ozonavnøytrale
Ozonavnøytrale refers to substances that do not deplete the ozone layer. The ozone layer, located in the Earth's stratosphere, is crucial for absorbing most of the sun's harmful ultraviolet (UV) radiation. For decades, certain chemicals, primarily chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), were widely used in refrigerants, aerosols, and solvents. These compounds, when released into the atmosphere, rise to the stratosphere and break down, releasing chlorine atoms that catalytically destroy ozone molecules.
The recognition of the damaging effect of these ozone-depleting substances led to international agreements, most notably
