摘要
目的了解内蒙古鄂托克旗地方性氟中毒历史病区饮水氟含量与人群病情现状，科学指导今后防治工作，为制定防治策略提供科学依据。方法2015年，将鄂托克旗100个地方性氟中毒历史病区村作为调查点，了解调查村改水降氟工程进度和运行情况；在已改水村采集1份末梢水水样，未改水村按东、南、西、北、中5个方位各采集1份水样，检测水氟含量。对所有调查村8～12岁儿童进行氟斑牙检查。水氟测定采用《生活饮用水标准检验方法》（GB／T5750．5-2006）；氟斑牙诊断采用《氟斑牙诊断标准》（WS／T208-2011）。结果共调查100个历史病区村，有改水工程39个，改水率为39．00％（39／100）。在39个改水工程中，正常运转率为66．67％（26／39），间歇运转率为15-38％（6／39），报废工程占17．95％（7／39），水氟合格工程占53．85％（21／39）。共检测268份水样，水氟含量平均值为1．39mg／L，范围为0．22～5．57mg／L。61个未改水村，水氟〉1．2mg／L的占68．85％（42／61）。其中水氟〉1．2～2．0mg／L的占49．18％（30／61），覆盖人口数为5231人；水氟〉2．0～4．0mg／L的占18．03％（11／61），覆盖人口数为2326人；水氟〉4．0mg,／L的占1．64％（1／61），覆盖人口数为162人。共检测8—12岁儿童1040人，氟斑牙检出率为9．71％（101／1040），氟斑牙指数为0．18，氟斑牙流行强度为阴性。结论内蒙古鄂托克旗改水降氟工程对儿童氟斑牙预防有一定效果。但水氟超标严重，改水措施有待进一步加强。
Objective To understand the status of the disease in local population and the fluoride content in drinking water in the endemic areas of endemic fluorosis in Etuoke Banner of Inner Mongolia, and to provide a scientific basis for making strategies in prevention and control of the disease. Methods Totally 100 endemic fluorosis villages were selected as survey sites, to study the progress and effect of water-improving and defluoridation projects in Etuoke Banner in 2015. In monitoring villages with improved water, 1 water sample from the tap water was collected to determine the fluoride level, and in water unimproved villages, 1 water sample from each direction of the east, south, west, north and middle of the villages was collected, respectively, to determine fluoride level. Dental fluorosis of children aged 8 to 12 was examined in each village. Water fluoride was tested according to the ＂Standard Testing Methods for Drinking Water＂ （GB/T 5750.5-2006）. Diagnosis of dental fluorosis was based on the ＂Diagnostic Criteria for Dental Fluorosis＂ （WS/T 208-2011）. Results A total of 100 diseased villages were investigate, the water-improving rate was 39.00% （39/100）. Among the 39 water-improving projects, normal operating rate was 66.67% （26/39）, intermittent operating rate was 15.38% （6/39） and scrapped projects accounted for 17.95% （7/39）; the qualified rate of water fluoride projects was 53.85% （21/39）. A total of 268 tap water samples were collected, the mean of water fluoride was 1.39 mg/L, and the range was 0.22 - 5.57 mg/L. In the 61 water- unimproved villages, the water fluoride level 〉 1.2 mg/L in the drinking water accounted for 49.18% （30/61）, covering a population of 5 231 people. The water fluoride level 〉 2.0 - 4.0 mg/L in the drinking water accounted for 18.03% （11/61）, covering a population of 2 326 people; the number of village with water fluoride level 〉 4.0 mg/L was 1, accounted for 1.64% （1/61）, covering a population of 162 people. A total of 1 040
