摘要
目的了解内蒙古地区食品中铅、镉、总汞的污染水平,为及时发现食品安全隐患和进行风险预警提供基础数据。方法按照2012—2016年内蒙古自治区食品中化学污染物监测计划,结合内蒙古地区地产食品种类及分布特点,采集内蒙古地区12个盟市的本地产食品样品,采用国家食品安全标准方法对样品中铅、镉、总汞进行检测,按照食品污染物限量标准进行评价。结果共采集8类食品,其中监测铅含量的有效样品为4 212份,检出率为32.72%(1 378/4 212),超标率为0.76%(32/4 212),超标的食品类别主要为食用菌(以鲜食用菌计),超标率为7.37%(14/190);监测镉含量的有效样品为4 173份,检出率为54.18%(2 261/4 173),超标率为0.58%(24/4 173),超标的食品类别主要为食用菌(以鲜食用菌计)、水产动物及其制品及肉与肉制品,超标率分别为3.68%(7/190)、2.06%(9/437)及1.15%(6/524);监测总汞含量的有效样品为4 217份,检出率为32.68%(1 378/4 217),超标率为0.50%(21/4 217),超标食品主要为食用菌(以鲜食用菌计)及蔬菜,超标率分别为3.68%(7/190)与1.01%(11/1 088)。结论内蒙古地区生产的食用菌(以鲜食用菌计)、水产动物及其制品、肉与肉制品、蔬菜中存在重金属污染情况,应引起高度重视。
Objective To discover the food contamination of lead,cadmium and mercury and provide basic evidence for the risk assessment. Methods According to the surveillance plan during 2012-2016,samples were collected from 12 regions of Inner Mongolia separately. The lead,cadmium and mercury content in food was measured and evaluated according to the national standards. Results Eight kinds of food were monitored during 2012-2016. 4 212 samples were tested for lead. The detection rate was 32. 72%（ 1 378/4 212）,and the violation rate was 0. 76%（ 32/4 212）. The violation rate was the highest in mushroom,wtih 7. 37%（ 14/190）. 4 173 samples were tested for cadmium,the detection rate was 54. 18%（ 2 261/4 173）,and the violation rate was 0. 58%（ 24/4 173）. The most violations were in mushroom,aquatic products,meat and meat products,with the violation rate of 3. 68%（ 7/190）,2. 06%（ 9/437） and 1. 15%（ 6/524） respectively. 4 217 samples were tested for mercury. The total detection rate was 32. 68%（ 1 378/4 217）,total violation rate was 0. 50%（ 21/4 217）,the most violation were in mushroom and vegetables. The violation rate was3. 68%（ 7/190） and 1. 01%（ 11/1 088）. Conclusion The evidence showed that mushroom,aquatic products,meat and meat products,vegetables were contaminated by heavy metal in Inner Mongolia.
