摘  要:氯化石蜡(CPs)是一种产量较高的持久性有毒工业化学品,并普遍存在于各种环境基质中.本研究对东海典型海岛城市玉环市常见的8种贝类进行了短链和中链氯化石蜡的定量分析.短链氯化石蜡(SCCPs)的浓度为101-535 ng·g^(−1)dw;中链氯化石蜡(MCCPs)的浓度为100-740 ng·g^(−1)dw.8种贝类的主要CPs为碳链长度为C_(10)的SCCPs和碳链长度为C14的MCCPs.风险评估结果表明,通过贝类摄入CPs对人类健康造成影响可以忽略.Chlorinated Paraffins(CPs)are high-production-volume persistent and toxic industrial chemicals found ubiquitously in various environmental matrices.In this study,short-chain and medium-chain chlorinated paraffins were quantitatively analyzed for eight kinds of shellfish commonly found in Yuhuan city,a typical island city in the East China Sea.The total average concentration of short-chain chlorinated paraffins(SCCPs)was in the range of 101—535 ng·g^(−1)dw,and that of medium-chain chlorinated paraffins(MCCPs)was in the range of 100—740 ng·g−1 dw.The main CPs in eight shellfish were SCCPs with carbon chain length of C_(10) and MCCPs with carbon chain length of C14.Risk assessment results indicate that there is no human health impact from the ingestion of CPs through shellfish.
