Abstract

From sediment samples collected in the lower reach of Changjiang River (from Nanjing to Shanghai), the AA. examine the correlation between heavy metals and geochemical indices, including Fe2O3, Al2O3, total organic carbon (TOC) and black carbon (BC), as well as magnetic susceptibility (MS). Using these indices they investigate the contamination characteristics of heavy metals in the sediments with Principal Component Analysis (PCA). The results indicate that the combination of geochemical and multivariable statistical methods clearly characterizes the geochemistry of heavy metals in sediment of the lower reaches of the Changjiang River and suggests that power plants are the main source of heavy metal pollution
