When the phaseout of ozone-destroying chlorofluorocarbons (CFCs) was first agreed in 1987, the world narrowly avoided an environmental catastrophe. However, the replacement of CFCs is causing the pollution of the Earth’s surface with a “forever chemical” that could remain in the environment for centuries.
The chemical trifluoroacetic acid (TFA) is a breakdown product of numerous chemicals, including CFC replacement gases used in refrigeration and air conditioning, pharmaceuticals such as gases used in inhalation anaesthesia, pesticides, solvents and other forever chemicals from a class known as per-and polyfluoroalkyl substances (PFAS).
