[目的]分析林芝地区人群尿氟含量、饮用水和茶中氟的含量与日茶氟摄入量情况的关系,探索人群饮茶与氟中毒的关系。[方法]在林芝地区除墨脱县外,对其余6个县的8～12岁儿童及20岁以上成人尿样及水源和茶水采用离子选择电极法测定氟含量。[结果]8～12岁儿童尿氟含量>1.40 mg/L的占总数的21.6%;成人尿氟含量>1.60 mg/L占总数的42.2%,成人明显高于儿童。饮用水含氟量匀小于国家标准1.0 mg/L,而茶水中各县平均氟含量在3.89 mg/L以上,高于国标近4倍。[结论]从本次检测结果看,随着年龄组的增加,砖茶饮用量越多者体内的氟蓄积也越多,尿氟含量也随之递增。应积极开展对饮茶型氟中毒的防治工作,减轻氟中毒对人体的危害,提高全民的生活质量。
[Objective] To analyze the relationship between urinary fluoride content, fluorine content in drinking water and tea and fluoroquinone intake in Nyingchi area, and to explore the relationship between drinking tea and fluoride poisoning in population. [Method] With the exception of Medog County in Nyingchi Prefecture, the fluoride content of urine samples, water sources and tea in 8 ~ 12 years old and adults over 20 years old in the remaining 6 counties were determined by ion selective electrode method. [Results] The urinary fluoride content> 1.40 mg / L for children aged 8-12 years accounted for 21.6% of the total; the urinary fluoride content for adults> 1.60 mg / L accounted for 42.2% of the total number of adults, which was significantly higher in children than in children. The fluoride content of drinking water is less than the national standard of 1.0 mg / L, while the average fluorine content of tea in all counties is 3.89 mg / L or more, nearly 4 times higher than the national standard. [Conclusion] From the results of this test, with the increase of age group, the more the amount of brick tea drink, the more the body of fluoride accumulation, urinary fluoride content also increases. Should be actively carried out prevention and treatment of tea drinking fluorosis, reduce the hazards of fluoride poisoning on the human body and improve the quality of life of the entire people.
