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...

Volatile organic compounds (VOCs) are organic chemical compounds that have high enough vapour pressures under normal conditions to significantly vaporize and enter the atmosphere. A wide range of carbon-based molecules, such as aldehydes, ketones, and...

Tri-TAC, a technical advisory committee based in California which focuses on publicly-owned treatment works, had developed a control guidance document for reducing volatile organic compound emissions. Designers, operators and regulators alike are expected to benefit from the document. Among the information provided by the...

Strict environmental regulations prompted the printing industry to employ control systems that will reduce emissions of volatile organic compounds (VOCs). These also led to the technological advancement of VOC-control units which remove and destroy VOCs and other hazardous compounds. The most preferred units are...

Sinclair Oil Corp., has agreed to pay $2.45 million in civil penalties and reduce emissions from three of its refineries in Wyoming and Oklahoma as part of a clean air settlement with the government, the Justice Department announced Tuesday.Under the agreement, filed in U.S. District...

The Environmental Protection Agency, following a congressional mandate, finalized plans Tuesday for new standards to boost the use of renewable fuels such as ethanol and biodiesel.Refiners will be required to use at least 7.5 billion gallons of renewable fuel in gasoline by 2012, the EPA...

VOCs, also known as Volatile Organic Compounds contain carbon atoms. VOCs evaporate quickly from water into air at room temperatures. They are used in the production of a wide variety of industrial, commercial and products such as gasoline, paints, and pesticides. VOCs can not be identified through smell or taste. Examples of VOCs include methane, benzene, toluene, methylene chloride, and methyl chloroform.
