Evaluation of enzyme activities in long-term polluted soils with mine tailing deposits of San Luis Potosi, M,xico

摘要

San Luis Potosi is one of the largest metal producers; mining activity has been responsible for metal emissions for over 100 years, from several sources (deposits, tailings, effluents, and dusts) generating effects in human and ecosystem health. The objective of this study was to evaluate the effect of the concentrations of heavy metals in the soil health of four municipalities of San Luis Potosi contaminated with mine tailings, using enzyme activity as a biochemical endpoint.
