| Summary: | The present study represents a first insight into the Draa Lasfar min (Marrakech - Morocco) to assess the degree of polymetallic pollution caused by anthropogenic activities (like mine extraction) and consequently the possible diffusion of heavy metals and to predict the risk of their mobility in the surroundings of the mine area. The edaphologic parameters pH and electrical conductivity (EC) were measured according to standard methods whilst heavy metals concentration was atomic absorption spectroscopy (AAS). Contamination factors (CF) and pollution index (IP) were calculated in order to estimate the anthropogenic contribution of target pollutant determining Cd, Cu, Pb, and Zn as the main pollutants in this region. The results showed that the polluted areas at the vicinity of the mine especially two rural communities (Ouled Bou Aicha and Tazakourte) of about 5790 ha are probably linked to increasing mine activities and the lack of appropriate measures to counteract its effects causing a progressive pollution of wate and soil with heavy metal emissions in the region under study |
