目的了解内蒙古包头市土右旗饮水含砷量及地方性砷中毒病情防治现状.方法 2010年,对包头市土右旗7个自然村(缸房营、老虎尧、石老丈、油房营、王老四、大井、小井)进行砷中毒病情监测,采取入户调查的方式筛查砷中毒病人,砷中毒诊断采用《地方性砷中毒诊断标准》(WS/T 211-2001).调查萨拉齐自来水公司、毛岱自来水公司和老虎尧改水工程3个改水工程运行情况.在每个改水工程和监测村采集枯水期和丰水期水样各2份,测定水砷,水砷测定采用二乙氨基二硫代甲酸银分光光度法(WS/T28-1996).结果 3个改水工程均正常运行,萨拉齐自来水公司、毛岱自来水公司水砷均＜ 0.01 mg/L,符合饮用水安全标准；老虎尧改水工程水砷为0.053 mg/L,高于饮用水安全标准.7个村已全部改水,老虎尧村水砷为0.052 mg/L,其余6个村水砷均＜ 0.05 mg/L.共监测2095人,检出可疑病例6例,轻度病例14例,中度病例4例,重度病例10例；无新发病例出现.砷中毒病人的年龄主要集中在40 ～ 70岁.结论包头市土右旗部分村饮水含砷量仍然超标,但未在砷中毒病区发现新的砷中毒病人.

Objective To understand the arsenic level in drinking water and the current situation in prevention and control of endemic arsenic poisoning in Tuyouqi,Baotou of Inner Mongolia.Methods Through door-to-door survey,we selected patients with arsenic poisoning in order to monitor the arsenic poisoning condition of seven villages(Gangfangying,Laohuyao,Shilaozhang,Youfangying,Wanglaosi,Dajing and Xiaojing) in Tuyouqi,Baotou in 2010,and the disease was diagnosed based on "Standard of Diagnosis for Endemic Arsenism"(WS/T 211-2001).We also investigated the operation of Salaqi Water Company,Maodai Water Company and the Laohuyao water improvement project.We collected two samples per place in both low water period and high water period to measure water arsenic with silver diethyldithiocarbamate spectrophotometry(WS/T 28-1996).Results Three water improving projects were operating in normal conditions.Water arsenic in Salaqi Water Company and Maodai Water Company was level less than 0.01 mg/L,which met the National Safety Standards of drinking water with arsenic.Water arsenic in Laohuyao improvement project was 0.053 mg/L,which was higher than the drinking water safety standards.The seven villages in Tuyouqi had improved their water conditions.Among them,the arsenic level in Laohuyao was 0.052 mg/L,and the remaining six villages were ＜ 0.05 mg/L.There were 6 suspected cases,14 mild cases,4 moderate cases and 10 severe cases of the 2095 people monitored and no new cases found.The age of patients with arsenic poisoning was in the range of 40 to 70.Conclusions The monitoring results show that drinking water arsenic level in some villages in Tuyouqi is still excessive,but no new arsenic poisoning patients in arsenic poisoning areas are found.
