a b s t r a c tThe distributions of 41 polychlorinated biphenyls (PCBs) were determined in the aqueous phase, suspended particulate matter (SPM), and sediment of the Daliao River estuary in Liaodong Bay, Bohai Sea (China). The total PCB concentrations ranged from 5.51 to 40.28 ng L À1 in the surface water, from 6.78to 66.55 ng L À1 dry weight in the SPM, and from 0.83 to 7.29 ng g À1 dry weight in the sediment. The PCB concentrations in water, SPM, and sediment were moderate relative to those reported for other estuary and marine systems around the world. Sedimentary PCB concentrations decreased offshore due to the active deposition of laterally transported river-borne particles. The predominance of the highly chlorinated congeners for the water, SPM, and sediment samples are an indication of either a lack of degradation or the presence of nearby or recent releases into the environment.

“…Some scholars detected that the total PCBs concentration in water collected from Daya Bay in China and Newark Bay Estuary in the USA were varied from 91.1 to 1355.3 ng l À1 and 3.45 to 56 ng l À1 respectively [8,15]. And the solubility of Aroclor 1254 in seawater has been reported to be as high as 56 mg l À1 [16].…”

“…PCBs are man-made organic compounds that consist of a biphenyl with varying numbers of chlorine atoms substituted on the two six-carbon benzene rings (Dimou et al 2006). PCBs could have 10 homologs and 209 distinct congeners depending on the number and position of chlorine atoms.…”

Levels of polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) in sediments from the sandy flat system of Shuangtaizi Estuary, the highest-latitude estuary in China, were investigated to identify their possible sources and potential ecological risk. The concentrations of 28 PCBs and 18 OCPs ranged from 1.83 to 36.68 ng g(-1) dw (mean 10.53 ng g(-1) dw) and from 0.02 to 14.57 ng g(-1) dw (mean 5.65 ng g(-1) dw), respectively. Generally, these organic pollutants showed an obvious spatial distribution, and relatively high levels were found at the high-tidal zone near river mouths. Compositional analyses indicated that tetra-PCBs were dominant for PCBs, whereas heptachlor was identified to be prevalent for OCPs in surficial sediment in the sand flats of Shuangtaizi Estuary. Overall, Shuangtaizi Estuary had moderate PCB and OCP levels in the sand flat sediments and posed a low ecological hazard to aquatic biota. Our results indicated that the sediment PCBs came from nonpoint deposition, such as atmospheric contribution and river input, for light chlorinated congeners and point source deposition, such as the industrial sources along river flow, for highly chlorinated congeners, whereas OCPs originate mainly from old residuals and new usage of pesticides in agriculture and aquaculture.
