Other bacteria may then consume free H2, which may also be oxidised photochemically in the atmosphere or lost to space. Hydrogen is also thought to be an important reactant in pre-biotic chemistry and the early evolution of life on Earth, and potentially elsewhere in the Solar System .
The Environmental Psychology Research Group (EPRG) within the University of Surrey, of which students on the M.Sc in Environmental Psychology are automatically members, has been undertaking research for more than thirty years. EPRG's mission is to gain a better understanding of the environmental and psychological effects of space, no matter the ...
In 1987 in the village of Bourakebougou in Mali, Africa, a worker attempted to light his cigarette next to a certain water well, and the well unexpectedly caught fire. A local entrepreneur soon became interested in the possible economic value of this "burning well" and determined that the flames were produced by natural hydrogen seeping out of ...
High pressure electrolysis is the electrolysis of water by decomposition of water (H 2 O) into oxygen (O 2) and hydrogen gas (H 2) by means of an electric current being passed through the water. The difference with a standard electrolyzer is the compressed hydrogen output around 120–200 bar (1740–2900 psi , 12–20 MPa ). [ 146 ]
Environmental chemistry is used by the Environment Agency in England, Natural Resources Wales, the United States Environmental Protection Agency, the Association of Public Analysts, and other environmental agencies and research bodies around the world to detect and identify the nature and source of pollutants. These can include:
Air pollution — Atmospheric particulate matter • Biological effects of UV exposure • CFC • Environmental impact of the coal industry • Environmental impact of hydraulic fracturing • Indoor air quality • Ozone depletion • Smog • Tropospheric ozone • Volatile organic compound • Ultrafine particles Light pollution Noise pollution
Behavioral sink" is a term invented by ethologist John B. Calhoun to describe a collapse in behavior that can result from overpopulation. The term and concept derive from a series of over-population experiments Calhoun conducted on Norway rats between 1958 and 1962. [1]
Water pollution is an environmental issue that affects many water bodies. This photograph shows foam on the New River as it enters the United States from Mexico. Environmental issues are disruptions in the usual function of ecosystems. [1] Further, these issues can be caused by humans (human impact on the environment) [2] or they can be natural ...
