Abstract

In this study, some geochemical properties, major elements and trace metals of sediments from a river, an estuary and a lake were researched in the Yangtze River Delta plain—a fluvial plain. The heavy metal contamination levels were evaluated by enrichment factors. Among heavy metals, Cd and Pb revealed the highest risks for sediments. The results of primary component analysis and cluster analysis showed that the metal speciation was associated with sediment sources and components. It is apparent that the metal contaminations are associated with sediment sources which significantly influence the geochemical properties of sediments in the different aquatic environments of the Yangtze River Delta plain
