饮茶摄氟量取决于三个要素: 饮茶方式、茶氟富集量与氟浸出率 ,其中茶氟富集量是首要因素。 茶水含氟量以一泡茶水最高 ,二泡茶水次之 ,三泡及其以后的茶水含氟量急剧下降。 茶叶中富集的氟 ,基本上是水溶性化合物。饮茶过程中约有 42% ～ 86% 的氟溶于茶汤被人体摄入。饮茶摄氟量关系到饮茶与人体健康 ,摄氟量过高 ,会造成氟中毒。
 

The uptaken fluorine amount from drinking tea is affected by three factors: styles of drinking tea , fluorine accumulation in tea and extraction rate of fluorine in tea ,among which fluorine accumulation in tea is the most important factor. Fluorine content in 1st extraction of tea is the highest, fluorine content in 2nd extraction is less, fluorine content in 3rd and the following extractions decrease sharply. Fluorine in tea can almost all dissolve in water. When drinking tea 42% ～ 86% fluorine in tea is uptaken by body. The uptaken fluorine amount from drinking tea is correlated with people′s health, uptaken too much fluorine amount will cause fluorosis.
