中文摘要：于2013年采集泉州湾海域10种食用鱼样品,分析其中的20种有机氯农药(OCPs)和28种多氯联苯(PCBs)的含量、组成、生物富集以及对人体健康的危害进行风险评估。结果显示,鱼体中OCPs和PCBs的浓度分别为(11.20～74.51)×10^(-9)和(4.48～20.44)×10^(-9 )(湿重),不同鱼种类中污染物含量差别较大,其中棱鮻和斑鰶体中OCPs和PCBs含量最高。鱼体中OCPs主要以DDTs为主,其他化合物含量均较低,且分子标志示踪来源显示,OCPs主要来源于历史残留;而PCBs主要以高氯代PCBs为主。泉州湾食用鱼对DDTs具有较强的富集能力;对PCBs的富集能力随着氯原子数的增加而增强,但氯原子数大于7时富集能力下降。评估显示,泉州湾鱼类体中PCBs的量可能会危及人体健康。并且,棱鮻、斑鰶、黄姑鱼、叫姑鱼、白姑鱼和四指马鲅的每日允许最大摄入量和每月最大允许餐数均低于安全阀值142.2 g/d和16餐/月,建议消费者不要过度食用这些海产品。

外文摘要：Residual levels,composition profiles,bioaccumulation and risk assessment of Organochlorine pesticides and Polychlorinated biphenyls were determined in ten species of edible fish at Quanzhou bay in 2013.Concentrations of OCPs and PCBs ranged from 11.20×10-9~74.51×10-9 and 4.48×10-9~20.44×10-9(wet weight),respectively.Different residual levels of OCPs and PCBs were determined in different fish species,exhibiting highest levels in Liza carinatus and konosirus punctatus.DDTs were the predominant components of OCPs,and the sources of OCPs were mainly derived from historical residue;and the high chlorinated PCBs were the predominant congeners of PCBs.The edible fishes in Quanzhou bay showed strong accumulation capacity to DDTs,and PCBs with less than seven chlorine atoms had higher bioaccumulation potentials with the increase of chlorine atom number,while PCBs with more than seven chlorine atoms were not considered bioaccumulative.The results of assessment showed that PCBs in edible fished from Quanzhou bay may endanger human health.Moreover,the daily dietary consumption of edible fishes and meals per month of Liza carinatus,konosirus punctatus,yellow croaker,Johnius,Argyrosomus and four barbudo were all lower than the safety threshold of 142.2 g/d and 16 meals/month,suggesting that consumers should not overeat these edible fishes.
