燃煤型氟中毒是我国近几年才发现的,而且是我国特有的一种氟中毒类型,在国外尚无报道。该病多发生于地处高寒山区,有很多裸露的高氟煤矿,埋藏表浅,易于开采。群众习惯用落后的无烟囱无盖板的地炉,将煤炭直接立放室内烧堆煤敞火,终年不断,用来取暖做饭、烘烤粮食、蔬菜。从煤中释放的氟严重的污染了室内空气、食物及饮用水而导致发病。 1985年四川彭水县卫生部门调查,查出该县氟中毒11.7万人,患病率占实查人数的24.35％,流行55个乡452个自然村,分别占乡村总数的85.94％和70.32％。中地 Coal-fired fluorosis is only found in recent years in our country, but also a type of fluorosis unique to our country, no reports in foreign countries. The disease occurred in the alpine mountainous areas, there are many exposed high-fluorine coal mines, shallow surface, easy to mining. People used to lag behind the non-chimney furnace without cover, the coal directly into the indoor burning coal fire, open year-round, used for heating cooking, baking food, vegetables. The release of fluoride from coal severely pollutes indoor air, food and drinking water and causes disease. In 1985, a survey conducted by the health department of Pengshui County in Sichuan Province found 117,000 cases of fluorosis in the county, accounting for 24.35% of the actual number of people surveyed and 452 villages in 55 townships accounting for 85.94% and 70.32% of the total number of villages respectively.
