Studies on Coplanar-PCBs and PCNs in Edible Fish and Duck in Qingdao and Chongming Island

  • 摘要: 利用HRGC-HRMS测定了青岛海鱼和上海崇明岛淡水鱼、鸭样品中共平面多氯联苯(co-PCBs)和多氯萘(PCNs)(均以脂肪计)的质量分数,并根据每日摄取量可能带来的健康风险进行了初步探讨. 青岛海鱼中w(co-PCBs)和w(PCNs)平均值约为4 041和225 pg/g,崇明岛淡水鱼约为3 318和640 pg/g. 崇明岛鸭肉中w(co-PCBs)和w(PCNs)平均值分别约为966和43.8 pg/g. 青岛海鱼中PCNs同系物组成(以5-CNs和3-CNs为主)与崇明岛淡水鱼完全不同. 与国内外其他地区鱼和家禽相比,其污染物含量均较低. 所有样品中co-PCBs的毒性当量浓度(WHO-TEQ)为0.68~11.40 pg/g,PCNs的毒性当量浓度(WHO-TEQ)为0.001~0.210 pg/g. 根据当地人群的饮食习惯,两地人群co-PCBs和PCNs每日摄入量远低于WHO对普通人群规定的每日容许摄入量,因此不会对人群健康产生严重的负面效应.
