Uranium-thorium dating
Chemistry; Atmospheric chemistry
An absolute dating technique which uses the properties of the radioactive half-life of Uranium-238 and Thorium-230. The half-life of uranium-238 is 4. 5 billion years, that is, in that many years ...
Air quality index (AQI)
Chemistry; Atmospheric chemistry
An accounting or measurement of specified toxic levels of pollutants in the air. Based on the EPA air quality act, it gives the indicator (number) of different gas phase concentration levels to ...
Quicklime
Chemistry; Atmospheric chemistry
Also referred to as calcium oxide (CaO), lime, or calx. The physical appearance of CaO is white, caustic, and solid at room temperature. Calcium oxide is simply produced by heating the calcium ...
Clathrates
Chemistry; Atmospheric chemistry
Also called gas hydrates, formed by or having molecules which are interlaced in a lattice-like geometrical pattern.
Bromomethane
Chemistry; Atmospheric chemistry
CH 3 Br, a volatile compound with a high mixing rate in the atmosphere. Methyl bromide escapes easily into the atmosphere where it can contribute to the depletion of ozone in the upper atmosphere. ...
Methyl bromide
Chemistry; Atmospheric chemistry
CH 3 Br, this halocarbon is released, to a degree, naturally from the oceans, but is more commonly released from its anthropogenic use as a soil fumigant or pesticide. Methyl bromide is persistent ...
2-butanone
Chemistry; Atmospheric chemistry
CH 3 C(=O)-CH 2 CH 2 also known as methyl ethyl ketone, 2-butanone is a product of the manufacturing of paints, glues, and other finishes because of its dissolving ability. A byproduct in the ...
