While VOCs can also be a health concern outdoors, EPA regulates VOCs outdoors mainly because of their ability to create photochemical smog under certain conditions. The most used, although not universally adopted, definitions are those of the International Union of Pure and Applied Chemistry (IUPAC) and the National Institute of Standards and Technology (NIST). Some of the most common VVOCs are: Emissions of volatile organic compounds (VOC) and hazardous air pollutants (HAP) from oil and natural gas production were investigated using direct measurements of component-level emissions on well pads in the Denver-Julesburg (DJ) Basin and remote measurements of production pad-level emissions in the Barnett, DJ, and Pinedale basins. Volatile organic compounds (VOCs) are one of the biggest silent threats to human health. methodology for deso rbing volatile organics from trapping media (Methods 0010, 0030, and 0031). EPA 624.1 is used to determine the concentrations of Volatile Organic Compounds (VOCs) in wastewater. Unfortunately, the use of the term “VOC” rather than ROG has created a misunderstanding when applied to indoor air quality. VOCs that are non-reactive or of negligible reactivity to form ozone under these conditions are exempted from the definition of VOCs used by EPA in its regulation. The division between "organic" and "inorganic" carbon compounds is useful, but may be considered somewhat arbitrary. A VOC is any organic compound having an initial boiling point less than or equal to 250° C measured at a standard atmospheric pressure of 101.3 kPa.5, 6, 7. In addition, the measured quantity and composition of VOCs in the air can vary significantly depending on the measurement methods used, which has generated additional confusion. In addition, some states have their own definitions and lists of exempted compounds. This lack of standardization makes it difficult for the consumer to fully understand what the labels and certifications mean in most cases. Products. 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. 214.926.4950 Home Summary. Burning fossil fuels also results in the release of VOCs into the atmosphere. Misunderstanding and Confusion about VOCs. Illinois EPA Assistance For example, methylene chloride (paint stripper), and perchloroethylene (dry cleaning fluid), are exempted compounds for outdoor regulation, but they could pose serious health risks to exposed individuals if present indoors. Controlling Emissions of Volatile Organic Compounds INTRODUCTION Controlling emissions of volatile organic com-pounds (VOC) is the primary strategy used by the Environmental Protection Agency (EPA) and most States for reducing urban ozone. The range of compounds analyzed by the method depends on the selection of the sorbent cartridge. For example, the European Union uses the boiling point, rather than its volatility in its definition of VOCs. EURO Reports and Studies 111. Volatile Organic Compounds list. Since first establishing the list of exempt compounds in 1977, the EPA has added several to the list, and frequently has several petitions for additional compounds undergoing review. For indoor air quality, ALL organic chemical compounds whose compositions give them the potential to evaporate under normal atmospheric conditions are considered VOCs and should be considered in any assessment of indoor air quality impacts. Volatile Organic Compound (VOC) Control Regulations VOCs react with nitrogen oxides on hot summer days to form ozone (smog). When discussing indoor environments, all organic chemical compounds that can volatize under normal indoor atmospheric conditions of temperature and pressure are VOCs. EPA TO-17 Volatile Organic Compounds Method TO-17 is used to analyze samples for volatile organic compounds collected on multi-bed sorbent tubes, which are thermally desorbed and cryo-focused on the capillary column and then analyzed by GC/MS. Car exhaust, gasoline-powered lawn and garden equipment, gasoline dispensing stations, industrial coating operations, printing shops, paints, household chemicals - are some of the sources of VOC. This is why any statement about VOCs that are present in a given environment needs to be accompanied by a description of how the VOCs were measured so that the results can be interpreted correctly by a professional. EPA GC-MS methods for VOC analysis. Other than volatility (or boiling point) no other criteria are used to define VOCs indoors. This has created a misunderstanding in the marketplace and in the environmental community. United States Environmental Protection Agency. VOCs are sometimes categorized by the ease they will be emitted. Very volatile organic compounds are so volatile that they are difficult to measure and are found almost entirely as gases in the air rather than in materials or on surfaces. The EPA also publishes testing methods for chemical compounds, some of which refer to VOCs. Toxic substances list: volatile organic compounds Volatile organic compounds (VOCs) are organic compounds containing one or more carbon atoms that evaporate readily into the atmosphere. The U.S. Environmental Protection Agency (EPA) estimates that VOCs are present in one-fifth of the nation’s water supplies. Report final analyte concentration in units of micrograms per liter (µg/L). Learn more about SRS. When inhaled they can be extremely dangerous to … Report results that are less than 10 µg/L to 1 significant figure, and results that are greater than or equal to 10 µg/L to 2 significant figures. They do not include photo-chemically non-reactive compounds such as methane, ethane and the chlorofluorocarbons (CFCs). Environmental Protection Agency Data Systems.
