摘要
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。
Objectives To investigate the condition of endemic fluorosis after water improvement and provide scientific basis for prevention and treatment in the coming days. Methods Dental fluorosis and urine fluoride in children aged 8 - 12 years were detected, fluoride in well water and household drinking water was surveyed. Results In 2002 and 2003, 97% and 98% of the 100 wells that had been improved in Tumotezuo banner met the qualification standard, the detected rate of dental fluorosis in children aged 8 - 12 was 54.04% and 64.00%, dental fluorosis exponential was 1.00 and 1.02,respectively in 2002 and 2003. The geometric average of the urine fluoride of 8 - 12 years old children was within the normal range of 1.00, 1.20 mg/L;the fluoride concentration in drinking water kept same as 0.36 mg/L during the two years. Conclusions Changing drinking water source is the best way to control water-type endemic fluorosis.
