A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. [1] In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas , methane , propane , butane .
Ecological impacts of explosives are the effects that both unexploded explosives and post-explosion by-products have on the environment. [1] Explosive derived contaminants may have adverse effects on the environmental as well as human health. In addition to their military use in warfare, explosives are also used in construction and demolition.
A dust explosion is the rapid combustion of fine particles suspended in the air within an enclosed location. Dust explosions can occur where any dispersed powdered combustible material is present in high-enough concentrations in the atmosphere or other oxidizing gaseous medium, such as pure oxygen .
A relatively new technology that can mitigate air pollution is called bio-filtration. Bio filtration is where off-gasses that have biodegradable VOCs or inorganic air toxins are vented out through a biologically active material. [82] This technology successfully used in Germany and the Netherlands mainly for odor control.
Growing air pollution in southeast New Mexico was tied to surging oil and gas production via an ongoing study in the Carlsbad area.
Plumes are of considerable importance in the atmospheric dispersion modelling of air pollution. A classic work on the subject of air pollution plumes is that by Gary Briggs. [4] [5] A thermal plume is one which is generated by gas rising above a heat source. The gas rises because thermal expansion makes warm gas less dense than the surrounding ...
Particulate pollution is pollution of an environment that consists of particles suspended in some medium. There are three primary forms: atmospheric particulate matter, [1] marine debris, [2] and space debris. [3] Some particles are released directly from a specific source, while others form in chemical reactions in the atmosphere.
Since a large share of air pollution is caused by combustion of fossil fuels such as coal and oil, the reduction of these fuels can reduce air pollution drastically. Most effective is the switch to clean power sources such as wind power , solar power , hydro power which do not cause air pollution. [ 286 ]
