【摘要】 为了解饮水型砷中毒皮肤损害与饮水砷含量、砷暴露剂量的关系,调查了砷中毒病区常住居民793人,分析了饮水砷含量、总砷摄入量与患病率的关系。结果表明:皮损患病率与水砷含量、总砷摄入量呈正的直线相关关系(r=0.960、r=0.683)并得出该关系的方程表达。总砷摄入量与患病率呈一定的剂量反应关系。更多还原

【Abstract】 In order to understand the relationship between arsenic concentration and dose in water and prevalence of skin lesion. 793. resident villagers were surveyed in arsenic poisoning area. The relationship between arsenic concentration and dose in water and prevalence rate was analyzed. The results show that they are positive and sharp correlation. The correction coefficient r = 0.96, and r = 0.638. The dose - effect relationship exist between total arsenic absorb and prevalence rate.更多还原
