目的观察不含添加剂低氟砖茶预防饮茶型氟中毒效果。方法采用含氟量<300 mg/kg不含添加剂低氟砖茶,选择水含氟量1.2 mg/L以下、有饮茶习惯、无工业污染的1个乡(镇)为预防试点。通过居民预防实验前后砖茶、奶茶、尿含氟量检测及经砖茶进入机体日摄氟量,评价不含添加剂低氟砖茶预防饮茶型氟中毒效果。结果饮用低氟砖茶前、饮茶后6、18个月居民奶茶含氟量检测结果分别是(4.38±2.43)、(0.60±0.24)、(0.83±0.37)mg/L;尿含氟量分别是(3.17±1.97)、(1.42±0.81)、(1.55±0.8)mg/L。居民饮用普通高氟砖茶日摄氟量10.26 mg/d,饮用低氟砖茶6、18个月日摄氟量分别是3.23、3.18 mg/d。结论饮用不含添加剂低氟砖茶,可使奶茶氟达到国家饮用水含氟量标椎,经砖茶制品进入机体日摄氟量在国家允许摄入量3.5 mg以内。尿氟显著下降(P<0.01),长期饮用不含添加剂低氟砖茶是预防饮茶型氟中毒的有效方法。
Objective To observe the effect of drinking fluoride-free brick tea without fluoride poisoning. Methods One pilot town (town) containing less than 300 mg / kg of low-fluoride brick tea without additives and a water content of less than 1.2 mg / L, drinking habits and no industrial pollution was used as a preventive pilot. Before and after residents’ prevention experiment, the content of fluorine in brick tea, tea and urine before and after the experiment was tested, and the amount of fluoride taken into the body by brick tea was evaluated. The effect of fluoride-free brick tea without additives on prevention of drinking-type fluorosis was evaluated. Results Before drinking tea with low-carbon brick, the test results of fluoride content in tea milk tea were (4.38 ± 2.43), (0.60 ± 0.24) and (0.83 ± 0.37) mg / L, respectively, (3.17 ± 1.97), (1.42 ± 0.81) and (1.55 ± 0.8) mg / L, respectively. Residents drinking ordinary high-fluoride brick tea daily fluoride intake of 10.26 mg / d, drinking low-fluoride brick tea 6, 18-month fluoride intake were 3.23,3.18 mg / d. Conclusion Drinking low-carbon brick without additives, can make the milk tea fluoride reach the national standard of drinking water fluoride, the amount of fluoride intake of brick tea products into the body in the national allowable intake of 3.5 mg. Urine fluoride decreased significantly (P <0.01), long-term consumption of additives without low-fluoride brick tea is an effective way to prevent drinking-type fluoride poisoning.
