氟及其化合物在工农业生产中的应用是十分广泛的,诸如电解铝、冶金、氢氟酸、氟化盐、磷肥、玻璃和化学工业及农药杀虫剂等生产过程中,工人多有氟的接触。机体长时期摄入较多的氟及其化合物将导致氟骨症,其X线表现以骨质硬化、骨密度增高、韧带钙化和肌腱附着处钙化为主,已为大家所熟知。晚期病例由于其在临床及X线上的特征性表现,诊断并不困难。国外有报导氟作业工人在不良劳动条件下,两年多即可发病,十年已经发展到晚期。在我国无产阶级专政条件下,由于各级党 Fluorine and its compounds in industrial and agricultural production is widely used, such as electrolytic aluminum, metallurgy, hydrofluoric acid, fluoride salt, phosphate fertilizer, glass and chemical industry and pesticide pesticides and other production processes, workers have more fluorine s contact. Long-term intake of more fluoride and its compounds will lead to skeletal fluorosis, the X-ray showed osteopetrosis, increased bone mineral density, ligament calcification and calcification tendon adhesion has been well-known. In advanced cases, diagnosis is not difficult due to its clinical manifestations and X-ray findings. Foreign reports fluoride workers in poor working conditions, more than two years can be onset, ten years have been developed to late. Under the conditions of our proletarian dictatorship, since all levels of the party,
