中文摘要:
      目的 了解上海淡水水产品中多氯联苯(polychlorinated biphenyls, PCBs)和多溴联苯醚(poly brominated diphenyl ethers, PBDEs)的污染状况, 并进行相关的人体健康风险评估。方法 水产品经冷冻干燥后, 经加速溶剂萃取(accelerated solvent extraction, ASE)提取、分散固相萃取(dispersive solid phase extraction, D-SPE)除脂、串联固相萃取(solid phase extraction, SPE)深度净化后, 用气相色谱-串联质谱(gas chromatography-tandem mass spectrometry, GC-MS/MS)检测。结果 14类97件样品中, PCBs的平均检出率为97%, PBDEs的平均检出率为61%~71%。∑51(PCBs)的平均浓度值为2588 pg/g ww, 范围为328~12724 pg/g ww, 中位值为2135 pg/g ww, ∑39(PBDEs)的平均值浓度为454 pg/g ww, 范围为56~2210 pg/g ww, 中位值为 294 pg/g ww。结论 目前上海居民食用淡水水产品不会因PBDEs和PCBs残留而对人体健康构成危险, 但对于大量食用鱼和虾的婴幼儿(一般指2~3岁)应适当减少食用量。
英文摘要:
      Objective To investigate the exposure of polychlorinated biphenyls (PCBs) and poly brominated diphenyl ethers (PBDEs) in freshwater products, and evaluate the human health risk. Methods The aquatic products were freeze-dried, extracted by accelerated solvent extraction (ASE), removed fat by dispersive solid phrase extraction (SPE), deeply purified by solid phase extraction (SPE), and measured with gas chromatography coupled with tandem mass spectrometry (GC-MS/MS). Results Among 97 kinds of samples in 14 classes, the average detection rates of PCBs and PBDEs were 97% and 61%~71%, respectively. The mean concentration of ∑51PCBs was 2588 pg/g ww with the range of 328~12724 pg/g ww and median level was 2135 pg/g ww. The mean concentration of ∑39PBDEs was 454 pg/g ww with the range of 56~2210 pg/g ww and median level was 294 pg/g ww. Conclusion At present, Shanghai residents who eat fresh water products will not be in danger of human health due to the residue of PBDEs and PCBs, however, infants and young children (generally 2~3 years old) who consume large amounts of fish and shrimp should reduce their consumption.
