2002~2005年连云港市降氟改水工程水氟监测

Analysis on water fluoride surveillance of lowing fluoride in drinking water project in Lianyungang,during 2002～2005

目的:了解降氟改水工程后水氟含量动态变化规律。方法:用氟离子选择电极法检测水氟含量。结果:随时间的推移,降氟改水工程的水氟含量、水氟含量超标率均呈现上升趋势。结论:连云港市的病区地貌对水氟含量有一定影响,应持续监测,找出解决方法,保证供水质量。

Objective:To find out dynamic changing laws of water fluoride level after conducting the project of lowing fluoride content in drinking water.Method: Fluoride level in drinking water was examined with F-ion selective electrode method.Result: The trends of water fluoride level and ratio of under-standard of water fluoride level were ascending as time passed.Conclusion: Water fluoride content of endemic fluorosis is affected by physiognomy of Lianyungang.What we should be done is to survey continuously and to find out the solutions so as to guarantee the quality of water supply.
