2000、2001年甘肃省泰安县地方性氟中毒监测结果分析

目的　了解甘肃省秦安县饮水型氟中毒病区改水工程运行情况及其降氟效果 ,用于指导全省地氟病防治。方法　 Dean氏法进行儿童氟斑牙诊断 ,X线拍片检查氟骨症 ,离子选择电极法测定水氟、儿童尿氟含量。结果　 2 0 0 0、2 0 0 1年泰安县儿童氟斑牙检出率分别为 35 .3%和 39.9% ,尿氟含量均值 >1.5 0 mg/L ;成人氟骨症X线检出率为 2 4 % ;两年均有 6 0 %左右的改水工程不能正常运行。结论　饮水型氟中毒病区降氟改水防病效果显著 ,但工程维修、管理不善影响了防病工作。

Analysis on results of national endemic fluorosis surveillance in Tian county Gansu province in 2000,2001

Objective To understand the using state of water improvement to reduce fluoride project and effect of reducing fluoride in drinking-water type fluorosis areas in order to direct the prevention of endemic fluorosis in Gansu province.Methods The dental fluorosis of children was examined with Dean's index and skeletal fluorosis diagnosed with X-ray. Fluoride contents in drinking water and urine were determined with FSIE.Results The detectable rates of the dental fluorosis were 35.3% in 2000 and 39.9% in 2001; the rate of skeletal fluorosis was 24% in 2001. About 60% of water improvement project could not normally be run in 2000,2001.Conclusions Effect of water improvement to reduce fluoride and prevent disease is obvious, but ill management and maintenance affect the effect.
