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 To understand the status of cadmium pollution in foodstuffs of a county in Jiangxi Province. Methods A total of 304 foodstuffs of 104 households, including food, vegetables and meat and eggs, were randomly collected from cadmium-contaminated and non-contaminated areas. Results The over-standard rate of cadmium in 304 food products was 20.40%, of which the exceeding standard rates of rice and vegetables were 77.05% and 14.15% respectively. There were significant differences between the two groups in the total cadmium ratio and the vegetables (χ2 = 49.022, χ2 = 37.629, P <0.0001); in the cadmium-contaminated area, there was a significant difference in the exceeding ratio of grain and vegetables (χ2 = 31.92, P <0.0001). Conclusions There is a regional distribution of cadmium pollution in a county in Jiangxi Province, which is related to the fact that soils are contaminated by cadmium.
