Abstract

Concentrations of Cu, Zn, Fe, Mn, Pb, Cd, As, and Hg were analyzed in the surface water and muscle of seven fish species (Carassius auratus, Cyprinus carpio, Hemiculter leucisculus, Pelteobagrus fulvidraco, Silurus meriaionalis, Ctenopharyngodon idellus, and Parabramis pekinensis) from the Wujiangdu reservoir, China. All metal concen-trations in water were lower than grade one water quality values. Mean metal concentrations in the fish muscle decreased in the order: Zn (10.765 mg kg−1) > Fe (8.908 mg kg−1) > Mn (0.373 mg kg−1) > Cu (0.369 mg kg−1) > Pb (0.158 mg kg−1) > As (0.102 mg kg−1) > Hg (0.042 mg kg−1) > Cd (0.024 mg kg−1). Metal concentrations were higher in omnivorous and carnivorous fish than those in herbivorous fish. The bioconcentration factor (BCF) of Hg was much higher than that of other metals in all fish species. The values of target hazard quotient (THQ) and hazard index (HI) were lower than 1 for fishermen and the general population, indicating that there was no considerable noncarcinogenic risk. However, target cancer risk (TR) values were greater than 1.0 × 10−6, indicating that the car-cinogenic risk caused by fish consumption could not be ignored. Several kinds of fish species were not completely safe for human consumption according to the standard of the European Commission. The potential health risks in fishermen were much higher than that in the general population.
乌江都水库7种野生鱼类肌肉中金属的潜在健康风险评价
分析了乌江都水库7种鱼类(鲫鱼、鲤鱼、银鱼、黄颡鱼、沙颡鱼、沙颡鱼、沙颡鱼和北京对虾)地表水和肌肉中Cu、Zn、Fe、Mn、Pb、Cd、As和Hg的含量。水中金属浓度均低于一级水质值。鱼类肌肉中平均金属浓度降低的顺序为:Zn (10.765 mg kg - 1) > Fe (8.908 mg kg - 1) > Mn (0.373 mg kg - 1) > Cu (0.369 mg kg - 1) > Pb (0.158 mg kg - 1) > As (0.102 mg kg - 1) > Hg (0.042 mg kg - 1) > Cd (0.024 mg kg - 1)。杂食性和肉食性鱼类的金属含量高于草食性鱼类。汞的生物富集系数(BCF)在所有鱼类中均远高于其他金属。渔民和一般人群的目标危害商(THQ)和危害指数(HI)均小于1,表明不存在相当大的非致癌风险。然而,靶癌风险(TR)值大于1.0 × 10−6,表明食用鱼类引起的致癌风险不可忽视。根据欧洲委员会的标准,有几种鱼类对人类食用并不完全安全。渔民的潜在健康风险远高于一般人群。
