    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.

    In 1982, the Marine Corps discovered volatile organic compounds (VOCs) in several drinking water wells that fed into two of the eight water systems. The sources were traced to tetrachloroethylene (PCE) from a two dry cleaners – one on base, the other off the base and trichloroethylene which had been used in vehicle maintenance on the base ...

    en.wikipedia.org/wiki/Ground-level_ozone

    Ground-level ozone is both naturally occurring and anthropogenically formed. It is the primary constituent of urban smog, forming naturally as a secondary pollutant through photochemical reactions involving nitrogen oxides and volatile organic compounds in the presence of bright sunshine with high temperatures.

    en.wikipedia.org/wiki/Vapor_intrusion

    Vapor intrusion (VI) is the process by which chemicals, usually volatile organic compounds (VOCs), in soil or groundwater migrate to indoor air above or around a contaminated site. [1] The process of VI has been studied more recently in relation to its effects on humans and the environment, and is becoming more regulated by the United States ...

    Most filters on the market are designed to capture particles like dust, smoke and pollen, but they don’t catch gases like VOCs (volatile organic compounds) or radon that may accumulate from ...

  8. Environmental impact of paint - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of_paint

    Low-VOC paint types include latex (water-based), recycled latex (water-based), acrylic, and milk paint. [1] [2] The labels of paint cans can be checked for the following information: To be considered low-VOC, the paint should contain <50 g/L of VOC. [citation needed] To be considered zero-VOC, the paint should contain <5 g/L of VOC. [citation ...

  9. NOx - Wikipedia

    en.wikipedia.org/wiki/NOx

    NO x reacts with volatile organic compounds in the presence of sunlight to form ozone. Ozone can cause adverse effects such as damage to lung tissue and reduction in lung function mostly in susceptible populations (children, elderly, asthmatics). Ozone can be transported by wind currents and cause health impacts far from the original sources.
