👉 Peroxidation is a chemical reaction in which one or more atoms of oxygen are added to an organic compound. This process can lead to the formation of certain compounds, including peroxides, which are highly reactive and can undergo various reactions with other substances. Peroxidation can occur naturally through oxidation reactions, but it can also be caused by exposure to pollutants such as sulfur dioxide or ozone, as well as industrial processes that generate peroxides during chemical reactions.
