摘要
目的掌握甘肃省地方性氟中毒病区所属生态类型区及高氟水源分布现状，为制订防治策略提供科学依据。方法于2006—2008年，调查项目县（区）村民定居点生态及饮用水源情况。在各项目县（区）病区村开展即时饮用水源水氟筛查，按东、西、南、北、中5个方位选取水源水5份，用氟离子选择电极测定水氟。结果共在45个县进行了筛查，在41个县筛查出超标水样7174份，占29．84％（7174／20241），分布在1524个村，占31．62％（1524／4819），其中28个县有〉2．0mg／L的水样检出，9个县的30个村有〉4．0mg／L的水样检出。按超标水样和有超标水样的村比率从低到高排序，均为甘南高原草原草甸区〈荒漠区〈河西走廊戈壁区〈黄土高原丘陵区〈黄土高原沟壑区。结论不同生态类型区内居民所面临的饮用水问题不同，应合理规划和分类指导地方性氟巾毒的预防控制工作。
Objective To master the status of the distribution of high-fluorine water and ecological districts endemic areas of fluorosis in Gansu Province so as to provide a scientific basis for control strategy. Methods The information on ecology and drinking water sources was surveyed in rural residential areas of the project counties （district）. Five samples of source water were collected from five azimuths of east, west, north, south and center in every endemic village to detect fluoride content and calculate the mean. Water fluoride content was detected by means of fluorides ion selective electrode. Results In 41 counties of the total 45 counties, fluoride contents in 7174 water samples were screened out to be more than 1.0 mg/L and accounted for 29.84% （7174/24 041 ）, which were distributed in 1524 villages, accounting for 31.64% （1524/4819） in water samples. It was found that fluoride contents in water samples in 28 counties were more than 2.0 mg/L and in 30 villages of 9 counties were more than 4.0 mg/L, which were distributed in the hills and valleys of Loess Plateau or the Loess Plateau-gully region. The results showed that the fluoride levels of different areas presented such a sequence as（from low to high） ： the grassland meadow area of Gannan plateau 〈 the desert region 〈 the gobi region of Hexi Corridor 〈 the hills and valleys region of Loess Plateau 〈 the Loess Plateau-gully region. Conclusions Residents in different ecotypic areas of Gansu Province face different drinking water problems, and reasonable planning and guidance should be adopted to prevent and control the endemic fluorosis.
