| 摘 要： | 目的建立气相色谱-负化学离子源-质谱法检测海产品中8种代表性多溴联苯醚(polybrominated diphenyl ether, PBDEs)的分析方法。方法冻干后的样品经加速溶剂提取,硅胶氧化铝复合层析柱净化后,采用气相色谱-负化学离子源-质谱(GC-NCI-MS)联用仪分析,内标法定量。结果不同地区海鱼中PBDEs的污染水平无显著差异,Σ_(3-7)BrPBDEs的平均值为24.0ng/g湿重,BDE209的平均值为20.7ng/g湿重。海鱼中BDE209的含量最高(占样品总量的46.2%),其次是BDE47(14.9%), BDE28(1.2%)的贡献率最低。结论 PBDEs污染水平虽然不高,但与沿海居民健康密切相关,应持续关注海域环境中生物体内PBDEs的污染状况。
