“…As the most important economic part of ACED, HIZ is concentrated in many enterprises, including metal processing, metal smelting, and other enterprise types, which may lead to changes in soil heavy metal concentrations. In this study, the concentration of heavy metals in HIZ was generally higher than other industrial land in China [9,11,36], but lower than an industrial zone in Mexico [41] and in India (except for Zn) [12]. Depending on the results of spatial analysis and Nemero evaluation (Figures 4 and 5), although heavy metals in the surface soil of HIZ did not reach pollution levels, the higher heavy metals concentration (except for Ni) in HIZ surface soil were observed, indicating that heavy metals in HIZ surface soil may be affected by relatively intensive anthropogenic activities.…”

“…Many researchers have suggested that anthropogenic activities such as improper disposal of electrical conducts and combustion of fossil fuels as well as industrial activities can release Hg into the environment [11,25,27,41]. The concentration of Pb in soil are associated with anthropogenic activities such as the pharmaceutical, battery manufacturing, and waste incineration [11,39], and the traffic is most possibly the major source for the enrichment of Pb in the soils [35].…”

Anthropogenic activities may result in the accumulation of heavy metals in the soil, especially in economic development zones with frequent industrial activities. Therefore, the investigation and assessment of soil heavy metal pollution in economic development zones is one of the important measures for soil environmental management and sustainable development. This study used Nemero evaluation, Kriging interpolation, cluster analysis, and principal component analysis to investigate the contamination degree, spatial distribution, and origin of heavy metal in Anhui Chaohu Economic Development Zone (ACED), Anhui, East China. The result showed that different land use types can cause different levels and types of soil heavy metal pollution. The maximum concentrations of heavy metals in the study area all exceeded their background value but did not exceed the guide values. The highest average concentrations were found in Zn, followed by Cr and Ni. The concentrations of As in soils have the largest coefficient of variation (CV) at 38%. The concentration of heavy metals in different functional areas was varied, the areas with higher Ni, As, Cd, Zn, and Cr concentrations were mainly distributed in Hot Springs Resort (HSR), the relatively higher concentrations of Pb, Hg, and Cu were mainly distributed in Integrated Zone (IZ), while all heavy metal (except for Ni) have relatively higher content in the surface soil of Huashan Industrial Zone (HIZ). Origin analysis showed that soil As, Cd, and Zn in HSR surface soil were predominantly influenced by agricultural activities, while Ni and Cr were mainly controlled by parent material. Pb and Hg in IZ surface soil were predominantly originated from the vehicle and domestic exhaust, and Cu was mainly controlled by industrial pollutants. Industrial activity was the main source of soil heavy metals in HIZ. Although heavy metal in ACED surface soil did not reach pollution levels, the concentration of Cd, Hg, Pb, and Cu was significantly affected by anthropogenic activities, especially in HIZ, which the necessary attention of heavy metals needs to be given.

“…In one study [73], contamination by heavy metals (Cr, V, Ni, Hg, and Cd) in soils near a thermal power plant at Playas de Rosarito, Baja California was examined. Analyses of metals were performed by GF-AAS; organic matter, pH and texture were also determined in samples from topsoils and depth profiles.…”

“…Analyses of metals were performed by GF-AAS; organic matter, pH and texture were also determined in samples from topsoils and depth profiles. The study's interpretations, including calculations of the Igeo, EF, and statistical analyses indicated that the use of fuel oil at the local thermoelectric plant had contributed to the metals' accumulation in the soils [73]. In one study conducted in Mexico City [74], the spatial distribution of heavy metal concentrations (measured by XRF) in topsoils was defined with a GIS.…”

<p>This review presents environmental geochemistry studies developed in Mexico involving analytical chemistry applied to marine, lake, lagoon, dam, and fluvial sediments, soils, and groundwater over the past 15 years. The paper summarizes the objectives of the research, the analytical methods that were used, the methodologies applied for the interpretation of the results, and the primary findings for the areas and specific substrates that were studied. Although diverse analytical techniques were applied, atomic absorption spectrometry was the primary method of analysis, followed by inductively coupled plasma atomic emission spectroscopy. Studies are widespread in the Mexican territory although some areas are still lacking in information; in addition, most of the country’s contamination problems have yet to be remediated.</p>

“…In Mexico, groundwater supplies 75% of drinking water. Several studies have shown that Mexican aquifers and adjacent soils contain high concentrations of heavy metals (Armienta & Segovia 2008;Maldonado et al 2008;Pastrana-Corral et al 2017;Navarrete-Rodríguez et al 2020). Heavy metals and other hazardous elements are naturally present in the environment as minerals, but human activities release them into the environment.…”

Heavy metal pollution in drinking water is a serious health risk, particularly in developing countries. Membranes of poly(vinyl formal) (PFA) were synthesized to explore their use for heavy metal removal from water samples from the polluted Mexican river ‘Atoyac.’ A single incubation step with PFA membranes for 24 h was sufficient to reduce lead, iron, manganese, arsenic, and thallium concentrations to acceptable levels for drinking water, according to the Mexican standards. PFA showed high adsorption capacities (Qe), even in the presence of multiple metals and low cation concentration. Mass transport phenomena were characterized as a function of the crosslinking degree and pH. To simulate real-life operation conditions, water fluxes across PFA membranes were characterized as a function of their crosslinking degrees and controlled external pressures. PFA membranes allowed fluxes at pressures of up to 2 kg/cm2 with no deformation or breaking. Tensile strength, strain stress, elastic deformation, and Young's modulus were assessed. In contrast with previous reports, no further PFA modifications were required to obtain an excellent adsorption performance, which results in lower production costs. The ease of PFA synthesis and handling, and low production cost make it an ideal material to be applied for remediating the polluted urban water.
