目的了解平遥县饮水型砷中毒分布及危害状况,探讨砷中毒病区水砷含量与患病率之间的关系。方法对汾河流域氟中毒病区南薛靳等12个村连续居住半年以上的全部居民12 562人进行砷中毒病情普查,并对病区水砷含量进行检测。结果砷中毒患者58人,患病率0.50%,水样砷含量在0.029～0.160mg/L之间,且水砷含量与患病率之间存在高度相关性。结论平遥县的饮水型砷中毒病区村分布于该县汾河流域氟中毒病区,水井含砷量越高砷中毒患病率也越高,建议今后改水降氟除砷要统筹兼顾,加强饮水监测,对新打的深井应将水砷作为必检项目,采取综合有效措施,防控砷中毒发生。
Objective To understand the distribution and hazard status of drinking water type arsenic poisoning in Pingyao County and to explore the relationship between arsenic content and prevalence in arsenism area. Methods A total of 12 562 residents living in more than six months in 12 villages such as Nan Xuejin in Fen Po River Ward were surveyed for arsenicosis, and the arsenic content in the ward was tested. Results 58 cases of arsenic poisoning, the prevalence of 0.50%, arsenic content of water samples between 0.029 ~ 0.160mg / L, and water arsenic content and the prevalence of a high degree of correlation. Conclusions Drinking water type arsenism in Pingyao County is distributed in the fluorosis area of Fenhe River in this county. The higher the arsenic content in water wells, the higher the prevalence of arsenic poisoning. Therefore, Strengthen drinking water monitoring, water deep arsenic should be a test of water as a project, to take comprehensive and effective measures to prevent arsenic poisoning.
