【摘要】：目的掌握河南省面粉及相关制品中重金属铅、镉污染水平。方法采用分层随机抽样的方法在河南省18个省辖市抽取1/3的区(县)作为调查点进行采样;对样品中的铅、镉分别进行检测后进行统计分析。结果 1 364份样品中铅超标61份,超标率为4.47%,其中生干面制品铅的检测值水平较高;1 374份样品中镉超标11份,超标率为0.80%,生干面制品镉的检测值水平较高;8种采样地点类型中,集贸市场、农贸市场所采集样品的铅检测值较高,农贸市场所采集样品的镉检测值为最高;所有样品中同时检测到铅、镉超标的样品共计4份,占样品总数的0.29%。结论研究结果说明河南省面粉及其制品中铅、镉的检测值水平及超标率均较低,铅、镉联合污染的比例也较低。
[Abstract]:Objective to understand the pollution level of heavy metal lead and cadmium in flour and related products in Henan Province. Methods A stratified random sampling method was used in 18 provinces and cities of Henan Province to collect 1 / 3 of the districts (counties) as investigation points, and the lead and cadmium in the samples were detected and analyzed statistically. Results among 1,364 samples, 61 samples exceeded the standard of lead and the rate of exceeding the standard was 4.47.The detection value of lead in raw flour products was higher than that in raw flour products. Among the 1,374 samples, 11 samples were above the standard, and the rate of exceeding the standard was 0.80. The detection value of cadmium in raw flour products was higher than that in other 8 sampling sites. The lead detection value of the samples collected in the market is higher than that in the farmers' market, and the cadmium detection value is the highest in the samples collected by the farmers' market, and the lead is detected simultaneously in all the samples, and there are 4 samples with cadmium exceeding the standard, accounting for 0.29% of the total samples. Conclusion the results showed that the detection value of lead and cadmium in wheat flour and its products in Henan Province was lower and the rate of exceeding the standard was lower, and the proportion of lead and cadmium combined pollution was also lower.
