Ozone therapy is an alternative medical treatment that introduces ozone or ozonides to the body. The United States Food and Drug Administration (FDA) prohibits all medical uses of ozone "in any medical condition for which there is no proof of safety and effectiveness", stating "ozone is a toxic gas with no known useful medical application in ...

High ozone shock treatment or ozone blasting is a process for removing unwanted odour, and killing mold, vermin and microorganisms in commercial and residential buildings. . The treatment is less expensive than some alternative methods of sterilizing indoor spaces - cleaning or removal of building material, or in extreme cases the abandonment of sick buildin
A vehicle tire showing signs of ozone cracking. An antiozonant, also known as anti-ozonant, is an organic compound that prevents or retards damage caused by ozone. The most important antiozonants are those which prevent degradation of elastomers like rubber. A number of research projects study the application of another type of antiozonants to ...
These include chlorofluorocarbons and hydrofluorocarbons, both of which cause ozone depletion (although the latter much less so) and contribute to global warming. 'Freon' is the brand name for the refrigerants R-12 , R-13B1 , R-22 , R-410A , R-502, and R-503 manufactured by The Chemours Company, and so is not used to label all refrigerants of ...
In real-world applications of wastewater treatment, however, this term usually refers more specifically to a subset of such chemical processes that employ ozone (O 3), hydrogen peroxide (H 2 O 2) and UV light [2] or a combination of the few processes. [3]
For example, R-22 has one carbon atom, one hydrogen atom (2−1 = 1), two fluorine atoms, and one chlorine atom (4−2−1 = 1), so it is chlorodifluoromethane, while R-134 has two carbon atoms (2−1 = 1), two hydrogen atoms (3−1 = 2), four fluorine atoms, and no chlorine atoms (6−2−4 = 0), so it is one of the tetrafluoroethanes. This ...
Cracks can be formed in many different elastomers by ozone attack, and the characteristic form of attack of vulnerable rubbers is known as ozone cracking. The problem was formerly very common, especially in tires , but is now rarely seen in those products owing to preventive measures.
