What are Chlorofluorocarbons (CFCs)?<\/h2>\n\n\n\n

Chlorofluorocarbons (CFCs) are generally a mixture of chemicals that are commonly used as a refrigerant. They are used as propellants in aerosol sprays too. CFCs generally contain different substances, including fluorine, carbon, chlorine, and hydrogen.<\/p>\n\n\n\n

Chlorofluorocarbons (CFCs) are generally colourless and odourless, which is why they are a bit more difficult to detect. CFCs are generally quite volatile, and start evaporating immediately when they\u2019re exposed to open air.<\/p>\n\n\n\n

That is one of the main reasons why they can be inhaled<\/a> so easily. Even though CFCs are considered non-toxic<\/a>, exposure<\/a> (commonly through inhalation) can result in respiratory issues and may even cause a person to lose consciousness. <\/p>\n\n\n\n

In some cases, CFCs can result in arrhythmia. Some people also experience skin or eye irritation as a result. <\/p>\n\n\n\n

The Importance of Finding Substitutes for Chlorofluorocarbons (CFCs)<\/h2>\n\n\n\n

Because of its wide-ranging applications, CFCs are commonly used in a variety of industries. From their use in refrigeration to aerosol sprays and in packing materials, CFCs play an important role in various applications. <\/p>\n\n\n\n

CFCs are generally inert in the lower atmosphere, so their release isn\u2019t immediately harmful. However, as CFCs reach the upper atmosphere, the change in the atmospheric composition results in a significant reaction. <\/p>\n\n\n\n

For starters, a study in 1974 showed that CFCs are one of the prime sources for the release of inorganic chlorine within the stratosphere. That released chlorine then causes a depletion of the ozone layer, an important gas that prevents ultraviolet radiation from reaching the ground. <\/p>\n\n\n\n

As a result, in 1987, around 27 nations signed a treaty, known as the Montreal Protocol<\/a> to Reduce Substances that Deplete the Ozone Layer.\u00a0 An excessive release of CFCs is one of the major causes of ozone depletion.\u00a0<\/p>\n\n\n\n

Ozone depletion then creates a knock-on effect, resulting in:<\/p>\n\n\n\n
