%X A preliminary investigation on the concentration and distribution of chlorobenzenes (CBs) in the water, sediment and aquatic animals of the Pearl River Estuary was carried out. The partition and transference of CBs within the environmental multi-mediums are discussed. The results show that the total concentration of CBs was in the range of 16.44 ng·L-1 to 963.20 ng·L-1 in the top water layer, among which dichlorobenzenes (DCBs) occupied 74.4% averagely. In surface sediments, total CBs ranged from 7.83 ng·g-1 to 40.09 ng·g-1, among which DCBs, trichlorobenzenes (TCBs), tetrachlorobenzenes (TeCBs), pentachlorobenzene (PeCB) and hexachlorobenzene (HCB) occupied 71.4%,11.1%,13.0%,1.2% and 3.6%, respectively, on average. The average content of CBs was 38873.0 ng·g-1 in shellfish, 2360.3 ng·g-1 in fish and 565.0 ng·g-1 in shrimp. DCBs and TeCBs made a greater contribution to the burden of CBs in aquatic animals. Significant concentrating and amplifying phenomena were observed in the transference of CBs from water to sediment and aquatic animals.
