为探索农村环境健康状况，选择典型乡镇开展饮用水及农作物重金属和有机氯农药监测，重（类）金属指标包括汞、砷、镉、铅、镍、铜等，有机氯农药指标包括六六六和滴滴涕，分析各指标污染水平，结合中国人群暴露参数，开展健康风险评估。结果表明重金属和有机氯农药通过饮水途径暴露的非致癌风险均小于风险限值，类金属砷通过饮食途径暴露的非致癌风险大于可接受水平，有机氯农药和重金属致癌风险均低于风险限值。%In order to explore the rural environmental health, typical towns were selected to investigate the concentration of heavy metals and organochlorine pesticides in drinking water and crops. The heavy metal indicators, including mercury, arsenic, cadmium, lead, nickel, copper, etc., and the organochlorine pesticides indicators, which includes BHC and DDT, were analyzed, and the Chinese population exposure parameters were combined to carry out health risk assessment. The results showed that the risk of non-carcinogenic heavy metals and organochlorine pesticides in drinking water by way of exposure were below the risk limit, the non-carcinogenic risk of arsenic exposure through diet way was more than the acceptable levels, the total carcinogenic risk of organochlorine pesticides and heavy metals through exposure to drinking water, rice and vegetables were below limits.
