目的了解农十三师维吾尔、哈萨克族农牧民氟中毒水平与天然饮用水、与饮用茯砖茶水之间的关系。方法入户检查该人群氟斑牙,检测其尿氟及该区饮用水氟,了解其茯砖茶年消费情况,进行茯砖茶煮沸氟溶出量模拟试验。结果5个团场维、哈族农牧民氟斑牙患病率30.00%~73.27%,当地饮水含氟量0.20~0.46 mg/L,2~3月平均每人每日饮茯茶水1.3~2.3 L,此期间尿氟几何均值为1.80~2.64 mg/L,2 L天然水中加5.0~20.0 g茯砖茶煮沸5 m in后含氟量为3.45~15.72 mg/L。结论农十三师维、哈族农牧民氟中毒水平与饮用茯砖茶水密切相关。
Objective To understand the relationship between fluorine poisoning levels of the 13th Division of Uighur and Kazak farmers in Heilongjiang Province, natural drinking water and drinking Fuzhuan tea. Methods To examine the population of dental fluorosis, and to test its urinary fluoride and fluoride in drinking water in this area. To understand the consumption of Fuzhuan tea in the year and carry out the simulation test of fluoridation of Fuzhuan tea. Results The prevalence of dental fluorosis was between 30.00% ~ 73.27% in local communities and between Ha’er ethnic groups and in the local drinking water. The fluoride content in local drinking water was 0.20 ~ 0.46 mg / L, 2.3 L, the geometric mean of urinary fluoride during this period was 1.80 ~ 2.64 mg / L, and the content of fluorine in the 2 L natural water plus 5.0 ~ 20.0 g Fuzhuan brick after boiling for 5 mins was 3.45 ~ 15.72 mg / L. Conclusions The level of fluoride poisoning in peasants and herdsmen farmers and farmers is closely related to drinking Fuzhuan brick tea.
