摘要
综述国内外文献 ,砖茶含氟量显著高于一般茶叶 ,有 92 .4 %的砖茶样品含氟量在 5 0 0～ 80 0 m g/ kg范围内。砖茶氟摄入量愈高 ,氟斑牙和氟骨症愈重 ,但受营养因素影响。饮砖茶水的少数民族 ,每人每日茶氟摄入6～ 16 m g,平均为 12 mg左右。蒙族每人每日摄砖茶氟 4 .19mg,可不发生氟骨症 ,6 .6 2 m g可发生 度氟骨症 ,大多数少数民族每人每年饮用砖茶 5 kg,如果砖茶含氟量限制在 30 0 m g/ kg以下 ,平均每人每日摄氟量不超过4 .1m g。
Reviewing data in the world, we can see that the fluoride content of brick tea is greatly higher than that of common teas. Investigations showed that the fluoride content of brick tea samples of 92.4% varied from 500 to 800 mg/kg. The more fluoride of brick tea is ingested, the more serious dental fluorosis and skeleton fluorosis is. But this can be affected by nutrition factors. Each person of minority drinking brick tea water ingested 6~16 mg fluoride per day, and the average was around 12 mg. Results indicated that in Mongolia, skeleton fluorosis could not be caused by 4.19 mg fluoride intake a day due to drinking tea water, but one degree skeleton fluorosis occurred by intaking 6.62 mg fluoride. Each person of most minority consumes 5 kg brick tea every year. If the fluoride content of brick tea was restricted under 300 mg/kg, the average fluoride intake of one person a day would be 4.1 mg, which may prevent most people from suffering skeleton fluorosis.
