目的了解泉州市饮水型氟中毒病区改水降氟防治效果及健康促进情况,为饮水型氟中毒防治提供依据。方法参照WS/T 90-1996《改水降氟措施效果评价标准》和《地方性氟中毒防治手册》,监测分析全市28个地方性氟中毒病区村的水氟含量及氟斑牙的发病情况。结果全市4县(市、区)共监测28个病区村27个改水工程54份水样,水氟合格率为92.6%(50/54),其中安溪县有4份水氟>1.0mg/L;8～12岁学生氟斑牙患病率为16.6%(57/343),氟斑牙指数0.34,洛江区、南安市、永春县和安溪县患病率分别为11.1%、20.0%、6.3%和20.4%。结论 4县(市、区)在饮水型氟中毒的控制上均取得明显成效,但个别病区村在改水工程管理和维护存在问题,应加强监管。
Objective To understand the prevention and cure of water and fluoride in drinking water-type fluorosis area of Quanzhou and its health promotion, so as to provide basis for prevention and control of drinking-water fluorosis. Methods According to WS / T 90-1996 “Evaluation Criteria of Water Fluoride Reduction Measures” and “Handbook of Prevention and Control of Local Fluorosis”, the fluoride content in water and the incidence of dental fluorosis in 28 endemic fluorosis areas in the city were monitored and analyzed Happening. Results A total of 54 water samples from 27 water diversion projects in 28 ward villages were monitored in 4 counties (cities and districts) in the whole city. The passing rate of water fluorine was 92.6% (50/54). There were 4 water fluoride> 1.0mg / L; prevalence rate of dental fluorosis in children aged 8-12 was 16.6% (57/343), dental fluorosis index was 0.34, prevalence rates in Luojiang District, Nan’an City, Yongchun County and Anxi County were 11.1% and 20.0 %, 6.3% and 20.4%. Conclusion Four counties (cities and districts) have achieved remarkable results in the control of drinking water fluorosis. However, the problems in the management and maintenance of water diversion project in some ward areas should be strengthened and supervision should be strengthened.
