目的掌握内蒙古地方性氟中毒(地氟病)病区改水后病情的消长情况,为今后地氟病的防治工作提供科学的依据。方法调查监测点8～12岁儿童氟斑牙患病情况,对监测点井水、居民户饮用水及8～12岁儿童尿样中的氟进行检测。结果2002、2003年度土左旗监测的100个改水井水氟含量合格率分别为97%和98%;监测村2002、2003年度8～12岁儿童氟斑牙检出率分别为54.04%和64.00%,氟斑牙指数分别为1.00和1.02;2002、2003年度8～12岁儿童尿氟几何均数均在正常水平,分别为1.00和1.20mg/L;监测村2年度居民家中饮水氟均为0.36mg/L。结论对于饮水型地方性氟中毒病区,改换水源是最好的预防手段。
Objective To grasp the growth and decline of the disease in the endemic fluorosis (Fluorosis) endemic area in Inner Mongolia, and to provide a scientific basis for future prevention and treatment of fluorosis. Methods The prevalence of dental fluorosis in children aged 8 ~ 12 years was surveyed, and the urinary fluoride in well water, household drinking water and children aged 8 ~ 12 years were monitored. Results The qualified rates of fluoride content in 100 wells for water diversion in 2002 and 2003 were 97% and 98%, respectively. The detection rates of dental fluorosis in children aged 8 ~ 12 in 2002 and 2003 were 54.04% and 64.00, respectively %, Dental fluorosis index were 1.00 and 1.02; 2002, 2003, 8 to 12-year-old children urinary fluoride geometric mean were at normal levels, respectively, 1.00 and 1.20mg / L; 0.36 mg / L. Conclusion For drinking water endemic fluorosis area, changing the water source is the best preventive measure.
