volatile organic compound

Our bodies, and all living things, are made up of them; most common sugars, fats, proteins, and alcohols are organic compounds. Volatile organic compounds, or VOCs, are essentially just carbon-based chemicals that can quickly evaporate into a gas or vapor. Household use of solvent contaminated water may result in solvent intake from inhalation and dermal and oral absorption. In addition, they can react with other gases and form other air pollutants after they are in the air. In either case, the invasion of the pathogen results in production and release of various volatile organic compounds (VOCs). Glossary of Volatile Organic Compounds • Ethylbenzene • Carbon tetrachloride • Benzene • 1,1,1-Trichloroethane • Xylenes • Tetrachloroethylene • Toluene • Trichloroethylene • Styrene • 1,4-Dichlorobenzene They are called organic compounds because they contain the element carbon.
