目的 确定贝尔湖附近牧区是否为氟中毒病区以及病情现状与摄氟来源。据此，制定防治地氟病的规划。方法 进行现况典型调查。调查对象为8－12周岁儿童，氟斑牙按Dean氏法诊断。饮水氟、尿氟、奶茶氟均采用氟离子选择电极法测定。结果 氟斑牙检出率：宝东为58．65％，贝尔为66．00％；尿氟含量均值，宝东为6．28mg/L，贝尔为6．56mg/L；饮水氟含量均值：宝东为5．25mg/L，贝尔为4．02mg/L；奶茶氟含量均值：宝东为5．80mg/L，贝尔为5．88mg/L。结论 贝尔湖附近牧区是一个饮水型与饮茶型相混合的氟中毒病区，以饮水型为主。

The state of fluorosis and the sources of fluoride intake near the Beier lake area

Objective To define the area near the Beier lake is the area of fluorosis or not and the state of fluorosis and the sources of fluoride intake.To set up formulated prevention and control programs for fluorosis.Methods Present situation typical investigation was adopted. Dental fluorosis of children was examined by Dean's Index, the fluoride content in the drinking water, the urine of children and the milk tea were determined by fluoride elective ion electrode.Results The prevalence rate of dental fluorosis of children: Baodong was 58.65 %, Beier was 66.00%; the average fluoride content in the urine of children: Baodong was 6.28 mg/L, Beier was 6.56 mg/L; the average fluoride content in the drinking water: Baodong was 5.25 mg/L, Beier was 4.02 mg/L; the average fluoride content in the milk tea: Baodong was 5.80 mg/L, Beier was 5.88 mg/L.Conclusions The area near the Beier lake is a mixed fluorosis area with drinking water type and drinking brick tea type.
