氟元素是组成人体的微量元素之一.它参与人体中钙和磷的新陈代谢.缺氟可致龋齿病;过量的氟将造成慢性氟中毒,氟中毒患者轻则出现氟斑牙和非气候性的腰腿酸疼;重则关节强直、活动受限、驼背蜷缩乃至瘫痪。地方性氟病是一种地球化学病,根据地质、地理及气候因素,可以划分为原生型和次生型两大类。原生型主要分布在基岩裸露的山区,和湿润、畅流而不利于氟化物浓集的南方.次生型主要分布在闭流盆地.淤积平原和盐渍化地区,以及干旱、强烈蒸发而有利于氟化物浓集的北方。
Fluorine is one of the trace elements that make up the human body, which is involved in the metabolism of calcium and phosphorus in the human body. Fluoride deficiency can cause dental caries. Excessive fluoride will cause chronic fluorosis. Fluoride poisoning may cause dental fluorosis and non-weathering Waist and leg aches; heavy joint stiffness, limited mobility, hunchback curled up and even paralyzed. Endemic fluorosis is a geochemical disease that can be divided into primary and secondary categories according to geological, geographical and climatic factors. The primary types are mainly distributed in the exposed mountainous areas of the bedrock and wet and smooth flow, which is unfavorable to the south of fluoride concentration.The secondary types are mainly distributed in the closure basins, silting plains and salinization areas, as well as drought and strong evaporation Fluoride-enriched northern.
