Volatile Organic Compounds (VOC)
Every day, large quantities of volatile organic compounds (VOCs) are emitted to the atmosphere from both anthropogenic and natural sources. These substances influence local, regional and even global photochemistry and several of them, in addition, have a potential impact on the climate, due to their properties of greenhouse gases and as well ability to form aerosol particles on oxidation. Tens of thousands of natural compounds have been detected in the air we breathe, mixing at various ratios. Volatile Organic Compounds are organic substances primary made up of carbon and hydrogen. However, may also contain atoms such as sulphur, oxygen, nitrogen, or chlorine. VOCs are volatile in that they evaporate under the climate generally found at Earth’s surface The Environmental Protection Agency (EPA) in the United States has defined VOC as any compound that participates in atmospherically photochemical reactions; nevertheless, there have been there had been posterior attempts to give a more precise definition. As a result, VOC is, therefore, altogether to be those organic compounds having a vapour pressure greater than 10 pa at 25◦C, a boiling point of up to 260◦C at the atmospherical pressure, and 15 or fewer carbon atoms.
