摘　　要：目的了解北京市丰台区部分市售食品中镉的污染状况。方法采取分层随机抽样方法,2011—2012年间采集丰台区大型农副产品批发市场、商场超市、农贸市场共6类215份市售食品样品,按照GB/T 5009.15—2003《食品中镉的测定方法》对样品进行前处理,采用石墨炉原子吸收光谱法检测镉含量。结果 2011—2012年监测样品中镉的检出率为76.7%(165/215);按照GB 2762—2012规定的限量值,以及根据鲜香菇的含水量进行折算后的干香菇的限量值进行比较,则2011—2012年监测样品的合格率为100%。结论丰台区各类市售食品镉污染水平总体是安全的,但各类市售食品都有检出镉,说明存在不同程度的污染,需要加强监测,控制污染,保障人群的健康。Objective To understand the status of cadmium pollution in Fengtai District of Beijing and to provide the scientific basis for removing polluted foods. Methods 215 food samples from wholesale markets, farm product markets, supermarkets were collected using stratified random sampling in 2011-2012. The contents of cadmium in foods were determined by graphite furnace atomic absorption spectrometry based on the national standard method GB/T 5009. 15-2003. Results The positive rate for cadmium was 76.7% （165/215）. According to GB 2762 - 2012, the value of fresh mushrooms was converted into dried mushrooms, and the qualification rates in 215 food samples in 2011 -2012 was 100%.
