NASA Clean Air Study
__NOTOC__ The NASA Clean Air Study was a project led by the National Aeronautics and Space Administration (NASA) in association with the Associated Landscape Contractors of America (ALCA) in 1989, to research ways to clean the air in sealed environments such as space stations. Its results suggested that, in addition to absorbing carbon dioxide and releasing oxygen through photosynthesis, certain common indoor plants may also provide a natural way of removing volatile organic pollutants (benzene, formaldehyde, and trichloroethylene were tested). These results are not applicable to typical buildings, where outdoor-to-indoor air exchange already removes VOCs at a rate that could only be matched by the placement of 10–1000 plants/m2 of a building’s floor space. The results also failed to replicate in future studies, with a 2014 review stating that "While the plant’s ability to take up VOCs is well documented in laboratory studies, the effect of plants on indoor air in complex ...

Epipremnum Aureum
''Epipremnum aureum'' is a species in the arum family Araceae, native to Mo'orea in the Society Islands of French Polynesia. The species is a popular houseplant in temperate regions but has also become naturalised in tropical and sub-tropical forests worldwide, including northern South Africa, Australia, Southeast Asia, South Asia, the Pacific Islands and the West Indies, where it has caused severe ecological damage in some cases. The plant has a number of common names including golden pothos, Ceylon creeper, hunter's robe, ivy arum, house plant, money plant, silver vine, Solomon Islands ivy, marble queen, and taro vine. It is also called devil's vine or devil's ivy because it is almost impossible to kill and it stays green even when kept in the dark. It is sometimes mistakenly labeled as a ''Philodendron, Pothos or Scindapsus'' in plant stores. It is commonly known as a money plant in many parts of the Indian subcontinent.

It is native to tropical and Southern Africa, but has become naturalized in other parts of the world, including Western Australia and the Bangladesh., search for "Chlorophytum comosum" ''Chlorophytum comosum'' is easy to grow as a houseplant because of its resilience, but it can be sensitive to the fluoride in tap water, which commonly gives it "burnt tips". Variegated forms are the most popular. Description ''Chlorophytum comosum'' grows to about tall, although as a hanging plant it can descend many feet. It has fleshy, tuberous roots, each about long.

Nephrolepis Obliterata
''Nephrolepis obliterata'', the Kimberley Queen fern or Australian swordfern, is a species of fern in the family Nephrolepidaceae. This fern originated in Australia, but is relatively easy to cultivate indoors worldwide. The often misspelled "Kimberley Queen" name correctly has a second "e" in the first name as is trademarked by Westland Laboratories Ply. Ltd. The Kimberley Queen is not as well known as the Boston fern. Because it is not as sensitive to a lack of humidity, it is better suited for the typical indoor environment. Cultivation ''Nephrolepis obliterata'' prefer bright, but indirect sunlight. Temperatures between 16 °C and 24 °C are best. ''Nephrolepis obliterata'' is sensitive to both too little and too much water, so water the plant well but permit the soil to dry out between waterings. ''Nephrolepis obliterata'' has the added benefit of reducing indoor air pollution, particularly formaldehyde, xylene, and toluene Toluene (), also known as toluol ( ...

Ammonia
Ammonia is an inorganic compound of nitrogen and hydrogen with the formula . A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct pungent smell. Biologically, it is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to 45% of the world's food and fertilizers. Around 70% of ammonia is used to make fertilisers in various forms and composition, such as urea and Diammonium phosphate. Ammonia in pure form is also applied directly into the soil. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. It is mainly collected by downward displacement of both air and water. Although common in nature—both terrestrially and in the outer planets of the Solar System—and in wide use, ammonia is both caust ...

Toluene
Toluene (), also known as toluol (), is a substituted aromatic hydrocarbon. It is a colorless, water-insoluble liquid with the smell associated with paint thinners. It is a mono-substituted benzene derivative, consisting of a methyl group (CH3) attached to a phenyl group. As such, its systematic IUPAC name is methylbenzene. Toluene is predominantly used as an industrial feedstock and a solvent. As the solvent in some types of paint thinner, permanent markers, contact cement and certain types of glue, toluene is sometimes used as a recreational inhalant and has the potential of causing severe neurological harm. History The compound was first isolated in 1837 through a distillation of pine oil by the Polish chemist Filip Walter, who named it ''rétinnaphte''. In 1841, French chemist Henri Étienne Sainte-Claire Deville isolated a hydrocarbon from balsam of Tolu (an aromatic extract from the tropical Colombian tree ''Myroxylon balsamum''), which Deville recognized as similar to Wa ...

Xylene
In organic chemistry, xylene or xylol (; IUPAC name: dimethylbenzene) are any of three organic compounds with the formula . They are derived from the substitution of two hydrogen atoms with methyl groups in a benzene ring; which hydrogens are substituted determines which of three structural isomers results. It is a colorless, flammable, slightly greasy liquid of great industrial value. The mixture is referred to as both xylene and, more precisely, xylenes. Mixed xylenes refers to a mixture of the xylenes plus ethylbenzene. The four compounds have identical empirical formulas . Typically the four compounds are produced together by various catalytic reforming and pyrolysis methods. Occurrence and production Xylenes are an important petrochemical produced by catalytic reforming and also by carbonization, coal carbonisation in the manufacture of coke (fuel), coke fuel. They also occur in crude oil in concentrations of about 0.5–1%, depending on the source. Small quantities occur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
