目的了解潍坊市1 2县市区超市、集贸市场、零售点出售的部分食品重金属污染状况,以便食品安全监管部门采取相应、合理的食品安全监管措施,为我市市售食品安全提供可靠保障。方法 2016年共采集8大类食品420份,应用石墨炉原子吸收法测定铅、镉、铬含量,应用原子荧光分光光度法测定砷、汞含量。结果在所检测的420份样品中,汞合格率为98.1%,铅合格率为97.6%,镉合格率为95.2%,砷合格率为96.7%,铬合格率为100.0%。超标样品以皮蛋中的铅超标率最高,最大超标倍数达7.28。结论潍坊市食品重金属污染情况总体比较乐观,但部分种类仍存在某种元素超标现象,望相关部门加强监督执法力度,确保人民群众餐桌安全。
Objective To understand the status of heavy metal pollution in some foodstuffs sold by supermarkets, markets and retail outlets in 12 counties of Weifang City so that food safety regulatory authorities can take appropriate and reasonable food safety supervision measures to provide reliable protection for the commercial food safety in our city . Methods A total of 420 food samples were collected from eight major categories in 2016. The contents of lead, cadmium and chromium were determined by graphite furnace atomic absorption spectrometry. The contents of arsenic and mercury were determined by atomic fluorescence spectrometry. Results Among the 420 samples tested, the pass rate of mercury was 98.1%, the pass rate of lead was 97.6%, the pass rate of cadmium was 95.2%, the pass rate of arsenic was 96.7% and the pass rate of chromium was 100.0%. Exceeded samples to preserved eggs in the lead exceeding the highest rate, the maximum exceed standard multiple of 7.28. Conclusion Weifang City, the overall situation of food heavy metal pollution is more optimistic, but some species still exist some elements of excessive standards, hope the relevant departments to strengthen supervision and law enforcement efforts to ensure that the people table safe.
