Fluorine is the most active non-metallic element and reacts readily with a variety of elements and chemicals. Meanwhile, fluorine is one of the essential trace elements for human body, and is taken into the body mainly through drinking water, breathing and food. Excessive uptake of fluorine can have an adverse effect on human health. When the fluorine content of the drinking water is more than 1.0mg/L, dental fluorosis and fluorosis can be caused after long-term drinking. When the fluorine content exceeds 6.0mg/L, severe osteofluorosis with disability can be caused, which is manifested by skeletal deformation, general pain, loss of labor capacity and even paralysis.
