摘　　要：分析我国黄海26个地区贝类生物体中Hg、Cd、Pb、Cr、As、Cu污染状况,并利用美国环境保护署提出的人体健康风险评价模型进行健康风险评价。结果显示,依据《食品安全国家标准食品中污染物限量》(GB 2762—2017)和《无公害食品水产品中有毒有害物质限量》(NY 5073—2006)的污染物限量要求,仅庙岛群岛近岸海域无机砷含量超标。黄海26个地区Cd、As污染健康风险等级均不超过Ⅲ级,远低于美国环境保护署要求的最大可接受风险值,Cd、As污染健康风险强度可以接受。Hg、Pb、Cr、Cu污染风险值均远低于荷兰建设和环境部规定的可忽略风险水平,风险等级符合健康风险评价Ⅰ级标准,健康风险强度可以忽略。The pollution status of Hg, Cd, Pb, Cr, As, and Cu in shellfish organisms in 26 regions of Huanghai Sea was analyzed, and health risk assessment was carried out using the human health risk assessment model proposed by the US Environmental Protection Agency(EPA).The results showed that according to the contaminant limit requirements of “National Food Safety Standard Limits of Contaminants in Foods”(GB 2762-2017)and “Limits of Toxic and Hazardous Substances in Pollution-Free Food and Aquatic Products”(NY 5073-2006),only the inorganic As contents of shellfish in Miaodao islands exceeded the standard.The health risk level of Cd and As pollution in the 26 regions of the Huanghai Sea does not exceed level Ⅲ, which was far lower than the maximum acceptable risk value required by the US Environmental Protection Agency. The health risk intensity of Cd and As pollution was acceptable.The pollution risk values of Hg, Pb, Cr, and Cu were far lower than the negligible risk level stipulated by the Netherlands Ministry of Construction and Environment, the risk grade was the level I standard of health risk assessment, and the health risk intensity was negligible.
