Very Volatile Organic Compounds (VVOC) VVOCs have a boiling point range of <0 to 50100 degrees centigrade. Due to their high volatility, these compounds often exist solely as a gas. Manufacturers using chemicals and solvents that produce VVOCs must be equipped to capture and dispose of these emissions with great efficiency.

The term TVOC refers to the total concentration of multiple airborne VOCs present simultaneously in the air. TVOC methods do not measure all VOCs in the air, but a subset of VOCs that are expected to be present. Measuring TVOC concentrations is less expensive than measuring the concentrations of many individual VOCs.
Sep 13, 2017· According to Korean Women’s Environmental Network (KWEN), all the products contained TVOC components above the legal standard allowed in public spaces — one product over 500 times. TVOC indicates the total amount of volatile organic compounds in indoor air, which causes irritation and can also damage liver, kidney and central nervous system.
Volatile organic compounds, or VOCs are organic chemical compounds whose composition makes it possible for them to evaporate under normal indoor atmospheric conditions of temperature and pressure 3. This is the general definition of VOCs that is used in the scientific literature, and is consistent with the definition used for indoor air quality.
