摘要
[目的]了解锡林浩特市牧区居民生活饮用水氟化物含量,掌握牧区饮水型氟中毒(地氟病)病区高氟水分布情况,为牧区饮水安全工程项目提供依据。[方法]2007年9月,对锡林浩特市牧区1个镇、2个苏木、4个国有农牧场的生活饮用水(井水)测定氟化物含量。[结果]合计检测水样1 469份,氟化物含量≤1.2 mg/L的716份,合格率为48.74%;>1.2 mg/L的753份,超标率为51.26%,其中达到地氟病轻病区的占总水样的32.27%,达到中病区的占16.27%,达到重病区的占2.72%。氟化物含量超标率,南部区(693份)为22.66%,北部区(776份)为76.80%(P<0.01)。[结论]锡林浩特市牧区饮用水氟化物含量超标率很高,地氟病病区分布较广泛。
[Objective]To understand the content of fluoride in drinking water in pastoral area of Xilinhaote city,grasp the distribution of high fluoride in drinking water in fluorosis prevalence area,provide scientific basis for the program of safe drinking water.[Methods]Drinking water samples collected from 1 town,2 Sumu and 4 national owned pasture lands in Xilinhaote were tested for the content of fluoride in Sep,2007.[Results]Of the 1 469 water samples tested,the content of fluoride≤1.2 mg/L in 716 samples,the qualified rate was 48.745.while the content 〉1.2 mg/L in 753 samples,51.26% of them were over the standard.32.27%,16.27% and 2.72% of the water samples tested for fluoride can meet the standard of slight,moderate and serious fluorosis.22.66%（693） and 76.80%（776） of the water samples collected from the South and North area were over the standard（P〈0.01）.[Conclusion]The super-standard rate of the content of fluoride in drinking water in Xilinhaote city was high,the prevalence of fluorosis was widely.
