2008—2011年河南省保健食品铅、砷、汞污染状况分析

Ananlysis of Pb,Hg and As in health foods in Henan province from 2008 to 2011

目的了解保健食品中铅、砷、汞污染状况。方法采用国家标准规定的检测方法,对2008—2011年河南省保健食品进行铅、砷、汞含量测定,并用SPSS 13.0软件对测定结果进行分析。结果 851份样品中铅、砷和汞总检出率分别为32.37%、66.67%和63.83%;总超标率分别为8.42%、7.97%和1.86%;均值分别为1.03、0.44、0.08 mg/kg;不同原料铅、汞含量均值为植物类>动物类>补充剂,不同原料砷含量均值为动物类>植物类>补充剂;不同剂型铅含量均值为丸剂>颗粒>胶囊>片剂>液体,砷和汞含量均值为丸剂>胶囊>颗粒>片剂>液体;同一产品中同时检出2种以上重金属占59.93%,以同时检出铅和砷居多,占44.90%。结论保健食品的铅、砷、汞污染较普遍,超标比较严重,其污染主要与植物和动物性原料有关。

Objective To understand the contamination status of Pb, Hg and As in health foods. Methods Health food samples from 2008 to 2011 were tested for Pb, As and Hg by national standard methods, and data were analyzed with SPSS 13.0 software. Results The detection rates of Pb, As and Hg among 851 samples were 32.37% , 66. 67% and 63.83% , respectively. 8.42% , 7.97% and 1.86% of the samples failed to pass the national standars, with means of 1.03, 0.44 and 0. 08 mg/kg for Pb, As and Hg, respectively. The descending order for Pb and Hg contamination was plant products, animal products and nutritional supplements. The descending order for As was animal products, plant products and nutritional supplements. The descending order for Pb in different formulation was pills, granules, capsules, tablets and liquids, while for As and Hg was pills, capsules, granules, tablets and liquids. 59.93% of the samples were positive for more than one contaminant of Pb, Hg and As, Pb and Hg were detcted simultaneously in 44.90% of the samples. Conclusion Contamination of Pb, Hg and As in health foods were common and serious, and mainly related to food materials fro, plants and animals.
