| 摘 要： | 为了解我国东部沿海地区海产品与淡水产品中重金属污染现状及摄入风险，实验分析了东部沿海地区市售的12种海产品和8种淡水产品，采用微波消解-电感耦合等离子体质谱法（ICP-MS）测定铅、镉、汞、砷、铬共5种常见重金属，根据单因子污染指数（Pi）和金属污染指数（MPI）评价其污染程度，比较不同水产品重金属含量差异及污染状况，并通过靶标危害系数（THQs）评价其健康风险。检测结果显示，海产品与淡水产品中，铅含量范围为ND～1.100 mg/kg，铅超标率为1.4%，各品种铅均值含量无显著差异。镉含量范围为ND～1.600 mg/kg，镉超标率为2.8%，长牡蛎、海湾扇贝镉均值含量高于其他品种。总汞含量范围为ND～1.900 mg/kg，蓝鳍金枪鱼总汞均值含量高于其他品种，其他品种总汞均值含量无显著差异。总砷含量范围为0.004～4.100 mg/kg，淡水鱼（乌鳢除外）总砷均值含量低于其他品种。铬含量范围为0.010～32.000 mg/kg，铬超标率为2.3%，鳙铬均值含量高于其他品种。单因子污染指数显示：不同品种的水产品都有一定的污染。重金属污染指数显示：污染指数呈现...

| Abstract: | In order to understand the pollution status and ingestion risk of heavy metals in seafood and fresh water products in eastern coastal areas, 12 kinds of seafood and 8 kinds of fresh water products on the market were analyzed in this study. Microwave digestion-inductively coupled plasma mass spectrometry (ICP-MS) method was used to determine five kinds of common heavy metals, including lead, cadmium, mercury, arsenic and chromium. The pollution degree was evaluated according to single factor pollution index (Pi) and metal pollution index (MPI), the content difference of heavy metals in different aquatic products and pollution status were compared, and the health risk was evaluated by target hazard quotients (THQS). The test results show that the lead content in seafood and freshwater products was in the range of ND-1.100 mg/kg, the lead exceeding rate was 1.4%, and the average lead content of each species had no significant difference (P>0.05); the range of cadmium content was ND-1.600 mg/kg, the cadmium exceeding rate was 2.8%, and the average content of cadmium in Crassostrea gigas and Argopecten irradians was higher than other varieties (P<0.05); the mercury content range was ND-1.900 mg/kg, the average total mercury content of Thunnus maccoyii was higher than other species (P<0.05), and there was no significant difference in the average total mercury content of other species (P>0.05); the range of total arsenic content was 0.004-4.100 mg/kg, and the average total arsenic content of freshwater fish (except Channa argus) was lower than other species (P<0.05); the chromium content range was 0.010-32.000 mg/kg, the chromium exceeding rate was 2.3% and the average chromium content of Aristichthys nobilis was higher than other species (P<0.05). The single-factor pollution index showed that: different types of aquatic products have certain pollution; the heavy metal pollution index shows the trend of seawater shrimp and crab>seawater shell>freshwater shrimp and crab>sea fish>freshwater fish. The health risk assessment showed that except for T. maccoyii, the health risk values of marine products and freshwater products were less than 1.0, and the risk when eating was relatively small. The results of this study show that seafood and freshwater products in the eastern coastal areas have a certain degree of heavy metal pollution, but the pollution is lighter and the intake risk is relatively small. |
