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 ]
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.
All volatile metabolites detectable by the human nose are termed an 'odour profile'. The association of altered odour profiles with disease states has long been documented in both eastern and western medicine, and recent advances in robotic sample introduction have increased interest in the volatilome as a source for biomarkers that can be used for non-invasive screening for disease.
Plant communication encompasses communication using volatile organic compounds, electrical signaling, and common mycorrhizal networks between plants and a host of other organisms such as soil microbes, [2] other plants [3] (of the same or other species), animals, [4] insects, [5] and fungi. [6]
Volatile organic compounds (VOCs) are released from many household cleaning products such as disinfectants, polishes, floor waxes, air-freshening sprays, all-purpose cleaning sprays, and glass cleaner. These products have been shown to emit irritating vapors.
Volatile organic compounds (VOC): VOCs are both indoor and outdoor air pollutants. [87] They are categorized as either methane (CH 4 ) or non-methane (NMVOCs). Methane is an extremely efficient greenhouse gas which contributes to enhanced global warming .
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 ...
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 ...
