目的调查分析氟中毒的流行病学特征。方法选择内蒙古赤峰市巴林左旗伴有氟中毒危害的地区作为研究对象,于2015年4月20日至6月10日调查当地的水氟含量及氟斑牙和氟骨症的发病情况。结果防氟改水工程水质监测示水氟含量变动范围不大,水氟含量在1.2mg/L以下的工程井有18处,水氟含量在1.2mg/L以上的工程井有21处。全旗共调查8~12岁儿童400人,其中正常245人,氟斑牙可疑110人,氟斑牙极轻33人,氟斑牙轻度12人,氟斑牙指数0.28,氟斑牙患病率11.25%。全旗共调查成年人400人,其中正常187人,氟斑牙可疑97人,氟斑牙极轻69人,氟斑牙轻度38人,氟斑牙中度9人,氟斑牙指数0.55,氟斑牙患病率29%。没有新发的氟骨症病人。结论巴林左旗氟中毒情况虽较以往有所好转,但目前仍未达到控制标准,仍需继续加强防控。
Objective To investigate the epidemiological characteristics of fluorosis. Methods The areas with the risk of fluorosis in Balinzuo Banner, Chifeng City, Inner Mongolia were selected as the research objects. The fluoride content in the water and the incidence of dental fluorosis and skeletal fluorosis were investigated from April 20 to June 10, 2015. Results Water quality monitoring of anti-fluoride water diversion project showed a small range of fluorine content change, 18 engineering water wells with water fluoride content below 1.2mg / L and 21 engineering water water fluoride contents above 1.2mg / L. The flag of a total of 400 children aged 8 to 12 years, of whom 245 were normal, suspicious dental fluorosis 110 people, 33 were extremely light dental fluorosis, 12 were mild dental fluorosis, dental fluorosis index 0.28, dental fluorosis The rate of 11.25%. The flag of a total of 400 adults surveyed, of which 187 were normal, 97 suspicious dental fluorosis, dental fluorosis of 69 very light, mild dental fluorosis 38, dental fluorosis moderate 9, dental fluorosis index 0.55 , The prevalence of dental fluorosis 29%. No new skeletal fluorosis patients. Conclusion Although the situation of fluorine poisoning in Bahrain left flag has improved somewhat in the past, the control standard has not yet been reached and the prevention and control still need to be strengthened.
