This study reported that the As, Zn, Pb, and Sb concentrations were much higher in abandoned tailings than in active tailings dumps. These values exceeded the BC of the area. The comparison of these concentrations with the ecotoxicological levels proposed by Van den Berg (1993) indicates that As is the element with the highest potential for pollution. In fact, the mean value of 2947.5 mg/kg in the uppermost part of the profile of the old tailing dump represents a potential risk of pollution in the Chadak area.
