中国南安市地氟病区饮用水氟调查研究

INVESTIGATION STUDY ON THE FLUORINE OF DRINKING WATER IN ENDEMIC FLUOROSIS REGIONS IN NANAN CITY.

为掌握南安市三个地氟病区饮用水氟状况，作者对英都石山田洋、洪梅山溪典当和罗东罗溪后茂三地区３２口井、２个泉眼、１个溪水样进行氟含量检测。结果：超过饮用水氟国家标准ＧＢ水样５份，超标率１４．２８％（５／３５），选符合饮用水国家标准且水量充足的２个泉眼和１个溪水作为改水降氟的饮用水源。

o master the fluorine state of drinking water of three endemic fluorosis regions,the fluorine contents of 32 wells water,two springs water and one brook water were examined by us at Tianyang Shishan Yingdu,Diandang Shanxi Hongmei and Houmao Louxi Loudong in Nanan City Fujian P.R.of China.The results were that the five water samples surpassed the national standard of the fluorine of drinking water.The rate of surpassing the national standard of the fluorine was 1428%(5/35).The two springs and one brook accorded with the national standard of drinking water and full of water were selected as the water sources of changing water to descend fluorine.
