Organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs) were determined in nineteen surface sediment samples collected from Baiyangdian Lake and its inflowing river (Fuhe River) in North China. Total concentrations of OCPs, PCBs and PAHs in sediments ranged from 5.4 to 707.6 ng/g, 2.3 to 197.8 ng/g, and 101.3 to 6360.5 ng/g, respectively. The levels of contaminants in Fuhe River were significantly higher than those in Baiyandian Lake. For hexachlorocyclohexane (HCHs) and dichlorodiphenytrichloroethanes (DDTs), alpha-HCH and p,p'-DDT were predominant isomers; while for PCBs, PCB 28/31, PCB 40/103, PCB 60, PCB 101, and PCB 118 were predominant congeners. Possible sources derived from historical usage for OCPs and incomplete combustion fuel, wood, and coal and exhaustion of boats or cars for PAHs. Risk assessment of sediment indicated that sediments in Fuhe River were likely to pose potential biological adverse impact.
在中国北方的白洋淀及其流入河流（府河）采集了 19 个表层沉积物样本，对其中的有机氯农药（OCPs）、多氯联苯（PCBs）和多环芳烃（PAHs）进行了测定。沉积物中 OCPs、PCBs 和 PAHs 的总浓度范围分别为 5.4 至 707.6ng/g、2.3 至 197.8ng/g 和 101.3 至 6360.5ng/g。府河中的污染物水平明显高于白洋淀。对于六氯环己烷（HCHs）和滴滴涕（DDTs），α-HCH 和 p,p'-DDT 是主要的异构体；而对于 PCBs，PCB 28/31、PCB 40/103、PCB 60、PCB 101 和 PCB 118 是主要的同系物。OCPs 的可能来源是历史上的使用以及不完全燃烧的燃料、木材和煤炭，而 PAHs 的可能来源是船只或汽车的废弃。沉积物的风险评估表明，府河沉积物可能会对生物产生潜在的不利影响。
