    摘要:

    目的 建立适用于大量风险监测数据快速分级研判的风险分级评价方法。方法 基于食品安全风险评估理论,结合数据分析、文献综述、专家判断等方法,设定涉及食品污染特征、危害物毒性特征、人群食物消费特征以及超标率的分级指标体系、运算关系和赋值标准,并以实际监测数据进行验证应用。结果 建立水产品中重金属风险分级模型,总风险分值=毒性校正含量评分×超标率评分×消费量评分。应用此模型对我国水产品中砷、镉、汞、铅四种重金属进行风险分级,结果显示海蟹、肉食鱼类、非肉食鱼类中镉、甲基汞风险评分较高,可与传统风险评估结果相互验证。结论 该模型可较好地对水产品中重金属进行风险排序,为监管部门提供优先监管的科学依据。

    Abstract:

    Objective To develop a scientific and rapid risk ranking model that is suitable for the analysis of data from food chemicals surveillance system. Methods Based on the principles of food safety risk assessment, a series of index were developed for the contamination and toxicity characteristics of chemicals in food, food consumption characteristics of population, and standards violation rate, respectively. Then the logical operation relationship and the standards for assigning scores were set. The model was verified using real surveillance data. Results Total risk scores were calculated using the equation:total risk score=toxicity adjusted content score × violation rate score × consumption score. This model was applied to the risk classification of arsenic, cadmium, mercury and lead in aquatic products in China. The ranking result were in line with those estimated by the classical risk assessment model. Conclusion The model could rank the health risk of heavy metals in aquatic products properly, and can provide a scientific foundation for regulatory priority.
