Statistical Analysis of Heavy Metals in Bottom Sediments from the Tuo River in Suzhou City, China and its Implications for Source Identification
Abstract:
Heavy metal (Zn, V, Cr, Co, Cu and Pb) concentrations in bottom sediments from Tuo River in Suzhou City have been analyzed for determing their average levels and distribution concentrations, and statistical analysis (correlation, cluster and principle component) have been taken place for evaluating their lithogenic and/or anthropogenic sources. The results imply that the concentration of metals following the order Co>Zn>V>Cr>Cu>Pb with homogeneous distribution. The lithogenic metals (V, Cr and Co) are enriched out of the city, whereas the anthropogenic (industry and vehicle related) metals (Zn, V, Cu and Pb) are enriched in the city.
