Volatile organic compounds (VOCs) are organic compounds that have a high vapor pressure at room temperature. [1] They are common and exist in a variety of settings and products, not limited to house mold , upholstered furniture , arts and crafts supplies, dry cleaned clothing, and cleaning supplies . [ 2 ]
For example, air concentrations of volatile organic compounds declined by a factor of 50 between 1962 and 2012. [109] Concentrations of air pollutants such as nitrous oxides and ozone declined by 70% to 80% over the same period of time.
In the US, dimethyl carbonate was exempted under the definition of volatile organic compounds (VOCs) by the U.S. EPA in 2009. [9] Due to its classification as VOC exempt, dimethyl carbonate has grown in popularity and applications as a replacement for methyl ethyl ketone (MEK) and other solvents.
Volatile organic compounds (VOCs) are organic chemicals, some of which occur naturally in oil and gas, that have high vapor pressure at ordinary room temperature. As a result, these chemicals exhibit an ease of transition from the liquid to the vapor state under atmospheric (ambient) conditions.
Vapor intrusion (VI) is the process by which chemicals, usually volatile organic compounds (VOCs), in soil or groundwater migrate to indoor air above or around a contaminated site. [1] The process of VI has been studied more recently in relation to its effects on humans and the environment, and is becoming more regulated by the United States ...
Toluene is an organic compound which is mostly harmless to adults and is sometimes abused as an inhalant. Fetal toluene syndrome has been defined and resembles fetal alcohol syndrome with resultant birth defects, but the U.S. Centers for Disease Control and Prevention have identified differentiating features between the two syndromes including FTS having the additional facial features of ...
Thermal oxidizers are typically used to destroy hazardous air pollutants (HAPs) and volatile organic compounds (VOCs) from industrial air streams. These pollutants are generally hydrocarbon based and when destroyed, via thermal combustion, they are chemically oxidized to form CO 2 and H 2 O. Three main factors in designing the effective thermal ...
The volatilome (sometimes termed volatolome [1] or volatome [2] [3] [4]) contains all of the volatile metabolites as well as other volatile organic and inorganic compounds that originate from an organism, [5] [6] [7] super-organism, or ecosystem. The atmosphere of a living planet could be regarded as its volatilome.
