What are all the factors affecting ozone layer other than CFC?

Answer 1

Halons, carbon tetra chloride, methyl chloroform, methyl bromide

The ozone depletion potential (ODP) of a gas is defined as the decrease in total ozone per unit mass emission of CFC-11 (CFCl3). A reference gas is CFC-11, which has a global warming potential and an ODP of 1.0.

ODP values for methyl chloroform (C2H3Cl3) and two halons (mainly CF2ClBr and CF3Br) are 6, 12, and 0.1, respectively. ODP is not dependent on the amount of time needed for ozone depletion to occur.

Substances that deplete the ozone layer have grown in importance as part of the regulatory strategy. The World Meteorological Organization (The Scientific Assessment of Ozone Depletion, 2002) website provides further details.

Other factors affecting the ozone layer include nitrogen oxides (NOx), halons, methyl bromide, carbon tetrachloride, and nitrous oxide (N2O). Additionally, natural factors such as volcanic eruptions and solar variability can also impact the ozone layer.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
