Abstract

Concentrations of 8 heavy metals (Cd, Cr, As, Pb, Zn, Mn, Cu, Ni) in soils from the living quarters of four various administrative districts of Kunming were determined. Pollution levels and ecological & health risk were assessed by index of geo-accumulation (I_geo), the potential ecological risk index (RI) and human health risk assessment in the study. Results showed that all heavy metals except Cr and Ni exceeded their background values. All of the samples’ heavy mental concentrations were lower than the risk screening values for concentration of development land in the national soil environment quality standards(GB 36600—2018). The index of geo-accumulation (I_geo) data showed Zn>Cd>Cu>Mn>Pb>Ni>As>Cr, and the pollution of Zn and Cd reached the moderate levels. Potential ecological risk index (RI) results showed Cd>Ni>Cu>As>Pb>Mn>Cr>Zn, in which Cd had a strong potential ecological risk, indicating a strong ecological risk, the comprehensive ecological risk index of the study area reached the medium ecological risk level. The non-carcinogenic risk HI of soil heavy metals in Kunming City for adults and children were lower than 1, and the non-carcinogenic risk of children was higher than that of adults; the carcinogenic risk to children and adults was within the acceptable range for humans. However, since the current health risk model lacked reference values for carcinogenic slope factors for hand-to-mouth intake and skin contact, it might underestimate the actual carcinogenic risk of heavy metals in the soil.
