【摘要】 使用F离子选择电极法 ,对西藏不同地貌、生态特征的藏族人群居住区进行了水、土壤、燃料、粮食、食品、蔬菜、茶的F含量测定 .西藏的水F含量均数为 0 .0 6mg·L-1,土壤可溶性F 0 .45mg·kg-1,主要燃料F含量0 .10mg·kg-1,主要粮食、食品以及蔬菜的F含量 0 .0 6～ 0 .33mg·kg-1,用砖茶调制的酥油茶和糌粑F含量达3 .0 9mg·L-1和 3 .6 1mg·kg-1,产自四川、云南的砖茶水溶性F含量达到 5 33 .89～ 6 17.32mg·kg-1,可以认为 ,西藏有可能是砖茶型F中毒的流行区 .更多还原

【Abstract】 The concentration of fluorine in water, soil, fuel, food, vegetable and tea in Tibetan habitats with different environmental characteristic were measured by ion specific electrode potentiometer.The results showed that the fluorine concentration in water, soil, fuel, food vegetable,butter tea and Zanba both of them were made from brick teas was 0.06 mg·L -1 , 0.45mg·kg -1 , 0.10mg·kg -1 ,0.06～0.33mg·kg -1 ,3.09mg·L -1 and 3.61mg·kg -1 ,respectively. The water soluble fluorine content in brick tea which came from Sichuan and Yunnan Provinces reached up to 533.89～617.32 mg·kg -1 . It is suggested that drinking brick tea may induce fluorosis in Tibetan habitats.更多还原
