Examples of volatile anthropogenic chemicals include the refrigerants chlorofluorocarbons (CFCs) and hydrofluorocarbons (HCFCs). Stratospheric ozone depletion is caused by air pollution, chiefly from chlorofluorocarbons and other ozone-depleting substances. Traditionally chlorofluorocarbons (CFCs) were the predominant fluorinated organic chemical. Chlorofluorocarbons, which are banned or highly regulated, were widely used in cleaning products and refrigerants. Although structurally similar to chlorofluorocarbons (CFCs), tetrafluoromethane does not deplete the ozone layer. These include the chlorofluorocarbons (CFCs) that cause ozone depletion and HCFCs (such as chlorodifluoromethane). In 2009, the FDA banned the use of inhalers that use chlorofluorocarbons (CFC) as propellants. It was commonly used before the popularisation of chlorofluorocarbons (Freons). In 1973 James Lovelock speculated that chlorofluorocarbons (CFCs) could have a global warming effect. These radicals are formed by the action of ultraviolet radiation on chlorofluorocarbons (CFCs). Carbon dioxide, pentane, and chlorofluorocarbons are examples of the former. South Korea is the second-largest consumer of ozone-depleting chlorofluorocarbons. The original impetus was to eliminate chlorofluorocarbons (CFC), which was a former component of foam. Does the harm from chlorofluorocarbons increase every year and in the same increment? Description&colon; This paper warned of the danger of ozone depletion due to man-made chlorofluorocarbons.
