邯郸市县氟病区集中分布在我市东北平原拗陷地带,涉及16个乡镇,83个自然村,111265人。1981年普查发现该病区83眼井水氟含量均超标(>1.0mg/L)。氟斑牙患者多达83451人,占该区人口75.00％,氟骨症患者659人,占0.59％,危害十分严重。 1984年,打深井51眼,取代和封闭了原超标的水井。为了解改水降氟的效果,1992年我们对原病区现水氟动态进行了普查,现总结如下。 Handan City, fluorosis wards concentrated in the city northeast plains depression, involving 16 towns and villages, 83 villages, 111,265 people. The 1981 census found that the fluorine content of 83 wells in the ward exceeded the standard (> 1.0 mg / L). As many as 83,451 dental fluorosis patients, accounting for 75.00% of the population of the district, skeletal fluorosis patients 659, accounting for 0.59%, the harm is very serious. In 1984, 51 deep wells were drilled to replace and close the wells that exceeded the original standard. In order to understand the effect of water diversion and fluoride reduction, we conducted a general survey of the dynamic status of water and fluoride in the original ward in 1992 and are summarized as follows.
