摘要
在盛产萤石的武义盆地，岩层中氟丰度为０．００５％～０．０８９％，生态水源含氟均值：地表水为０．２１ｍｇ／Ｌ，第四系孔隙水为０．２７７ｍｇ／Ｌ，否定了以往认为该盆地为高氟区的观点。建国以来，该区未发现氟骨症患者。患氟斑牙者达３０％以上共７个村，皆因饮用高氟构造裂隙水所致。工厂排污导致的叠加氟污染危害较大，应引起重视。
There is plenty of fluorite in the Wuyi basin. The abundance of F is 0. 005%～0. 089%and the average value of F in ecological water resources is 0. 21mg/L in surface water and 0. 277 mg/L in the Quaternary pore water. This refutes the earlier viewpoint that F content is high in this bssin. There are 7 villages in which more than 30% persons have fluorosis in the whole county. This is because the drinking water there is a kind of structural fissure water containing high F. And the unloadings from the factories cause great detriment of superposed F pollution.
