【摘要】 目的　了解饮水型氟中毒病区范围及饮茶型氟中毒病区。方法　采用氟电极法测定水氟、茶氟含量 ,用 Dean氏分度法进行儿童氟斑牙诊断。结果　只有阿苏木水氟含量为 (2 .12± 0 .74) m g/ L,其它苏木水氟含量均在正常标准以下 ;奶茶氟含量在 0 .5 5～ 4.1mg/ L 之间 ;砖茶含氟量在 (1.37± 1.2 0 ) mg/ g;儿童氟斑牙检出率超过 30 %的仅有 1个苏木。结论　新巴尔虎左旗如果视为氟中毒病区 ,尚需做深入细致调查研究更多还原

【Abstract】 Objective Understand recent condition of ten drinking water type of endemic fluorosis and drinking tea type of endemic fluorosis.Methods The fluoride content in drinking water and drinking tea were determind with FSIE method.The dental fluorosis of children was examined with Dean’s Index.Results Only the median water fluoride content in Asumu was (2.12±0.74)mg/L,other sumu water fluorsis content under normal level.Milk tea fluoride content was within 0.55~4.1 mg/L.Fluoride content in brick tea was 0.6 mg/g.The dental fluorosis of children detectable rate more than 30% was only one sume.Conclusions If we regard Xinbarhuzuoqi as a endemic fluorosis area,we need careful and deep research.更多还原
