地方性氟中毒是贵州分布较广,危害最为严重的地方病。从环境角度出发,深入研究环境对地方性氟中毒的影响,对揭示其病因与防治措施有着重要的作用。 一、地氟病的形成与分布 氟是一种与人体健康关系密切的化学元素,人们一般通过饮食摄入氟,当氟不足时易患龋齿,过多时引起氟中毒。人体每天适宜摄入量1—2毫克,最高允许限度3—4毫克。饮水氟适宜标准为0.5—1.0毫克/升,超过1毫克/升将出现大量氟斑牙患者,超过3毫克/升时,出现氟骨症患者。
Endemic fluorosis is a widely distributed and hardest-hit endemic disease in Guizhou. From the environmental point of view, in-depth study of the impact of environmental fluorosis on the ground, to reveal its causes and prevention and treatment measures play an important role. First, the formation and distribution of endemic fluorosis Fluoride is a chemical element closely related to human health, people generally through the diet of fluoride, when fluoride is insufficient susceptible to dental caries, too much cause fluorosis. The body suitable daily intake of 1-2 mg, the maximum allowable limit of 3-4 mg. Fluoride standard for drinking water 0.5-1.0 mg / l, more than 1 mg / l will appear a large number of dental fluorosis patients, more than 3 mg / l, there skeletal fluorosis patients.
