  2. Volatile organic compound - Wikipedia

    en.wikipedia.org/wiki/Volatile_organic_compound

    The VOC Solvents Emissions Directive was the main policy instrument for the reduction of industrial emissions of volatile organic compounds (VOCs) in the European Union. It covers a wide range of solvent-using activities, e.g. printing, surface cleaning, vehicle coating, dry cleaning and manufacture of footwear and pharmaceutical products.

  3. VOC exempt solvent - Wikipedia

    en.wikipedia.org/wiki/VOC_exempt_solvent

    Due to its classification as VOC exempt, dimethyl carbonate has grown in popularity and applications as a replacement for methyl ethyl ketone (MEK) and other solvents. tert-Butyl acetate is used as a solvent in the production of lacquers, enamels, inks, adhesives, thinners and industrial cleaners. [10] [11] It also gained EPA VOC exempt status.

    It is still employed with a focus on volatile organic compounds (VOCs) found in body odor. [2] VOCs are carbon-based molecular groups having a low molecular weight, secreted during cells' metabolic processes. [3] Their profiles may be altered by diseases such as cancer, metabolic disorders, genetic disorders, infections, and among others.

    NOx, CO, and VOCs are considered ozone precursors. [ 9 ] [ 6 ] Motor vehicle exhaust, industrial emissions, and chemical solvents are the major anthropogenic sources of these ozone precursors. [ 6 ] Although the ozone precursors often originate in urban areas, winds can carry NOx hundreds of kilometers, causing ozone formation to occur in less ...

  9. Indoor air quality - Wikipedia

    en.wikipedia.org/wiki/Indoor_air_quality

    Some VOCs are emitted directly indoors, and some are formed through the subsequent chemical reactions that can occur in the gas-phase, or on surfaces. [41] [42] VOCs presenting health hazards include benzene, formaldehyde, tetrachloroethylene and trichloroethylene. [43] VOCs are emitted by thousands of indoor products.
