目的了解饮用高氟砖茶对居民身体健康的危害,掌握饮茶型氟中毒的地区及人群分布情况。方法 8~12岁儿童采用Dean氏法进行氟斑牙诊断;成人氟骨症的调查随机采集成人即时尿液及X线诊断(WS192-2008);砖茶氟含量测定依据《砖茶氟含量》(GB19965-2005)。结果和布克赛尔县每年消耗茶叶32吨,氟含量范围在100~962 mg/kg,均值为608.28 mg/kg,茶水氟含量平均值为1.21 mg/L。65.12%的居民有饮用砖茶的习惯,饮茶是人体摄取氟的重要途径。过量摄入氟是引起氟病的原因,尤其是成人尿液中氟含量显著高于儿童。8~12岁儿童氟斑牙检出率为22.67%,成人氟骨症患病率为11.84%,居民体内氟已经造成了蓄积。结论和布克赛尔蒙古自治县存在饮茶型氟中毒病区。
Objective To understand the hazards of drinking high-fluoride brick tea to the health of residents and to find out the distribution of drinking-fluorosis area and population. Methods Eight to 12-year-old children were diagnosed with dental fluorosis by Dean’s method. Adult fluorosis was randomly collected from adult patients with urine and X-ray diagnosis (WS192-2008). The determination of fluoride content in brick tea was based on the content of fluorine in brick tea (GB19965 -2005). As a result, the annual consumption of 32 tons of tea leaves in Boxelle County ranged from 100 to 962 mg / kg, with an average of 608.28 mg / kg and an average of 1.21 mg / L for tea. 65.12% of residents have the habit of drinking brick tea, tea drinking is an important way of human intake of fluorine. Excessive intake of fluoride is the cause of fluoride disease, especially in adult urine fluoride was significantly higher than children. The detection rate of dental fluorosis in children aged 8 ~ 12 was 22.67%. The prevalence of osteofluorosis in adults was 11.84%. The fluorine in residents had caused the accumulation of fluoride. Conclusions There is drinking-tea type fluorosis area in Mongolian Autonomous County of Bouquex.
