中文摘要:

      目的 了解2019年河北省市售虾蛄中重金属污染情况。方法 按照《2019年河北省食品污染物风险监测方案》的要求, 对河北省11个地市及雄安新区共计106份虾蛄样品进行Pb、Ni、Hg(总)、As(总)、Li、V、Mn、Ba、Cd、Cr、Al、Sb、Cu、Sn、Se共15种元素的检测, 并对检测结果进行统计分析。结果 Hg、As、Mn、Cd、Cu、Se的检出率为90%以上, As、Cd的检出率达到了100%, 其余元素的检出率在36.8%～89.6%之间, 元素镉超标率达到了86.8%。Pb、Ni、Hg(总)、As(总)、Li、V、Mn、Ba、Cr、Al、Sb、Cu、Sn、Se元素均检出, 但并未超出GB 2762—2017《食品安全国家标准 食品中污染物限量》中的限值要求。结论 去除虾腺可降低镉元素的检测值, 虽然河北省虾蛄抽查样品89.9%镉超标, 但经过计算评估, 虾蛄中的镉元素对人体健康的风险可以接受。

英文摘要:

      Objective To understand the pollution of heavy metals in shrimps sold in Hebei provincein 2019. Methods According to the requirements of Hebei food pollutant risk monitoring program in 2019, the total of 106 samples from 11 cities and Xiong'an new district of Hebei province were tested for 15 elements [Pb, Ni, Hg (total), As (total), Li, V, Mn, Ba, Cd, Cr, Al, Sb, Cu, Sn, Se], and the test results were statistically analyzed. Results The detection rates of Hg, As, Mn, Cd, Cu and Se were more than 90%, while those of As and Cd were 100%, the detection rates of other elements were 36.8%?89.6%, and the exceeding standard rate of elemental cadmium was 86.8%. The Pb, Ni, Hg (total), As (total) and Li, V, Mn, Ba, Cr, Al, Sb, Cu, Sn, and Se were detected. However, it did not exceed the limit requirement of GB 2762—2017 National food Safety standard-Maximum levels of contaminants in foods. Conclusion The removal of shrimp glands can reduce the detection value of cadmium. Although 89.9% of shrimp samples in mantis shrimps in Hebei province exceeded the cadmium level, the risk of cadmium in mantis shrimps to human health is acceptable after calculation and evaluation.
