What harm does fluorine do to human body?

Fluorine is a highly toxic gas, which can irritate eyes, skin and respiratory mucosa. Because it reacts with water immediately to produce hydrogen fluoride, it shows the same toxicity as hydrogen fluoride in most cases.

When the fluorine concentration is 5 ~ 10 ppm, it will irritate the mucous membranes such as eyes, nose and throat, and it can also cause pulmonary edema after long-term use. Contact with skin can cause hair burns, coagulation necrosis at the contact site, carbonization of epithelial tissue, etc. Long-term exposure can lead to bone sclerosis and ligament calcification. Patients who inhale fluoride should immediately move to a pollution-free and safe place to rest and keep warm and comfortable. When eyes or skin are irritated, wash them with water quickly, and then seek medical attention.
