Volatile organic compounds (VOCs) are organic compounds that have a high vapor pressure at room temperature. [1] High vapor pressure correlates with a low boiling point , which relates to the number of the sample's molecules in the surrounding air, a trait known as volatility .
Volatility (chemistry) Bromine liquid readily transitions to vapor at room temperature, indicating high volatility. In chemistry, volatility is a material quality which describes how readily a substance vaporizes. At a given temperature and pressure, a substance with high volatility is more likely to exist as a vapour, while a substance with ...
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, [1] other plants [2] (of the same or other species), animals, [3] insects, [4] and fungi. [5] Plants communicate through a host of volatile ...
Environment portal. Ecology portal. v. t. e. Persistent organic pollutants (POPs) are organic compounds that are resistant to degradation through chemical, biological, and photolytic processes. [1] They are toxic and adversely affect human health and the environment around the world. [1]
Volatility (chemistry), a measuring tendency of a substance or liquid to vaporize easily. Volatile organic compounds, organic or carbon compounds that can evaporate at normal temperature and pressure. Volatile anaesthetics, a class of anaesthetics which evaporate or vaporize easily. Volatile substance abuse, the abuse of household inhalants ...
Volatolomics is a branch of chemistry that studies volatile organic compounds (VOCs) emitted by a biological system, under specific experimental conditions. Etymology. According to the Oxford English Dictionary, the suffix ‘omics’ refers to ‘the totality of some sort’.
Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH3)2CO. [22] It is the simplest and smallest ketone (>C=O). It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.
Volatile organic compounds (VOCs) may have higher concentrations in confined indoor environments, due to restricted infiltration of fresh air, as compared to the outdoor environment, leading to greater potential for toxic health exposures from a variety of chemical compounds. Health effects of odor are traced to the sensation of an odor or the ...
