Abstract:On the basis of chemical sequential extraction, statistics, principal component analysis (PCA) and positive matrix factorization (PMF), we identified the characteristics of Pb distribution, pollution and sources in cropland soils of Renyang district of Changshu city, a typical industry-based peri-urban area in China. Pb presented significantly enrichment in the topsoil, and the mean concentration of topsoil Pb exceeded approximately one time of the local background value. The exogenous Pb in the topsoil was mainly bound to Fe/Mn oxides and residual fractions. Compared to the topsoil, the deeper soils presented the higher proportions of Pb bound to carbonates and residual Pb, but the lower proportions of Pb bound to Fe/Mn oxides and Pb bound to humus acid, respectively. PCA and PMF revealed four primary factors with the following contribution rates to Pb in the soil: natural geologic process (42.8%), exhaust from vehicle (leaded petrol) and combustion of fossil fuel which were delivered by atmospheric deposition (15.5%), industrial emissions involved the nonferrous metals such as electroplating (21.6%), and other mixed sources in the terrestrial geochemical process (20.1%). The results of the PCA and PMF methods used for source apportionment of Pb were in good agreement.
