氟是人体必需的微量元素,但过量摄入则会危害健康。六十年代末包头郊区及其毗邻地区羊群发生的“长牙病”,人间较多的斑釉症等就是由工业排放含氟废气(包钢)引起的人畜间的慢性氟中毒。从此,工业含氟废气对环境的污染已越来越引起人们的注意。我区青铜峡铝厂主要有害物质的排放源为电解、阳极糊和动力车间,能源以电力为主,主要生产原料为氧化铝、阳极糊、氟化盐等。据初步估算,每年向大气排放氟化物 (气态和尘态)690吨,还有CO、SO_2、NO_x、
Fluorine is an essential trace element of the body, but excessive intake will be hazardous to health. The “long-term disease” in the herds of the Baotou suburb and adjacent areas in the late 1960s and the more common plaque in China are the chronic fluorosis among humans and animals caused by the industrial discharge of fluorine-containing waste gas (Baotou Steel). Since then, the pollution of industrial fluorine-containing exhaust gas has drawn more and more attention. Qingtongxia Aluminum Plant in our region the main source of emissions of hazardous substances for the electrolysis, anode paste and power plant, the main energy-based electricity, the main raw material for the production of alumina, anode paste, fluoride salt. According to preliminary estimates, 690 tons of fluoride (gaseous and dusty) are released into the atmosphere each year, and CO, SO_2, NO_x,
