“氟病”在我国是分布面广、危害极大的一种地方病,仅河北省就有124个县市的570万人处于氟病的威胁之下,现患病人数达160余万,全国约有4500万人饮用高氟水,几乎占全国人口的1/20。邯郸东部平原也是高氟地下水分布区之一,地方性氟中毒涉及十二个县(图1)。该区地质、水文地质条件及水化学特征较为复杂。平面上,全淡区(按本区标准矿化度小于2g/1)地下水中F~-有高有低,咸水区(矿化度大于2 “Fluorosis” in our country is a widely distributed and endangered great endemic disease. Only 5.7 million people in 124 counties and cities in Hebei Province are under the threat of fluorosis, and the number of patients currently suffering is over 1.6 million. The national About 45 million people drink high-fluoride water, accounting for almost 1/20 of the country’s population. The eastern plain of Handan is also one of the high fluoride groundwater areas, with endemic fluorosis involving 12 counties (Figure 1). The geological, hydrogeological and hydrochemistry features in this area are complicated. On the plane, the zone of complete lightness (according to the standard salinity of this zone is less than 2g / 1), groundwater F ~ - has high and low, saltwater zones (salinity greater than 2
