| Abstract: | This work aimed to assess the degree of anthropogenic influence and severity of heavy metal from a non-ferrous metal smelting industrial zone. The results suggested that anthropogenic inputs played a dominant role in the enrichment of Cu, Zn, Pb, Sb and Cd. These metals showed similar spatial distribution patterns. Multivariate analysis showed strongly significant relationships between Cu–Zn,Cd–Zn, Cd–Sb, Sb, Sb, Cu, Zn, and Pb. Strong relationship was found between Cr, Ni, Cu, Zn, Sb and organic matter in soil. Risk evaluation results within the soil investigated profile was in the following order: Cd > Sb > Cu > Zn > Pb. Nemerow’s synthetical contamination index revealed that there is substantial ecotoxicological risk among the sampling sites with 8 of 9 of these locations exceeding the Nemerow criteria for seriously impacted sites and another site was close to moderately polluted domain. |
