Sources of the pollutant

Perfluorocarbons (PFCs) are compounds of carbon and fluorine atoms. They are produced exclusively by chemical synthesis and widely used in the manufacture of semi-conductors. They are also a by-product of aluminium electrolysis and trifluoroacetic acid production. Process improvements and optimisation have considerably reduced emissions of PFCs since 1990.

 

Effect of the pollutant

PFCs contribute to the greenhouse effect. Their global warming potential (GWP) varies depending on the years and molecules considered (see table below for the GWP per molecule - GWP values from the Intergovernmental Panel on Climate Change (IPCC)'s fourth assessment report published in 2007).

Compound PFC-14 PFC-116 C3F8 C4F8 C4F10 C5F12 C6F14 C10F18
GWP 7 390 12 200 8 830 10 300 8 860 9 160 9 300 7 500

PFCs have impacts on human health and they are demonstrated or suspected to be endocrine disruptors and carcinogenic.
