“…The Soil and Environment software evaluates the environmental soil functions through the analysis of quantitative and semi-quantitative parameters determined in the laboratory and field, respectively [17]. For example, heavy metal sorption is estimated using the following equations [8]:…”

“…The function of sorption of heavy metals by soils is of great importance for urban environments, since it is in cities where human beings agglomerate, and their health can be affected [8,16,42]. The properties of the soils used to assess this environmental function were the pH, organic matter content, and clays, since these have the greatest influence on the sorption of heavy metals [8]. The evaluated soils had intermediate and high scores at a depth of 5 cm, mainly due to their pH values ( Table 3).…”

“…On the other hand, the value of the environmental functions of soils has been recognized in recent years [8][9][10][11], but only qualitative models have been developed for evaluating these functions [12][13][14]. There are a few examples of quantitative models that consider the environmental soil functions, but the complete soil profile has never been included in these evaluations [15][16][17][18][19].…”

“…There are a few examples of quantitative models that consider the environmental soil functions, but the complete soil profile has never been included in these evaluations [15][16][17][18][19]. The first quantitative models for evaluating the environmental soil functions considering the complete soil profile were made by [8,20]. These models were later modified and improved for the development of algorithms [15] and a commercial multiplatform and multilingual software called Soil & Environment [16,17].…”

Making quantitative evaluations of the environmental functions of the soil in a quantitative way is an urgent necessity for transitioning towards the sustainable use of soils. The objective of this work was to use and improve the Soil and Environment software for soils of volcanic areas, for which the software was not designed to work on. The study was conducted in the volcanic area of Michoacan, Mexico. Nine soil profiles were described; samples were taken from each horizon and the physical and chemical properties of each sample were analyzed. The Soil and Environment software was used to conduct pedoecological evaluations of the soil samples and, subsequently, an evaluation of the environmental functions of the soils and the modeling of scenarios was carried out. The soil profiles studied showed variable properties of hydraulic conductivity, field capacity, air capacity, effective cation exchange capacity, and soil organic carbon. The soils showed very high nutrient retention, high naturalness and sorption of heavy metals, and low cultural and natural archive properties. The Soil and Environment software generally works well with soils of volcanic areas; however, we suggest improvements in the evaluation method of the following functions: naturalness and agricultural quality. Additionally, the estimating method of aeration capacity and hydraulic conductivity should be calibrated for the properties of the volcanic soils. The modeling of scenarios allowed us to identify the soil profiles that are most vulnerable to degradation. The modeling of scenarios provided a clear idea of the negative and positive effects that a change in soil use would have.

Heavy metals in street dust represent a risk to the human health due to their toxicity, persistence and bioaccumulation. Using the US Environmental Protection Agency (USEPA) assessment, here, we review the human health risks of such dust worldwide. The street dust in such cities is contaminated by As, Cd, Cr, Cu, Hg, Mn Ni, Pb and Zn beyond the median levels of the world soil background values. Among these elements, the median values of the hazard risk indices (non-carcinogenic risk) are highest for As, Cr and Pb and the median values of the risk indices (carcinogenic risk) for As are in the tolerable risk range for children and adults and in the case of Pb, the median value of the carcinogenic risk indices are also in the tolerable range for children. We emphasize that the level of heavy metals in street dust pose a considerable risk to the human health and require monitoring and approaches to reduce such toxic levels.
