摘要
研究表明，氟高值区域主要分布在茭道—武义一线两侧，氟含量高值区呈北东风条带状展布，与萤石矿带吻合；各地层氟丰度不一，矿区附近较高；该地区降水量较大，酸性红壤土、重碳酸钙型为主的水化学类型限制了高氟地表环境的形成，而盆地结构、人为污染加剧了地表水氟丰度；高氟环境污染了水体、土壤及植物，并引起地方性氟病；地方性氟病等是由于饮用含氟水引起的，改水降氟是控制地氟病的有效方法。
Research showed that high fluorine areas were distributed mainly along the Jiaodao_Wuyi line in a form of north_to_east wind strip, which coincided with the fluorite mineral belt. The content of fluorine varied with stratums and became much higher near the fluorine mines. High precipitation, brown soil and calcium bicarbonated Water restricted the formation of a high fluorine surface environment. But the geographic structure of a basin and the artificial pollution resulted in an increase in fluorine in surface water in this area. Water, soil and plants were polluted. Local fluorine diseases resulted from drinking water containing high fluorine.Improving the water quality by reducing its fluorine content would be an effective method to control diseases caused by fluorine.
