samples of market-sell brick tea are analyzed and the average fluoride content is,541.96mg/kg with range from 325.57 to 1139.20 mg/kg。The fluoride content in brick tea varies with the produc-ing area,producing date and variety of brick tea.The degree of old or tender of the original tea leavex and theenvironmental fluoride content have great effect on the fluoride content in brick tea. People who like drinkingbrick tea may take in 4.95 mg/day fluoride in average and 10.40 mg/day in the highest.The average fluoridecontent in 60 samples of drinking brick tea water we tested is 2.81 mg/L and exceeds the standard of the wa-ter fluoride content in the middle fluorosis epidemic area.The mean urinal fluoride content of those who drinkbrick tea is 1.70 mg/L which is one time higher than that(0.79 mg/L)of the normal people who do not drinkbrick tea.So in the conclude we think drinking brick tea can lead the high intake and accumulation of fluoridein body and result in fluorosis.
