广东省水型高氟病区改水效果分析

An effect analysis on lowering fluoride content at endemic fluorosis areas, Guangdong province

目的 :通过现场调查了解广东省水型高氟区经过十几年改水工作之后 ,取得什么样的效果 ,存在什么问题 ,根据现状分析 ,为今后改水工作的完善提出合理化建议。方法 :现场流行病学与实验室检测相结合 ,数据经 SAS统计软件分析。结果 :广东省高氟病区改水工作经过各级政府的重视和努力 ,已取得显著的效果 ,改水后水氟含量符合国家标准 ,氟斑牙患病率有显著下降 ,但目前仍遗留少部分地区未改水 ,早期改水的某些村落因规模太小或设施陈旧而未能满足现在的需要。结论 :广东省水型氟病区改水已取得阶段性成果 ,全面取得决定性胜利仍需努力。

Objective Through investigation at endemic fluorosis areas to assess the effect of the lowering fluoride content in drinking water as well as the current condition including the water quality and dental fluorosis prevalence in the children. At the same time, suggestion for the continue work is made.Methods Combination of field epidemiology and experiment test was conducted and the data were dealt with SAS system. Results Significant results have been taken in the past years for improving the drinking water quality and reducing the prevalence of dental fluorosis in the children. But some areas remain original condition and small parts of the villages which had conducted water improved face the difficulties for changing the facilities and tubes. Conclusion Effect is significant for the past years' work in improving the quality in drinking water in the endemic fluorosis areas. Further task remain to be done for the whole success. Difficulties of lowering fluoride in water has been conducted in high fluoride areas in Guangdong province for more than 10 years. The results were remarkable and showed that behind the success, we also faced some problems. These should be considered in future lowering fluoride in water in high fluoride areas in Guangdong province.
