Technique . Indoor VOCs react with the indoor ozone9 even at concentrations below public health standards. Products. European Union Publications Office. In the United States, emissions of VOCs to the outdoors are regulated by EPA mostly to prevent the formation of ozone, a constituent of photochemical smog. VOCs are sometimes categorized by the ease they will be emitted. 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. Speak to an engineer today! This substance is not a Related Substance of any other substance. Method 5000 provides more ge neral information … Sample Reports. Exit. Target Compound List (TCL) – VOC’s Dichlorodifluoromethane Chloromethane Bromomethane Vinyl Chloride Chloroethane Trichlorofluoromethane 1,1,2-Trichloro-1,2,2-trifluoroethane Methylene Chloride Acetone Carbon Disulfide Methyl Acetate 1,1-Dichloroethene 1,1-Dichloroethane cis-1,2-Dichloroethene trans-1,2-Dichloroethene Volatile organic compounds (VOC) means any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates and ammonium carbonate, which participates in atmospheric photochemical reactions, except those designated by EPA as having negligible photochemical reactivity2. For historical reasons, a few types of compounds such as carbonates, simple oxides of carbon and cyanides, as well as the allotropes of carbon, are considered inorganic. This terminology clarified its meaning as being limited to reactive chemicals. Each jurisdiction or country may have different official definitions for VOCs depending on whether the VOCs are indoor VOCs or outdoor VOCs. E761346 has replaced E524670809 and E966598. Illinois EPA Assistance Organic chemical compounds1 are everywhere in both indoor and outdoor environments because they have become essential ingredients in many products and materials. 214.926.4950 Home Substances with higher vapor pressure will vaporize more readily at a given temperature than substances with lower vapor pressure. The division between "organic" and "inorganic" carbon compounds is useful, but may be considered somewhat arbitrary. For example, the World Health Organization (WHO) categorizes indoor organic pollutants as: The higher the volatility (lower the boiling point), the more likely the compound will be emitted from a product or surface into the air. It is important for consumers to understand that information on labels or other product literature with broad claims about environmental impact using terms such as “green” or “environmentally friendly” may or may not include some of the VOCs emitted from the product, and therefore may not otherwise consider their adverse health effects. 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. This table shows how each list refers to the substance. Many VOCs form ground-level ozone by “reacting” with sources of oxygen molecules such as nitrogen oxides (NOx), and carbon monoxide (CO) in the atmosphere in the presence of sunlight. These lists include the parameters as defined in the EPA AQS system as "CORE HAPS" or "VOC". It is a tendency of a substance to vaporize or the speed at which it vaporizes. 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. The range of measurement methods and analytical instruments is large and will determine the sensitivity of the measurements as well as their selectivity or biases. You can view the list of parameters included in either catagory by visiting the AQS Code Tables page for Parameter Classes and searching for CORE_HAPS or VOC. For example, the European Union uses the boiling point, rather than its volatility in its definition of VOCs. When discussing indoor environments, all organic chemical compounds that can volatize under normal indoor atmospheric conditions of temperature and pressure are VOCs. IUPAC's standard is a temperature of 0° C (273, 15 K, 32° F) and an absolute pressure of 100 kPa (14.504 psi), NIST's definition is a temperature of 20° C (293, 15 K, 68° F) and an absolute pressure of 101.325 kPa (14.696 psi).
