Volatile organic compounds (VOCs) are a wide range of carbon based (organic) chemicals (compounds) found in various man-made and naturally occurring solids and liquids. They evaporate easily at ordinary room temperature which is why they are termed volatile.

Volatile organic compounds (VOCs) are organic chemicals that readily produce vapors at ambient temperatures, and are therefore emitted as gases from certain solids or liquids. All organic compounds contain carbon, and organic chemicals are the basic chemicals found in all living things.
