Evaluation of the correlation between concentration of volatile organic compounds and temperature of the exhaust gases in motor vehicles

E3S Web of Conferences, 2017
Volatile organic compounds (VOCs) are the group of organic compounds which are one of the most important air pollutants. One of the main sources of VOCs are combustion processes including fuel combustion is internal combustion engines.

Pathophysiology of SARS-CoV-2 Infection in the Upper Respiratory Tract and Its Relation to Breath Volatile Organic Compounds

mSystems, 2021
Among the many products of metabolic processes are volatile organic compounds (VOCs). In the airways, these volatile metabolites are emitted through breathing and thus are easily sampled for analysis.

Are Some Fungal Volatile Organic Compounds (VOCs) Mycotoxins?

Toxins, 2015
Volatile organic compounds (VOCs) are carbon-compounds that easily evaporate at room temperature. Toxins are biologically produced poisons; mycotoxins are those toxins produced by microscopic fungi.

Estimating European volatile organic compound emissions using satellite observations of formaldehyde from the Ozone Monitoring Instrument [PDF]

, 2010
Emission of non-methane Volatile Organic Compounds (VOCs) to the atmosphere stems from biogenic and human activities, and their estimation is difficult because of the many and not fully understood processes involved.
