VOCs mean volatile organic compounds and are found in a wide variety of products such as solvent-based paints, printing inks, many consumer products, organic solvents and petroleum products. M otor vehicles and vessels also emit VOCs that eventually cause air pollution and smog.

Volatile organic compounds are produced in a high diversity in soils, some of them reflecting physiological properties or the presence of certain species. As part of the FRAPPÉ field campaign, a suite of volatile organic compounds were measured to characterize the sources of ozone precursors that contribute to high ozone in the park. These measurements indicate emissions from the Front Range in Colorado tied to oil and gas operations, urban areas, and the stratosphere contribute to episodes of elevated ozone. 揮発性有機化合物（きはつせいゆうきかごうぶつ、英: Volatile Organic Compounds）は、常温常圧で大気中に容易に揮発する有機化学物質の総称のことである。略称は、VOCs、VOC。 具体例としてはトルエン、ベンゼン、フロン類、ジクロロメタンなどを指し、これらは溶剤、燃料として重要な物質であることから、幅広く使用されている。しかし、環境中へ放出される Plants create volatile organic compounds, which are responsible for the scent of freshly cut grass, roses, and pine.

Residential Indoor Air Quality Guidelines; Indoor air reference levels 1 dag sedan · Bacillus subtilis is commonly used as a biocontrol bacterium owing to its strong antifungal activity, broad-spectrum inhibition, and general safety. In this study, the inhibitory effects of volatile organic compounds (VOCs) produced by B. subtilis CF-3 on Colletotrichum gloeosporioides, a major destructive phytopathogen of litchi anthracnose, were analyzed using proteomics and transcriptomics What are Volatile Organic Compounds (VOCs)?

Volatile Organic Compounds (VOC) are chemicals that vaporize (become a gas) at room temperature, and are the leading cause of ground-level air pollution (also known as “smog”). VOCs react with nitrogen oxides – particularly on hot summer days – … 2017-12-28 Total volatile organic compounds (TVOC) is a group of VOCs used to represent the entire pool of pollutants. If you have an air quality monitor with volatile organic compound detection capabilities, you will see your readings in terms of TVOC. Unfortunately, TVOC isn’t uniformly defined.

Se hela listan på cdph.ca.gov 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. Maintaining good indoor air quality (IAQ) is critical for health and safety. However, this can be a challenge due to the presence of volatile organic compounds (VOCs). These organic chemicals are substances made up of carbon and other elements, and they encompass nearly all carbon compounds with the exception of carbon dioxide and carbon monoxide.

Volatile Organic Compounds (VOCs) are hydrocarbons that become volatile (gas form) at room temperature. VOCs are also part of different tropospheric and stratospheric reactions which contributes to photochemical smog -when reacting with nitrogen oxides to form ozone (O3) at tropospheric and ground levels- and greenhouse effect at stratospheric level.
