摘　　要：目的了解镉污染区环境生物样品污染状况和人群镉负荷水平。方法采集当地自产食品进行镉含量测定,检测人群尿镉含量。结果分别在污染区和对照区采集食品809份和88份,采集人群尿样955份和403份。结果显示,污染区食品镉含量高于对照区(包括玉米、叶菜类和根茎类蔬菜),污染区人群尿镉均值和尿镉阳性的比例均高于对照区。结论镉污染区有农产品污染,但人群镉负荷水平处于相对低危害风险的状态。Abstract： Objective To investigate cadmium pollution situation of biological samples in cadmium pollution area and crowed cadmium load level in this area. Methods Locally grown foods were collected for cadmium content detection, meanwhile, the urine cadmium screening was also carried out in local residents. Results There were 809 samples plus 88 samples of food sam- ples, 955 plus 403 urinary samples were collected respectively from ＂polluted area and control area. It was showed that Cd con- tents of food samples from polluted area are higher than that from control area, especially the cadmium content in corn, leafy and root vegetables ; the mean value and positive ratio of urinary cadmium in polluted area residents were higher than that from control area too. Conduasion The results suggested that there was some degree of agricultural products cadmium pollution in cadmium polluted area, but the cadmium load level in polluted area was still at a relatively low risk status of health.
