Objective To evaluate the intake level of fluoride and potential health risks for herdsmen in Qinghai province.Methods The monitoring data of fluoride content in brick tea from 2019 to 2021 and the data of brick tea consumption by herdsmen in 2015 were used. Based on the deterministic assessment model， the daily intake of fluoride from brick tea by herdsmen was calculated.Results The average fluorine content of brick tea was 464.32 mg/kg， the maximum was 1 206.00 mg/kg， and the over standard rate was 74.74% （213/285）， among which the over standard rate of Kang brick tea was the highest （100%， 12/12）. The average intake level of fluoride was 0.048 mg/kg BW per day， which was close to the tolerable upper intake levels （UL）. The daily fluoride intake of high-consumption group （P95） was 0.177 mg/ kg BW， which was 3.1 times that of UL. The average daily intake of fluoride from brick tea by female consumers was 1.3 times that of men.Conclusion The concentration of fluoride in brick tea was high， and fluoride might cause health risk to tea drinkers especially for high-consumption groups. Some effective measures should be taken to solve this problem.
