摘要:The abandoned mine of Zaida, located at about 30 km NW of Midelt in the Upper Moulouya (Morocco), was one of the main lead deposits operated between 1972 and 1985. The mining activities in this site generated large amounts of waste stored as tailings pits. The purpose of this study is to assess the total content of heavy metals in soils located around the tailings area and their spatial variation. Forty-two samples were taken from a depth of 20 cm and analysed for Cu, Zn, Cr, Co, Cd, Ni and Pb Using ACP-AES. Results showed that soils in the studied area have medium to low levels compared to normal levels of non-contaminated soil, except near the tailings and the mining center where the recorded levels are relatively high compared to the values of non-contaminated soil taken from the literature and are highly enriched in metallic elements.
