寿光市是山东省重点地氟病区之一,自1992年开始,我们在全市进行了饮用水氟含量调查,对查出的高氟村落实了以打深水井为主的降氟改水措施。为了解降氟效果,1998～1999年我站对全市饮水井氟含量进行了复查,并对改水后高氟水原因进行了分析,报告如下:1 材料与方法1·1 采样与水氟测定方法 在平水期对每个村集中供水井
Shouguang City is one of the key fluorosis areas in Shandong Province. Since 1992, we conducted a survey on the fluorine content of drinking water in the whole city and implemented the fluorine-reducing and water-reforming measures for deep-well wells . In order to understand the effect of fluoride reduction, from 1998 to 1999, I observed the fluoride content of drinking water wells in the city and analyzed the causes of high fluoride water after water reforming. The report is as follows: 1 Materials and methods 1.1 Sampling and determination of water fluoride Methods Concentrate water supply wells in each village during the flat-water period
