【摘要】 目的了解病区县及监测点的改水现状及地方性氟中毒病情。方法检测病区县及监测点防氟井使用情况、居民饮水氟含量。采用Dean氏法调查监测点8~12岁儿童氟斑牙患病率;调查监测点16岁以上人群氟骨症患病情况和8~12岁儿童、16岁以上人群尿氟含量。结果病区县79个防氟井中,有29眼(36.71%)完好并可正常使用,其中有20眼(68.97%)饮水氟含量正常。2个监测点饮水氟含量分别为4.78mg/L和0.68mg/L;8~12岁儿童尿氟均值分别为4.53mg/L和1.89mg/L;8~12岁儿童氟斑牙患病率分别为96.88%和33.33%;16岁以上人群氟骨症检出率分别为8.00%和3.67%;氟骨症患者尿氟均值分别为4.39mg/L和2.17mg/L。结论病区县大多数病区饮水氟含量超标,地方性氟中毒防治形势严峻。防氟改水是控制地方性氟中毒的有效方法,应进一步加强。更多还原

【Abstract】 Objective To explore the condition of local fluorosis disease of illness and changing water current state in the disease of area county and monitors . Methods TO check the usage condition of against fluorine well and the fluorine contents of drinking water in area county of disease and the point of guarding . Adopt Mrs. Dean law to monitor morbidity of fluorine speckle tooth in 8 to 12-year-old children, To explore fluorine bone disease diseasedness condition above 16-year-old crowd composes on inquiry monitoring and urinates fluorine contents in reply 8 to 12-year-old children and crowd above 16-year-old . Results In disease’s area county 79’s against fluorine well, 29 using (36.71%) , has among them (68.97%) 20 drinking water fluorines contents is normal. Conclusions In the disease area county, a great of diseases area drinking water fluorine contents go beyond standard , local fluorosis prevention and cure circumstances is austere. prevention fluorine changing water is the sharpening controlling effective local fluorosis method , should be further.更多还原
