湖北省建始县罗家公社与茶园公社相距约25公里。罗家公社海拔500多公尺,历来以烧石煤作燃料:茶园公社海拔700公尺,以前长期烧柴,近3～5年逐渐改为烧优质煤。1982年6月及1984年8月,我们先后调查了罗家3个生产队、茶园2个生产队地氟病流行病学及患病情况。罗家氟斑牙的患病率为93.4%,茶园为0%。据测两地饮水含氟量均低于国家所规定的卫生标准。罗家粮食、蔬菜、空气的含氟量超过国家标准,而茶园除玉米(干样)的含氟量略微高一点外,其他均在规定的范围之内。
Jianshi County, Hubei Province Luo commune and Tea Garden commune about 25 kilometers apart. Luo commune elevation of 500 meters, has always been to burn stone coal as fuel: Tea Park commune 700 meters above sea level, before long-term firewood, nearly 3 to 5 years gradually changed to burn high-quality coal. In June 1982 and August 1984, we successively investigated the epidemiology and prevalence of fluorine in three production teams in Luo and two production teams in the tea plantation. Luo dental fluorosis prevalence rate of 93.4%, 0% of the tea garden. It is reported that both drinking water fluorine content is lower than the national health standards. Luo food, vegetables, air fluoride content exceeds the national standard, while the tea plant in addition to corn (dry) fluorine content slightly higher, the other are within the scope of the provisions.
