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. Sources of VOCs include gasoline, industrial chemicals such as benzene, solvents such as toluene and xylene, and perchlorethylene (principal dry cleaning solvent). The provisions of this Rule shall not apply to: a. (m) “Volatile Organic Compound (VOC)” means any compound containing at least one atom of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, and excluding the following: (1) methane, methylene chloride (dichloromethane), 1,1,1-trichloroethane (methyl chloroform), This systematic review investigated whether domestic VOC exposure increases the risk of developing and/or exacerbating asthma and allergic disorders. Namiesnik et al.5 estimated volatile aliphatic amine concentrations in a pharmaceutical plant, a chemical stockroom, a car paint shop, and a city market, finding triethylamine concentrations up to 148.2 mg m−3 in the pharmaceutical plant. Microbial volatile organic compounds (MVOCs) are volatile organic compounds that can be produced by microorganisms in their primary or secondary metabolism. Organic chemicals are widely used as ingredients in household products. Additional sources of release are paints, glues, and other products that are used and stored at home and at work.

VOCs from paint dissipate fairly quickly with most offgassing occuring during the first 6 months after application. The two resonating structure in compound A, are not equivalent, whereas compound B, having a negative charge on the oxygen atom is having the two equivalent structures, hence the compound B is more stable. All organic compounds have carbon as the central element, attached to different functional groups. 10 Most Common VOCs. Pennerman, ... J.W. A volatile organic compound (VOC) is defined by the US Environmental Protection Agency (EPA) as ‘any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, which participates in atmospheric photochemical reactions’ (www. gwaps96 gwaps96 16.10.2019 Science Junior High School Which of the following organic compounds is NOT volatile? 1. From: Essential Oil Safety (Second Edition), 2014, S.S. Anand, ... H.M. Mehendale, in Encyclopedia of Toxicology (Third Edition), 2014. They include both human-made and naturally occurring chemical compounds. Microorganisms are known to produce a range of VOCs, so-called microbial VOC (MVOC). In an environmental analysis context, the VOC designation, or volatile organic contaminants, generally refers to the analysis of compounds in environmental samples with the following chemical properties:+. Question options: ozone (O 3) sulfur dioxide (SO 2) radon (Rn) carbon monoxide (CO) Carbon monoxide (CO) has a strong pungent odor that warns of its presence before concentrations can build to dangerous levels. F.A. VOCs are frequently used to dissolve, dilute, or disperse materials that are insoluble in water. Initially, to be called an organic compound it had to come from a living organism. They have been used to discover cryptic molds in the indoor environments; to detect contamination of stored food crops; and are under investigation as a possible medical diagnostic tool for aspergillosis. Volatile organic compounds (VOCs), produced and emitted through the metabolism of cancer cells or the body’s immune system, are considered novel cancer biomarkers for diagnostic purposes. A. oil C. acetone B. kerosene D. all of the above 2 The State of Minnesota’s Department of Health classifies volatile organic compounds as the following; “Volatile organic compounds (VOCs) are a large group of chemicals that are present in many products that are used to construct and maintain a home. In this way, groundwater contamination associated with an industrial facility was potentially responsible for indoor contamination by trichloroethylene and 1,2-dichloroethane in residences outside the facility boundary.
