The chart below shows the national summary of volatile organic compounds (VOCs) emissions by source sector based on the most recent inventory. These regulations set concentration limits of volatile organic compounds for fifty-three categories of architectural coatings identified in the schedule of the regulations. Their high vapor pressure results from a low boiling point, which causes large numbers of molecules to evaporate or sublimate from the liquid or solid form of the compound and enter the surrounding air. Residential Indoor Air Quality Guidelines; Report a problem or mistake on this page . As of 3/31/2009 . Note: EPA no longer updates this information, but it may be useful as a reference or resource. This amendment added these 16 compounds to the exclusion list of the VOC definition. 374 of 1997. 51.100 (s). 39 5.4.5 EPA Method 29 . High vapor pressure correlates with a low boiling points, which relates to numbers of the sample's molecules in the surrounding air, a trait known as volatility.

The term "volatile organic compounds' (VOCs) was originally coined to refer, as a class, to carbon-containing chemicals that participate in photochemical reactions in the ambient (outdoor) are. The term "semi-volatile compounds" refers to organic compounds that possess Henry’s law constants (H) ... Due to these health risks, regulatory agencies, such as the Environmental Protection Agency (EPA), have defined maximum allowable levels of PAHs in the environment. There is a limited threshold for volatile organic compound tolerance before your health is at risk. An EPA volatile organic compound is an organic compound that is determined, by the EPA, to have an especially high photochemical reactivity, or vaporization effect, under normal atmospheric conditions. VOCs are of interest in part because they participate in atmospheric photochemical reactions that contribute to ozone formation. It has a spelling mistake. VOLATILE ORGANIC COMPOUNDS BY GAS CHROMATOGRAPHY/ MASS SPECTROMETRY (GC/MS) 1.0 SCOPE AND APPLICATION 1.1 Method 8260 is used to determine volatile organic compounds in a variety of solid waste matrices. Condensibks (Polycyclic Organic Matter . This process, known as offgassing, releases harmful chemicals into the air. EPA has defined “VOC” very broadly. Some common examples include: toluene; xylenes; benzene; ethylbenzene; formaldehyde; More information. The term often is used in a legal or regulatory context and in such cases the precise definition is a matter of law. EPA 624.1 is used to determine the concentrations of Volatile Organic Compounds (VOCs) in wastewater. Impact/Purpose: Information.
