中文摘要:

      目的 采用新、旧两版GB 16740标准对上海市保健食品中铅、砷、汞残留量进行分析与评价, 了解重金属污染状况及评价标准改变带来的变化。方法 采用国家标准规定的检测方法, 对2011~2015年上海市收检的保健食品进行铅、砷和汞残留量测定, 并使用SPSS 19.0对测定结果进行统计分析。结果 上海市2011~2015年共检测保健食品7306份, 按旧版GB 16740评价, 总合格率为96.17%, 铅、砷和汞残留量总超标率分别为3.09%、1.46%和0.22%; 按新版GB 16740评价, 总合格率为98.06%, 铅、砷和汞残留量总超标率分别为1.28%、0.94%和0.22%, 超标样品中胶囊剂和茶剂居多。结论 上海市保健食品中铅、砷、汞污染水平总体较低, 新版的评价标准改变了原标准中根据剂型判断结果的模式, 使得结果评价更为合理。

英文摘要:

      Objective To investigate the contamination status of heavy metals and the changes caused by using the old and new edition of GB16740 standards. Methods The content of Pb, As and Hg in inspected health food was determined from 2011 to 2015 by using two editions of national standard methods, and the results of statistical analysis were analyzed using the SPSS 19.0 software. Results Among all the 7306 samples from 2011 to 2015, the total pass rate was 96.17% and the exceeding standard rates of Pb, As and Hg were 3.09%, 1.46% and 0.22%, respectively, evaluated by the old edition of GB 16740. The total pass rate was 98.06% and the exceeding standard rates of Pb, As and Hg were 1.28%, 0.94% and 0.22%, respectively, evaluated by the new edition of GB 16740. The majority of the samples exceeded the national standard were capsules and medicinal teas. Conclusion The heavy metal contaminations in health food in Shanghai were at a low level. The new evaluation standard changed the pattern based on the formulations of the old standard to achieve more reasonable results.
