虾姑中镉和无机砷污染状况及健康风险评估

Pollution status and health risk assessment of cadmium and inorganic arsenic in shrimps

目的监测海南省市售虾姑中重金属镉和无机砷的含量,并对其进行健康风险评估。方法 2021年5—7月采集海南省6个市县(儋州市、临高县、乐东县、文昌市、三亚市、琼海市)农贸市场的虾姑样本共60份,采用电感耦合等离子体质谱仪、液相色谱-原子荧光光谱仪进行分析测定,并采用国家限量标准法、单因子污染指数法、内梅罗污染指数法及健康风险指数进行评估。结果 60份虾姑中镉和砷的检出率为100%,其中镉的超标率为93.3%,均未检出无机砷。结论通过对海南省6个市县农贸市场的虾姑进行抽样检测发现,虾姑中镉污染含量较高,对人体健康危害较大,需引起高度重视。建议相关部门及时更新有关污染元素的限量标准,保障海产品食品的安全。

Objective To monitor the contents of heavy metals cadmium and inorganic arsenic in dried shrimps sold in Hainan Province and carry out health risk assessment.Methods From May to July 2021,a total of 60 shrimp samples were collected from farmers'markets in six cities and counties of Hainan Province(Danzhou City,Lingao County,Ledong County,Wenchang City,Sanya City,Qionghai City).The samples were analyzed by inductively coupled plasma mass spectrometry,liquid chromatography atomic fluorescence spectrometry,and evaluated by national limit standard method,single factor pollution index method,Nemero pollution index method,and health risk index.Results The detection rate of cadmium and arsenic in 60 samples of dried shrimps was 100%,of which the over standard rate of cadmium was 93.3%,and no inorganic arsenic was detected.Conclusions Through the sampling inspection of shrimps from farmers'markets in six cities and counties in Hainan Province,it is found that cadmium pollution content in shrimps is high,which is harmful to human health,and should be paid great attention to.It is suggested that relevant departments should update the limit standards of relevant polluting elements in time to ensure the safety of seafood food.
