氟是维持机体正常生命活动所必需的微量元素,氟的摄入是通过饮食、呼吸、饮水三个主要途径进入人体的,此外,也可通过含氟药物、烟尘、酒和茶等进入体内。一般来说,对饮水中的氟吸收率最高可达90%,其次是食物中的氟吸收率约20%。氟的过量摄入可导致氟中毒,国内外大量调查资料证实,饮水含氟量高是地方性氟中毒的主要原因。因此,如何采用有效的方法解决氟污染问题,是我们面临的一项重要任务。
Fluorine is a trace element necessary to maintain the normal life activities of the body. Fluorine intake enters the body through the three main ways of diet, breathing and drinking water. In addition, fluorine can also enter the body through fluorine-containing drugs, soot, wine and tea. In general, up to 90% of fluoride is absorbed in drinking water, followed by about 20% of fluorine in food. Excessive intake of fluoride can lead to fluorosis, a large number of domestic and foreign investigations confirmed that the high fluoride content in drinking water is the main reason for endemic fluorosis. Therefore, how to solve the problem of fluorine pollution in an effective way is an important task we are facing.
