown in Table 3 Figure 5 Box plot of metal contamination assessment based on Geo-accumulation index (Igeo) for (A) recreational soil and (B) agricultural soil Table 3 The metal contamination and risk assessment by different types of contamination indices The mean Igeo index values of metals in recreational soil were arranged in the decreasing order of Ca (4.69)> Na (3.83)> Mg (3.61)> Fe (2.94)> K (2.82)> As (1.33)> Sr (0.65)> Mn (0.05) while the mean Igeo values of metals in the agricultural soil were in the following increasing order of Ca (5.27)> Mg (4.97)> Fe (3.93)> Na (3.73)> K (3.57)> Mn (1.10)> As (0.99)> Sr (0.16) The mean Igeovalues of all metals were greater than zero indicating that all metals contributed to pollution in the surface soil in both study areas and more than 90% of the soil samples were at polluted levels and K in the agricultural soil were also more than 3 the study area had high contamination levels of heavy metals like As it can be concluded that As contaminants are at a higher level in recreational soil than in agricultural soil and Fe fluctuate at low to high levels of contamination in both study soils Figure 6 Contamination factor (Cf) percentage of metals for (A) recreational soil and (B) agricultural soil at different contamination level The highly contaminated and precautionary stages were observed in both study areas due to past metalliferous mining and anthropogenic activities it was possible to conclude that the soil in the abandoned metallurgical region had been severely contaminated And the level of pollution is increasing because of natural soil formation the use of contaminated groundwater for irrigation It was suggested that specific environmental restoration should be carried out All of these models generated R2 values of more than 0.7 indicating a significant correlation between selected metals and the utilisation of a sufficient number of factors obtained from the PMF model Figure 7 Factor profiles and source contributions of metal concentrations from PMF for recreational soil Figure 8 Spatial variations for the normalization from each of the four factors within the recreational soil Table 4 Source contribution rates of factors for metal concentrations in the soil Factor 1 was mostly affected by K and Sr with source profiles of 1554.50 mg/kg and 261.30 mg.kg-1, and the contribution rate of 46.1% and 51%, respectively (Table 4) It also contributed 37.2% and 34.3% to Ca and Fe in this factor The areas with high-level factor 1 values were found in minor quantities at scattered locations Soil-Sr concentration is typically considered to be a key factor for the deposition of air dust particles that have interacted with strontium ions from industrial operations and may potentially be exacerbated by human activity The reason behind the increase in K levels in this area were includes the tillage system The higher soil moisture often results in more K being generated factor 1 could mostly be considered to involve natural activities Factor 2 provided an explanation for the high loadings of Mn (53.1%), Fe (53.1%), Mg (43.1%), and K (42.7%) (Table 4). Mn and Fe are widely found at higher acidic levels in soils, increasing alkalinity levels. Metal casting, soil formation by chemical processes, and other industrial activities all have the potential to produce Mg and K in the environment (106) factor 2 possibly reflected past mining and industrialization activity sources the soccer fields are maintained by irrigation using groundwater the contaminated groundwater might be interpreted as factor 3 Factor 4 was mainly contributed by Na with source contribution amount and rate of 1335.20 mg/kg and 94.9%, respectively (Table 4). In the study, Na was the only metal with concentrations below permissible levels. The high-value locations of factor 4 and soil-Na concentration were mainly distributed in the middle of the study area which refers to the soccer pitch (Figure 8) The majority of Na concentration in soil was from pesticides factor 4 may represent anthropogenic activities such as different types of human activities The schematic of the factor profiles and source contributions percentages for various metals in agricultural soil based on PMF results is shown in Figure 9. Table 4 depicts the parameters for the PMF modelling with four factors of sources. The spatial distribution mapping of source contributions determined by the PMF results was assessed using the IDW interpolation technique, shown in Figure 10 Figure 9 Factor profiles and source contributions of metal concentrations from PMF for agricultural soil Figure 10 Spatial variations for the normalization from each of the four factors within the agricultural soil Factor 1 revealed the specific representation of the factor profiles and source contribution of each metal using the PMF model, which shows Mg (51.8%), K (52.7%), Mn (57.6%), and Fe (55.5%) having high factor loadings than the other metals (Table 4). According to the spatial distribution map of factor 1, the high-value locations are clustered around the agricultural land and the south-eastern part (Figure 10) The soils in the study area were severely polluted by heavy metals like Mn and Fe and indicating substantial mining activities and industrialization impacts The soils with high contents of Mg and K in the study area revealed the rapid increase in industrialization activities But it can be stated that a high amount of K is good for the agricultural soil because it is an important component that supports plant growth factor 1 was probably related to mining and industrialization activities The possibilities of a higher amount of potassium levels in the soil include over-fertilization and a large range of rocks and minerals in the study area it might be interpreted that factor 2 is of natural source Factor 3 was mainly contributed by Na, with a source contribution amount of 57.7% (Table 4) Na was the only metal with concentration levels below permissible limits in this study The high amount of sodium salt concentrations in the soil is caused by pesticides and other soil inorganic biofertilizers that are accumulated in the runoff and a water softener in addition to certain uses But the high amount of sodium usage in agricultural soil affects the metabolism of the plants and can cause drought conditions factor 3 was probably related to human incidents due to agricultural activities suggested that by using contaminated water to irrigate agricultural land in Matehuala the content of As in soil has significantly increased it has led to As bioaccumulation in maize crops as well as translocation within plants industrial wastes and sludges may be the most probable factor contributing to the occurrence of As and Sr in the agricultural soil since these are immediately discharged into the water body within the study area factor 4 is identified as the groundwater used for irrigational activities The past mining and industrialization activities were apportioned as having the highest percentage contribution to the recreational soil (29%) and the agricultural soil (39%) other contributing factors were the natural source (28%) and human or anthropogenic activities (18%) the corresponding contributions are natural sources (27%) and human or anthropogenic activities (15%) The source determination of each factor for both types of soil indicated that Ca and K were from soil parent materials while As and Sr could be associated with heavy metal-contaminated sewage irrigation and fertilizer application and Fe were mainly attributable to mining and smelting and waste management during the mine operation But Na was related to natural sources and human incidents such as concentrated runoff of pesticides it is impossible to overlook the fact that mining and industrialization activity had a significant impact on the levels of heavy metals like As Figure 11 Source factorization of (A) recreational soil and (B) agricultural soil Through the use of numerous auxiliary data this study created a unique integrated spatial technique for quantifying source apportionment and defining metal contamination in surface soils in Cerrito Blanco The results of the metal concentrations in soils revealed that the mean concentrations of the selected eight metals in the soil were much higher than their specific permissible limits with the exception of Na The mean concentration levels of heavy metals like As and Fe were higher than their respective permissible limits by around 5.43 The results indicate that natural soil formation and mining activities increased heavy metals in the topsoil The Igeo was higher than zero for all selected metals while the Igeo values of As and Fe were greater than one which indicates that As and Fe were the main heavy metal elements that caused contamination in the recreational soil Mn and Fe were the key heavy metal elements that caused contamination in the agricultural soil The mean value of the modified degree of contamination (mCd) was 11.83 which indicates a very high degree of contamination in recreational soil and which indicates an extreme degree of contamination the PIN values of these two soils are 29.97 and 43.22 which confirms that the area is highly contaminated the four potential source contributions of recreational and agricultural soil for metal concentrations in this study area are natural sources The results of the source-specific risk assessment didn’t reflect the source apportionment factors for the concentration of metals; the order of the contribution of the risk factors in recreational soil was the corresponding contributions are factor 1 (39% a 95.8% loading on factor 3 for contamination in recreational soil and 70.5% loading on factor 4 in agricultural soil due to irrigational groundwater sources contributed primarily to the overall contamination risk and Fe indicated identical spatial distributions with high risk But it can be noted that some of these metals such as Ca and K are not providing a significant risk for soil contamination despite being present in high amounts in soil due to the beneficial role of these metals for soil health The results of this study indicated that past mining activities and metallurgical pollution contributed most significantly to the contamination risk further restrictions on the discharge of wastewater from mining industries could be adopted to reduce contamination risks in soils and contamination risk indices have significant implications for decision-makers to reduce threats to human health and environmental risk from possible sources of pollution The datasets presented in this article are not readily available because they are subjected to funders’ regulations Requests to access the datasets should be directed to the corresponding author All authors contributed to the article and approved the submitted version The project has received funding from the Engineering and Physical Sciences Research Council (EPSRC-IAA) UKRI through the Project 748502: Spreading The Chemical Free Arsenic Removal Technology To Various Communities In India Thanks to the Institute of Infrastructure and Environment The authors are thankful to The School of Energy Edinburgh for providing a student bursary to the first author for doctoral research through the James Watt Scholarship We used Arsenic toxic metal data and GIS shapefile data while working on this study and the data has been published previously in the International Journal of Environmental Research and Public Health MDPI in 2018 and Journal of South American Earth Sciences Elsevier in 2022 for a different type of study on toxic metal contamination References to these studies are cited in the inner text The Supplementary Material for this article can be found online at: https://www.frontiersin.org/articles/10.3389/fsoil.2022.1041377/full#supplementary-material Improved heavy metal mapping and pollution source apportionment in shanghai city soils using auxiliary information Assessment of soil heavy metal pollution using stochastic site indicators CrossRef Full Text | Google Scholar Spatial distribution and source apportionment of heavy metals in soil from a typical county-level city of guangdong province Contamination assessment and source apportionment of heavy metals in agricultural soil through the synthesis of PMF and GeogDetector models Assessment of heavy metal pollution and health risks in the soil-plant-human system in the Yangtze river delta Int J Environ Res Public Health (2017) 14(9):1042 Impacts of geology and land use on magnetic susceptibility and selected heavy metals in surface soils of mashhad plain A new exploration of health risk assessment quantification from sources of soil heavy metals under different land use A review of soil heavy metal pollution from industrial and agricultural regions in China: Pollution and risk assessment Predicting heavy metal contents by applying machine learning approaches and environmental covariates in west of Iran Exploratory and spatial data analysis (EDA–SDA) for determining regional background levels and anomalies of potentially toxic elements in soils from catorce–matehuala 11.
