Total Volatile Organic Compounds (TVOC) in Indoor Air Quality ...

TVOC values reported in the literature are mostly not comparable. To increase comparability, TVOC must be defined clearly. Such a definition is given for a specified range of VOCs. The measured concentrations expressed as mass per air volume of identified VOCs within that range are added. Non-identified compounds in toluene equivalents are included and, together with the identified VOCs, they give the …

Total Volatile Organic Compounds | National Pollutant Inventory

TVOC is a grouping of a wide range of organic chemical compounds to simplify reporting when these are present in ambient air or emissions. Many substances, such as natural gas, could be classified as volatile organic compounds (VOCs). VOCs are reserved for characterisation of such substances in polluted air, that is, VOCs generally refer to vapours of gases given off by compounds rather than the liquid phase. …

Volatile organic compound - Wikipedia

Volatile organic compounds (VOC) are organic chemicals that have a high vapour pressure at room 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.. VOC's are responsible for the odor of scents and perfumes as well as pollutants.
