| 摘 要： | 利用气相色谱质谱仪(GC-MS)对广东罗非鱼主要养殖区水体及罗非鱼肌肉中16种优控多环芳烃(PAHs)的含量进行检测,并用美国环保局(USEPA)推荐的健康风险评价模型对罗非鱼食用安全进行健康风险评价。结果表明:水体中16种多环芳烃总量为272.53 ng·L-1,范围为53.55~679.97 ng·L-1;罗非鱼肌肉PAHs残留含量范围为182.66~717.20 ng·g-1,平均含量为355.28 ng·g-1;多环芳烃的组成以低环为主,在水体及罗非鱼肌肉所占比例分别为69.64%~97.09%和59.70%~74.46%;罗非鱼经食用所含6种致癌PAHs造成个人年致癌风险值范围为2.87×10-6~1.56×10-5a-1,低于国际辐射防护委员会(ICRP)推荐的最大可接受风险水平(5.0×10-5a-1),但存在一定的致癌风险,8种非致癌PAHs有害污染物对人体的总非致癌风险为2.51×10-10~1.54×10-9a-1,低于国际标准值,健康风险较低。

| Abstract: | Polycyclic aromatic hydrocarbons(PAHs) have caused water and aquatic product pollution. In this study, the residual levels of 16 priority PAHs in water and Tilapia samples collected from fish ponds, markets and supermarkets in four cities of Guangdong Province were measured by GC-MS. The health risk model recommended by USEPA was used to assess health risk of these fish products. Total concentrations of 16 priority PAHs in the water ranged from 53.55 ng·L-1 to 679.97 ng·L-1, averaging 272.53 ng·L-1, while the contents of PAHs in aquatic products ranged from 182.66 ng·g-1 to 717.20 ng·g-1, with the average concentration of 355.28 ng·g-1. The predominant PAHs in the water and the fish were low-molecular ones, which accounted for 69.64%~97.09% and 59.70%~74.46%, respectively. The carcinogenic risk indexes of 6 PAHs through the fish consumption ranged from 2.87×10-6 a-1 to 1.56×10-5 a-1, with 8.96×10-6 a-1 and 3.54×10-6 a-1 for the town and county residents, respectively. The non-carcinogenic risk indexes of 8 PAHs varied from 2.51×10-10 a-1 to 1.54×10-9 a-1, much lower than the maximum tolerable value(5.0×10-5 a-1) recommended by the International Commission on Radiological Protection. |
