Low VOC Materials - VOC’s, or Volatile Organic Compounds, are chemicals which evaporate into the air during the curing or, in some cases, throughout the life of the material.
VOC Paints and Products: Volatile Organic Compounds (VOC) are found in many paints and other products. VOCs are emitted as gases from certain room temperature solids and liquids.
2-Hexanone - C6H12O is a volatile organic compound (VOC) which are a large family of carbon-containing compounds which are emitted into the atmosphere from a variety of industrial processes.
When gasoline and coal are burned, nitrogen oxide gases (NOx) and volatile organic compounds (VOC) are released into the air.
VOC See volatile organic compound. volatile organic compound One of several organic chemical compounds characterized by its ability to evaporate readily at normal temperatures.
A control device that oxidizes volatile organic compounds (VOCs) by using a catalyst to promote the combustion process. Catalytic incinerators require lower temperatures than conventional thermal incinerators, thus saving fuel and other costs.
Catalytic Incinerator: A control device that oxidizes volatile organic compounds (VOCs) by using a catalyst to promote the combustion process.

Air Stripping: A treatment system that removes volatile organic compounds (VOCs) from contaminated ground water or surface water by forcing an airstream through the water and causing the compounds to evaporate.
In-Situ Stripping: Treatment system that removes or "strips" volatile organic compounds from contaminated ground or surface water by forcing an airstream through the water and causing the compounds to evaporate.
precursor 1) In photochemistry, a compound antecedent to a volatile organic compound (VOC). Precursors react in sunlight to form ozone or other photochemical oxidants. 2) In water or wastewater treatment, a compound that may be hologenated.
