摘要
目的了解北京市密云区6类食品中铅污染状况。方法 2013~2015年在辖区内农贸市场、超市、食品店和种养殖基地随机抽取6类食品共363份样品,用石墨炉原子吸收光谱法检测铅含量,按照GB2762-2012《食品安全国家标准食品中污染物限量》进行评价。结果 6类食品样品中铅的总超标率为1.38%,其中生畜肝的铅检出率(100%)及超标率(16.67%)最高。其他5类食品均未超标。结论北京市密云区6类食品中铅的总体超标率较低,但生畜肝中铅污染水平相对较高,应采取措施加以控制。
Objective To explore the status of lead contamination in main food in Miyun district of Beijing.Methods Surveillance on 363 samples from local market,supermarkets,food stores,and planting-aquaculture of Miyun district was conducted from 2013 to 2015.Lead content in food samples were determined by graphite furnace atomic absorption according to GB 2762-2012 National food safety standard maximum levels of contaminants in foods.Results The rate of exceeding national standard of lead limit was 1.38%.Animal viscera were all positive,and the rate of exceeding national standard of lead limit reached at 16.67%.Other 5 types of food samples did not exceed national standard.Conclusion The over-limit rate of lead in food samples collected from Miyun district was relatively low,except in animal viscera,which should be controlled.
