目的了解建阳市氟中毒病区的病情和防氟改水设施的使用情况,为制定地氟病防治策略提供科学依据。方法调查病区8～12岁儿童氟斑牙患病情况,8～12岁儿童尿中氟含量,16岁以上成人临床氟骨症患病调查,病区改水前后居民户饮用水中氟含量,病区改水工程运转情况。结果地氟病区8～12岁人群中未发现氟斑牙,尿氟均值为0.79mg/L,但仍有个别儿童尿氟较高。16岁以上成人临床氟骨症检出率为19.72%。新坪、留田病区改水工程运转良好,松原病区村原改水工程已损毁,村民饮用山泉水、井水及河水,部分井水超标,筛查村未发现高氟水。结论被调查的高氟病区各项指标比改水前有了很大的改善,达到地方性氟中毒病区控制标准,高氟病区村降氟改水措施较巩固,也进一步证实饮水型氟中毒实施改水措施的干预效果,为巩固防治成果需有维修资金和完善的政策法规。
Objective To understand the condition of fluoride poisoning ward in Jianyang City and the use of anti-fluoride water diversion facilities, so as to provide a scientific basis for the prevention and control strategies of earth-flu disease. Methods The prevalence of dental fluorosis in children aged 8 ~ 12 years, the urinary fluoride in children aged 8 ~ 12 and the clinical skeletal fluorosis in adults over 16 years of age were investigated. The fluoride content in drinking water Ward water diversion project operation. Results There was no dental fluorosis in the population of 8 ~ 12 years old in the endemic fluorosis area. The urinary fluoride average was 0.79 mg / L, but there was still a high urinary fluoride in some children. Clinical skeletal fluorosis was detected in 19.72% of adults over 16 years old. Xinping, Retiring ward water works well, Songyuan ward village original water project has been damaged, the villagers drink mountain spring water, well water and river water, some well water exceeded the screening village found no high-fluorine water. Conclusion The indicators of high fluoride area under investigation have been greatly improved compared with that before water change, reaching the control standard of endemic fluorosis area, and the measures to reduce water and fluoride in high-fluorine area are more solidified, which further confirms that drinking water type Fluorosis poisoning measures to implement the intervention effect, in order to consolidate the prevention and control of the need for maintenance funds and improve the policies and regulations.
