摘要
目的调查青海省内流通的砖茶品种、产地、氟含量,以及人群砖茶饮用情况,为实施饮茶型地方性氟中毒(简称地氟病)控制措施提供依据。方法2019年4-11月,根据历史资料,对青海省39个县(市、区,简称县)有饮用砖茶习惯的3066个行政村,每个村抽取10户家庭,调查每户家庭人口学资料及砖茶饮用情况,采集砖茶样本测定氟含量,计算>16岁人口日人均茶氟摄入量。结果共采集砖茶样本31067份,以茯砖为主,占全部砖茶的89.97%(27952/31067),康砖占5.12%(1592/31067),青砖占2.29%(710/31067),黑砖占1.85%(574/31067),金尖、花砖、黑毛等其他砖茶占0.77%(239/31067)。全省居民饮用的砖茶来自523种品牌,其中产地为湖南省的品牌有410种,产地为四川省的品牌有26种,产地为湖北省的品牌有11种,产地为河南等其他省份的品牌共有76种。砖茶氟含量均值为646.1 mg/kg,范围为40.0~2295.0 mg/kg,氟含量≤300 mg/kg的砖茶占全部样本的7.80%(2422/31067);全省>16岁人口年人均砖茶消耗量为1.09(0.35~7.40)kg,日人均茶氟摄入量为1.93(0.39~18.64)mg;日人均茶氟摄入量超过国家标准(3.5 mg)的有15个县、486个行政村。结论青海省流通的砖茶以茯砖为主,氟含量较高,对人群危害严重,应尽快采取有效防控措施。
Objective To find out the variety,producing area,fluorine content of brick tea in Qinghai Province,and the drinking situation of brick tea among people,so as to provide basis for preventing and curing endemic fluorosis of drinking tea type.Methods From April to November 2019,according to historical data,in 3066 administrative villages in 39 counties(cities,districts,hereinafter referred to as counties)in Qinghai Province that had the habit of drinking brick tea,10 families were randomly selected from each village to investigate the demographic data of each family and the drinking situation of brick tea,to collect brick tea samples to determine the fluorine content,and to calculate the daily average brick tea fluorine intake of the population>16 years old.Results A total of 31067 brick tea samples were collected.The main brick tea consumed by the residents in the whole province was Fu brick tea,accounting for 89.97%(27952/31067),followed by Kang brick tea[5.12%(1592/31067)],Green brick tea[2.29%(710/31067)],Black brick tea[1.85%(574/31067)],and golden tip,mosaic,black wool and other brick tea[0.77%(239/31067)].There were 523 brands of brick tea in circulation in the province,among which there were 410 brands produced in Hunan Province,26 brands in Sichuan Province,11 brands in Hubei Province,and 76 brands in Henan Province and other provinces.The average content of fluorine in brick tea was 646.1 mg/kg,which ranged from 40.0 to 2295.0 mg/kg.Brick tea with fluorine content≤300 mg/kg accounted for 7.80%(2422/31067)of all samples.The annual average consumption of brick tea by population>16 years old was 1.09(0.35-7.40)kg,and the daily average brick tea fluorine intake was 1.93(0.39-18.64)mg.There were 15 counties and 486 administrative villages in which the daily average brick tea fluorine intake exceeded the national standard(3.5 mg).Conclusion The main brick tea in circulation in Qinghai Province is Fu brick tea,which has high fluorine content and is harmful to people,and prevention and control measures should be taken as soon as possible.
