RESIDUE CHARACTERIZATION OF ORGANOCHLORINE PESTICIDES IN MARINE WATER, SEDIMENT AND OYSTER FROM COASTAL AREA AROUND DALIAN, CHINA
Water, sediment and oyster samples were collected from 15 sampling sites around Dalian, China from October to November, 2008. 20 organochlorine pesticides (OCPs) were detected in all samples analyzed, and DDT was the predominant contaminants in most samples. From all samples, ΣOCPs ranged from 34.866 to 458.715 ng/L and with a mean value of 93.737 ng/L in water, from 11.985 to 846.703 ng/g wet weight (ww, mean = 26.500) in sediment, and from 12.129 to 386.732 ng/g ww (mean = 113.526) in oyster. DDT was observed in all water, sediment and oyster samples, and HCH detected in most samples in present study. Higher endosulfan concentration was observed in oyster samples, but lower in water and sediment ones, suggest air concentration is an important source of oyster. Correlation analysis of total OCPs between sediment and water samples, oyster and water samples suggest that water is the main source of sediment, but not the only source of OCPs in oyster concentration.
