摘　　要：目的评价青海省成年牧民砖茶氟摄入水平及潜在的健康风险。方法利用2019—2021年青海省砖茶氟含量监测数据及2015年青海省牧民砖茶消费量专项调查资料,采用简单分布评估方法,评估青海省牧民砖茶氟摄入水平及潜在风险。结果砖茶平均氟含量为464.32 mg/kg,最大值为1206.00 mg/kg,超标率为74.74%(213/285),其中康砖茶超标率最高,为100%(12/12);青海省牧民平均每日砖茶氟摄入量为0.048 mg/kg BW,接近氟的可耐受最高摄入量(UL);高消费人群(P95)平均每日砖茶氟摄入量为0.177 mg/kg BW,是UL的3.1倍;女性消费人群的平均每日砖茶氟摄入量是男性的1.3倍。结论青海省成年牧民饮用的砖茶氟含量较高,长期饮用可能会导致健康风险,特别是高消费人群,应采取有效措施进行控制。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 1206.00 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.
