摘　　要：对厦门西海域拟疏浚物中的PCBs含量及分布特征进行了调查,结果表明,厦门西海域拟疏浚物中PCBs为0.17 ng/g～30.3 ng/g,其中马銮湾2个站位PCBs的总含量高于《海洋沉积物质量》(GB 18668-2002)一类标准值。生态风险评价结果显示厦门西海域拟疏浚物中多氯联苯的环境毒性相对较低。The concentration and distribution of PCBs in the dredged materials on the western men were investigated. The results indicated the concentrations of the dredged material samples bay of Xia- varied from 0.17 ng/g to 30.3 ng/g. The PCBs concentrations of all sampling sites were lower than the value of Category [ of Quality Standards for Ocean Sediment （ State Standard 18668 - 2002） except two in the Maluan bay. The ecological risk assessment showed the relative low PCBs level in the Xiamen dredged materials was relative low toxicity to the environment.
