Heavy Metal Pollution in Suzhou Urban Soils and its Health Risk Assessment


Article Preview

An intensive investigation of 55 samples which have been collected from different functional areas was conducted to study the heavy metal distribution in urban soils of Suzhou and to construct the health risk assessment model. From the results of X-Ray fluorescence spectrometer, and comparison with the background of Anhui soils, the average concentrations of Cu、Zn、Pb and Cr were in higher level, indicated that the soils in Suzhou urban has already been polluted by Cu、Zn、Pb and Cr to a certain extent; Concentrations of heavy metal in industrial district, business district and bus station are relatively higher, Cu、Zn、Pb have close connection with transportation and industrial production, Cr mainly comes from the contamination of industrial production, and Ni is under the double influence of household and traffic pollution; Hazard indexes and non-carcinogenic risk for heavy metals in urban soils are below the limits of harmful levels, which represent the lower health risk in Suzhou City.
