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.
Indoor materials such as gypsum boards or carpet act as VOC 'sinks', by trapping VOC vapors for extended periods of time, and releasing them by outgassing. The VOCs can also undergo transformation at the surface through interaction with ozone. [42] In both cases, these delayed emissions can result in chronic and low-level exposures to VOCs. [50]
The most well understood of these substances are carbon monoxide (CO); small particulate matter; nitrous oxide; sulfur oxides; a range of volatile organic compounds, including formaldehyde, benzene and 1,3-butadiene; and polycyclic aromatic compounds, such as benzo-a-pyrene, which are thought to have both short and long-term health consequences ...
Compared to those sealed chambers, indoor spaces “are larger, have persistent emissions of volatile organic compounds, and higher air exchange rates,” says Massa.
An air purifier can have a significant impact on the quality of the air in your home. ... and almost 100% of volatile organic compounds and odors. Cigar smoke was quickly replaced by fresh air ...
(To get specific, pan-frying emitted 92.9 micrograms per cubic meter of air and 260 parts per billion of volatile organic compounds, while the air-fryer method produced 0.6 micrograms per cubic ...
Dodder seedlings show direct growth toward tomato plants (Lycopersicon esculentum) and, specifically, tomato plant volatile organic compounds. This was tested by growing a dodder weed seedling in a contained environment, connected to two different chambers. One chamber contained tomato VOCs while the other had artificial tomato plants.
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 ...
