Volatile organic compounds (VOCs) are small organic molecules that take part in photochemical reactions in the atmosphere, resulting in smog. They have low boiling points and vaporize easily. When present in the atmosphere, VOCs, such as benzene and...

In environmental science, the term usually refers to the hydrocarbons, especially those found in air pollution. In 1988, the five most abundant of these hydrocarbons in urban air were isopentane, n-butane, toluene, propane, and ethane; each of these...
