| 中文摘要 | Residues of organochlorine pesticides (OCPs), hexachlorocyclohexanes (HCHs), and dichlorodiphenyltrichloroethanes (DDTs) and their environmental risks in surface sediments collected from marine and adjacent riverine/estuarine areas in the northern Bohai Sea, China, were investigated. Concentrations of I HCH pound and I DDT pound in sediments ranged from below detection (< LOD) to 1964.97 ng g(-1) dry wt (dw; mean, 92.51 ng g(-1) dw) and < LOD to 86.46 ng g(-1) dw (mean, 9.23 ng g(-1) dw), respectively. Concentrations of HCH and DDT were generally higher in marine than riverine sediments. Concentrations of HCH and DDT residues found in the present study were higher than those reported in marine and river/estuary sediments from other areas of the world. The source of HCH in sediments could be explained by the large amount of historical use, while DDT seemed to be a combination of erosion of the weathered soils and long-range atmospheric transport. Concentrations of HCH in sediments from the study areas did not exceed sediment quality guidelines (SQGs), with the exception of gamma-HCH. However, risks posed by concentrations of DDT observed in sediments were found to be moderate to high compared with those posed by consensus-based SQGs. Although the mean sedimentary concentrations of HCH and DDT found in the area of the northern Bohai Sea, China were lower than suggested SQGs in general, their concentrations in some locations were close to or above the SQGs for adverse effects in benthic organisms and, thus, remain a cause for concern. |
