Heavy metals contamination in food in Henan Province in 2010

目的了解河南省部分食品中重金属污染的现状。方法在河南省18个省辖市采集8大类3 657份食品样品,按照国家标准检测食品中铅、镉和汞的含量,检测结果按照GB 2762—2012《食品安全国家标准食品中污染物限量》进行评价。结果河南省部分食品中铅含量的平均值为0.34 mg/kg,总体超标率为8.8%(320/3 656),其中粮食、肉类和蔬菜中超标率较高,分别为17.2%(95/552)、14.5%(85/587)和10.7%(57/534);部分食品中镉含量的平均值为0.054 mg/kg,总体超标率为3.9%(143/3 657),其中食用菌和蛋类中超标率较高,分别为9.6%(49/508)和8.1%(42/518);部分食品中汞含量的平均值为0.077 mg/kg,总体超标率为8.3%(303/3 657),其中蔬菜和粮食中超标率较高,分别为25.3%(135/534)和12.3%(68/551)。结论河南省部分食品中铅、汞污染情况较为严重,其中粮食、蔬菜和肉类食品中污染情况尤为突出,需要加强监管。

Objective To investigate the heavy metals contamination in food in Henan Province in 2010. Methods 3 657 samples of 8 kinds were collected from 18 cities in Henan Province in 2010. The contamination of lead, cadmium and mercury were analyzed respectively according to the standard of GB/T 5009. 12-2003, GB/T 5009. 15-2003 and GB/T 5009.17-2003. The results were evaluated according to the standard of GB 2762-2012. Results The average level of lead, cadmium and mercury in food were 0. 34, 0. 054 and 0. 077 mg/kg, and the violation rates were 8.8% , 3.9% and 8.3%, respectively. The violation rates of lead in cereals, meat and vegetable were 17.2%, 14. 5% and 10.7%, respectively; those of cadmium in edible fungus and eggs were 9.6% and 8. 1% ; and those of mercury in vegetable and cereals were 25.3% and 12. 3%.
