Spatial Distribution and Assessment of Soil Heavy Metals in Suburb Cropland, Suzhou City, Anhui, China

Abstract:

In this paper, concentrations and spatial distribution of four heavy metals (Cu, Pb, Zn, As) in cropland soil from suburb area of Suzhou city were determined and analysed by X-Ray fluorescence spectrometer and interpolation analysis. Then based on integrated pollution index (IPI), pollution levels of the heavy metals were assessed. The results indicate that the mean concentrations of As was higher than the value of Anhui soil background, while the others were lower; Spatial distribution of Pb and Zn were affected by traffic pollution, Cu was related with the emissions of garbage and waste, As was came from the use of pesticides; The IPI of heavy metals belonged to light pollution levels, and As was higher than the others.
