Fluoride compounds: Sources of emissions

Industry sources

The primary sources of fluoride emissions are the industries that manufacture it or use it in production. Some of the industries that use it in production are aluminium industry, oil drilling and refining, the chemical and plastics industries, agricultural and pesticide chemical manufacturers, dye manufacturers, manufacturers of metal parts. These are emissions to the air unless there is a spill.

Diffuse sources, and industry sources included in diffuse emissions data

Other possible emitters of fluoride are metal cleaning operations, glass and enamel manufacturing and glazing, toothpaste, and fluoride enhanced water. These emissions may be to the soil, water, or air.

Natural sources

Fluorine is a naturally occurring element in the earth, but elemental fluorine is too reactive to be found in nature. Fluorine is found in nature as part of the mineral fluorspar. Water in rivers or streams that flow over rocks rich in fluorine-containing minerals such as fluorspar may naturally contain dissolved fluoride.

Transport sources

No known mobile sources.

Consumer products

Toothpaste, pesticides, ceramic and glass polishing etching and frosting materials, special dyes, drinking water in some areas may be naturally or artificially enriched in fluoride.
