ABSTRACT
The concentration, spatial distribution, homologue profiles, sources, toxicity and risk of PCBs in
urban stream sediments from a national eco-industrial park named Suzhou Industrial Park (SIP) in
China were investigated in this work. Concentrations of ΣPCBs varied from 0.13 to 4.7 ng g-1, with an
average value of 1.7±1.2 ng g-1. Spatial variations indicated that PCB concentrations had no correlation
with land uses in the SIP. Tetra-PCBs and hexa-PCBs were the most abundant PCB homologues, which
were different from those found in Chinese commercial PCBs and might be mainly derived from other
sources. The potential toxicity and risk of PCBs here might be negligible based on the total equivalent
concentration (TEQ) analysis and sediment quality guidelines (SQG).
