Human poison by ingestion. Experimental poison by ingestion, skin contact, intravenous, intraperitoneal, subcutaneous, and intramuscular routes. Human systemic effects: changes in teeth and supporting structures, cyanosis, diarrhea, EKG changes, fluid intake, headache, hypermotility, increased immune response, muscle weakness, musculo-skeletal changes, nausea or vomiting, paresthesia, ptosis (drooping of the eyelid from sympathetic innervation), respiratory depression, salivary gland changes, tremors. Experimental teratogenic and reproductive effects. Human mutation data reported. A corrosive irritant to skin, eyes, and mucous membranes. Questionable carcinogen with experimental tumorigenic data. It is very phytotoxic. When heated to decomposition it emits toxic fumes of F? and Na2O. Used in chemical cleaning, for fluoridation of drinking water, as a fungicide and insecticide.
