摘　　要：目的了解江西省某县食品中镉污染的现状。方法选择镉污染区与非污染区随机采集104户的粮食、蔬菜、肉禽蛋类304份食品进行检测。结果304份食品的镉超标率为20.40%,其中大米、蔬菜类超标率分别为77.05%和14.15%。两区在镉超标比值总计和蔬菜类上的差异均有统计学意义(χ2=49.022,χ2=37.629,P<0.0001);在镉污染区,粮食和蔬菜类超标比值上差异均有统计学意义(χ2=31.92,P<0.0001)。结论江西省某县镉污染存在区域性分布,其原因与土壤等被镉污染相关。Objective In order to understand the present situation of cadmium pollution in county of Jiangxi province.
