摘　　要：为评估毕节市市售马铃薯中重金属含量及其食用后对人体健康产生的影响,在2022年7—8月从8个县(市、区)抽取40份样品,采用电感耦合等离子质谱法测定铅(Pb)、铬(Cr)、汞(Hg)、镉(Cd)、砷(As)的含量。采用单因子污染指数评价重金属的污染水平,Nemerow综合污染指数评价健康风险,目标危害系数法评估膳食风险。结果显示,马铃薯中Pb、Cr、Hg、Cd、As含量均低于国家标准限值,5种重金属污染水平较低,成人或儿童食用毕节市市售马铃薯无明显健康风险,处于安全水平。To evaluate the content of heavy metals in potatoes sold in Bijie city and their effects on human health after consumption,40 samples were taken from 8 counties(cities and districts)from July to August 2022.The contents of lead(Pb),chromium(Cr),mercury(Hg),cadmium(Cd)and arsenic(As)were determined by inductively coupled plasma mass spectrometry.The pollution level of heavy metals was evaluated by single factor pollution index,the health risk was evaluated by Nemerow comprehensive pollution index,and the dietary risk was assessed by the target hazard factor method.The results show that the contents of Pb,Cr,Hg,Cd and As in potatoes are all lower than the national standard limits,and the pollution levels of 5 heavy metals are low.There is no obvious health risk for adults or children eating potatoes from Bijie city,and the dietary intake is at a safe level.
