摘要
目的:采用液相色谱与电感耦合等离子体质谱联用分析法(LC-ICP-MS),测定广东沿海海域海产品中三苯基锡含量,探明广东沿海海产品有机锡的污染状况。方法:有代表性地采集广东海域17个海区及部分市售海产品,样品冻干处理制成干粉,加入流动相经超声萃取、离心、过滤等处理后,用液相色谱与电感耦合等离子体质谱联用分析法测定三苯基锡含量。结果:所检测的32种共112个海产品样品中,以湿重计算的三苯基锡含量最高的为324.1 ngSn/g,平均浓度是44.9 ngSn/g。结论:广东沿海海域海产品已受到一定程度的有机锡污染,不同种类海产品中普遍检出三苯基锡。
Objective ：To determine the contents of TPT in seafood in Guangdong by LC -ICP -MS to provide basic data for the levels of organotin pollution. Methods：The survey collected samples widely and representatively from 17 commercial seafood beds and some retailors around Guangdong. TPT was extracted in an ultrasonic bath with acetonitrile/water/acetic acid （65/23/ 12） plus 0. 05% trethylamine solvent from seafood samples. The extracts were filtered before being analyzed by LC -ICP- MS. Results：The highest concentration of TPT was 324. 13 ngSn/g wet weight and the average concentration was 44. 87 ngSn/g wet weight. Conclusion：The seafood from Guangdong is polluted by organotin to certain degree and the pollution in seafood by TPT is widespread.
