We face aggressive odours with high potency active oxygen – ozone O3. Ozone is a natural, gaseous molecule, consisting of three oxygen atoms, and frequently occurs in nature.
In the stratosphere it protects our planet from ultraviolet solar radiation as ozone layer. It forms in minor concentrations with thunderbolts. The fact, that ozone is frequently related to air pollution, bestowed a rather hostile image on this gas - wrongfully! If applied in the right way it is an effective and non-polluting alternative to chemical processes.
Ozone consists of three oxygen atoms. Under near-Earth normal conditions the gas is instable and thus highly reactive. The ozone molecule quickly reacts with a wide range of organic and inorganic compounds. During this process of oxidation the ozone generally gets completely consumed and decomposes to oxygen.
