四川阿壩與內蒙古陳旗磚茶中氟含量的調查 (1)
衛生部飲磚茶型氟中毒專家調查組
摘要目的檢測四川阿壩與內蒙古陳旗磚茶中的氟含量，了解磚茶氟含量水平。方法采用氟離子選擇電極法。結果53份磚茶氟含量均值為748.5mg/kg，其中四川阿壩與內蒙古陳旗的磚茶氟含量均值為741.5mg/kg、756.8mg/kg，二者差異無顯著意義（p>0.05）；水煮法檢測的氟含量占酸浸法的77.1%；磚茶氟含量是其它茶葉的4.4倍；不同環節、不同產地的磚茶氟含量差異無顯著意義（p＞0.05）。結論磚茶氟含量高于其它茶葉，應制訂磚茶氟含量標準。

analysis of fluoride in brick-tea consumed in aba county,
sichuan province and chen county, inner mongolia autonomous region
experts' group of the ministry of public health for epidemiological
survey on fluorosis of drinking brick-tea type
(endemic fluorosis institute, harbin medical university, harbin 150086, china)
abstractobjectivedetermine and understand flouride content in brick tea consumed in aba county, sichuan province and chen county, inner mongolia autonomous region.methodfluoride ion selective electrode method was used. resultmean fluoride content of 53 brick tea samples was 748.5mg/kg, of them 741.5mg/kg in aba and 756.8mg/kg in chen, respectively. there was no significant difference between the fluoride contents of aba brick tea and chen′s (p>0.05). the fluoride content of brick tea infusion treated by water boiling accounted for 77.1% of that treated by acid immersing. fluoride content in brick tea was 4.4 times as much as that in common tea. no significant difference was found in the fluoride contents of brick tea coming from different links and produced areas.conclusionsfluoride content in brick tea is much higher than that in other kinds of tea, so the national standard of fluoride content in brick tea should be worked out.

茶是人們居家訪友最常用的飲品，特別是少數民族在日常生活中離不開茶。飲用高氟茶可導致氟中毒現已得到公認［1～3］。為了解磚茶氟含量水平，以便制訂磚茶氟含量
