  • 摘要: 为了解大亚湾常见野生海产品中重金属的含量及其摄食的健康风险，本文分析了大亚湾10种野生海产品可食用部分中7种重金属（As、Cd、Cr、Cu、Pb、Ni、Zn）含量，并采用单因子污染指数（Pi）、综合污染指数（Pc）方法评价其污染程度，进一步采用美国环保署推荐的健康风险评估模型评估其摄食的健康风险.结果表明，7种重金属含量分别为4.28×10-2-1.31×10-1、8.58×10-5-2.19×10-2、2.69×10-3-9.54×10-3、1.92×10-2-3.05×10-1、ND-2.14×10-2、8.40×10-4-2.75×10-1、1.92×10-1-6.13×10-1 mg·kg-1（湿重）.与国内外其它地区相比，处于相对较低水平；与历史数据相比，呈现降低趋势.Pi及Pc结果表明，金钱鱼、平鲷、口虾蛄和棒锥螺中As处于轻度污染水平，其余重金属均处于无污染水平.风险评估结果表明，大亚湾海产品可食用部分中总砷的摄食致癌风险较高，儿童/青少年的致癌风险高于成人1.5倍.金钱鱼、口虾蛄、杜氏枪乌贼、近缘新对虾、蟹和棒锥螺的日均消费量（成人57.4 g·d-1，儿童/青少年42.4 g·d-1）均高于消费建议中给出的相应安全阈值，建议消费者适当控制这些海产品的日食用量和月食用餐数.As在海产品中较高的检出，需予以进一步关注.
    Abstract: Herein, seven typical heavy metals (As, Cd, Cr, Cu, Pb, Ni and Zn) were measured in the muscle tissues of wild marine organisms collected from Daya Bay, South China. The concentrations of As, Cd, Cr, Cu, Pb, Ni and Zn in muscle tissues ranged from 4.28×10-2 to 1.31×10-1, from 8.58×10-5 to 2.19×10-2, from 2.69×10-3 to 9.54×10-3, from 1.92×10-2 to 3.05×10-1, from ND (not detectable) to 2.14×10-2, from 8.40×10-4 to 2.75×10-1, and from 1.92×10-1 to 6.13×10-1 mg·kg-1(wet weight), respectively. Compared with those reported levels from other places, either domestic or foreign, the metal contamination levels in marine organisms from Daya Bay were relatively low. Compared with the historical data, a decreasing trend was found for the concentrations of the seven investigated heavy metals in the present study. Furthermore, the single factor pollution index method (Pi) and comprehensive pollution index method (Pc) were used to evaluate the pollution levels of heavy metals. The results of Pi and Pc showed that only As in the Scatophagus argus, Rhabdosargus sarba, Oratosquilla oratoria and Turritella terebra bacillum exceeded the allowable criteria of "the Light Pollution", while all the other metals can be considered as "non-polluted". The US EPA recommended model for health risk assessment was performed to further explore the potential human health risks of intaking heavy metals through dietary. The results showed that As was the main risk factor with potential accumulation for long-term consumption of marine organisms, which would generate a cancer risk. The exposure risk for children/adolescents was 1.5 times higher than that of adults in Guangdong Province. Moreover, the daily dietary consumption (57.4 g·d-1 for adults and 42.4 g·d-1 for children/adolescents) of Scatophagus argus, Oratosquilla oratoria, Loligo duvaucelii, Metapenaeus affinis, Brachyura and Turritella terebra bacillum were higher than the corresponding safety threshold of consumption recommended by US EPA. We therefore suggest that consumers should properly control the daily consumption and number of monthly meals for these seafoods. Meanwhile, more attention should be paid to the potential health risk of total As to human via consumption of marine organisms from Daya Bay.
