| 中文摘要 | To characterize the current status and historical trends in organochlorine pesticides (OCPs) contamination in Deep Bay, an important water body between Hong Kong and mainland China with a Ramsar mangrove wetland (Maipo), samples from seawater, suspended particulate matter (SPM), surface sediment, sediment core and fish were collected to determine the OCPs concentrations. Sediment core dating was accomplished using the Pb-210 method. The average concentrations of DDTs, HCHs and chlordanes in water were 1.96, 0.71, 0.81 ng l(-1), while in SPM were 36.5, 2.5, 35.7 ng g(-1) dry weight, in surface sediment were 20.2, 0.50, 2.4 ng g(-1) dry weight, and in fish were 125.4, 0.43, 13.1 ng g(-1) wet weight, respectively. DDTs concentrations in various matrices of Deep Bay were intermediate compared with those in other areas. Temporal trends of the targeted OCPs levels in sediment core generally increased from 1948 to 2004, with the highest levels in top or sub-surface sediment. Both DDT composition and historical trends indicated an ongoing fresh DDT input. A positive relationship between the bioconcentration factor (BCF) of target chemicals and the corresponding octanol-water partition coefficient (K-ow), and between the biota-sediment accumulation factors (BSAF) and the K-ow were observed in the Bay. The risk assessment indicated that there were potential ecological and human health risks for the target OCPs in Deep Bay. (C) 2009 Elsevier Ltd. All rights reserved. |
