Risk Assessment of Heavy Metal Contaminated Dagu River Sediments
In order to investigate heavy metal pollution in Dagu River sediments, 28 sampling sites along the Dagu River were selected and sediment samples were withdrawn. Eight heavy metals including Pb, Cr, Cd, Cu, Ni, Zn, As and Hg were determined for each sample. Fuzzy comprebensive evaluation was used to evaluate the sediment quality, according to the FDEP sediment quality standards, which was improved on the basis of NOAA sediment quality standards. Evaluation results indicate that the pollution of Dagu River sediments by investigated heavy metals is heavy. The contents of Hg, Cu, Ni and Zn in most sampling sediments are far more than the FDEP standards .
