Heat capacity of anhydrous liquid ammonia. Uses polynomial obtained from CHERIC. [8] Spectral data ... Explosive limits: 15–28% RTECS # BO0875000 Safety data sheet
Much is still unknown about the impact of ammonia pollution, but rising emission rates concern scientists. The level of ammonia in the atmosphere was more than twice as large in 2010 as it was in 1940. [8] Ammonia is now recognized by many countries as a major pollutant and some have begun taking steps to limit their emissions. [7]

Ammonia electrolysis may require much less thermodynamic energy than water electrolysis (only 0.06 V in alkaline media). [23] Another option for recovering ammonia from wastewater is to use the mechanics of the ammonia-water thermal absorption cycle. [24] [25] Ammonia can thus be recovered either as a liquid or as ammonium hydroxide. The ...
Emissions or release parameters such as source location and height, type of source (i.e., fire, pool or vent stack) and exit velocity, exit temperature and mass flow rate or release rate. Terrain elevations at the source location and at the receptor location(s), such as nearby homes, schools, businesses and hospitals.
Regulations that define and limit the concentration of pollutants in the ambient air or in gaseous emissions to the ambient air are issued by various national and state (or provincial) environmental protection and occupational health and safety agencies. Such regulations involve a number of different expressions of concentration.
Map showing Convention on Long-Range Transboundary Air Pollution signatories (green) and ratifications (dark green) as of July 2007. The 1999 Gothenburg Protocol to Abate Acidification, Eutrophication and Ground-level Ozone (known as the Multi-effect Protocol or the Gothenburg Protocol) is a multi-pollutant protocol designed to reduce acidification, eutrophication and ground-level ozone by ...
