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C10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.
Abstract
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 C10 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.
