Persistent organochlorine residues in sediments of Hong Kong Victoria Harbour and Xiamen Western Bay
摘要
Abstract
Samples of surface sediment were collected from Victoria Harbour
Hong Kong (Aug. 1992)
and Xiamen Western Bay (Nov. 1993)
and analysed for organochlorine (OC) pesticides (HCHs
DDTs) and polychlorinated biphenyls (PCBs). Concentration ranges of HCHs
DDTs and PCBs in the survey area of Victoria Harbour were from undetectable to 9.4 μg/kg
1.38–97 μg/kg and 3.2–81 μg/kg
respectively; those for Xiamen Western Bay were 0.14–1.12 μg/kg
4.45–311 μg/kg and 0.05–7.24 μg/kg
respectively. The determined residue levels and distribution patterns of these organochlorines are discussed
and the Harbour and Bay contamination levels are compared. Two sediment cores were collected (Oct. 1994) from Xiamen Western Bay for study on the vertical profiles and pollution history of the above contaminants. The vertical profile characteristics indicated that the inner part of Xiamen Western Bay was once polluted by PCBs moderately and that there are still new inputs of DDT.
