Ammonia occurs in nature and has been detected in the interstellar medium. In many countries, it is classified as an extremely hazardous substance. [15] Ammonia is produced biologically in a process called nitrogen fixation, but even more is generated industrially by the Haber process. The process helped revolutionize agriculture by providing ...
Ammonia is toxic to aquatic life which leads to increased amounts of fish deaths. [6] Ammonia pollution also leads to eutrophication. Eutrophication is the growth of algae that kills other aquatic life and creates dead zones. Ammonia pollution affects freshwater and salt water ecosystems differently due to physical and chemical differences.
About 14,000 pounds of ammonia, which was used as a refrigerant at the frozen vegetable warehouse, was lost in the fire, the Washington Department of Ecology confirmed Tuesday to the Tri-City Herald.
Ammonium sulfate is made by treating ammonia with sulfuric acid: 2 NH 3 + H 2 SO 4 → (NH 4) 2 SO 4. A mixture of ammonia gas and water vapor is introduced into a reactor that contains a saturated solution of ammonium sulfate and about 2% to 4% of free sulfuric acid at 60 °C.
Household 'ammonia' is a solution of NH 3 in water, and is used as a general purpose cleaner for many surfaces. Because ammonia results in a relatively streak-free shine, one of its most common uses is to clean glass, porcelain, and stainless steel. It is also frequently used for cleaning ovens and for soaking items to loosen baked-on grime.
Pandora's atmosphere is a mix of nitrogen, oxygen, carbon dioxide, xenon, methane, ammonia and hydrogen sulfide, the latter three of which are unbreathable for humans, who wear Exo-Packs when outside their buildings or vehicles. The atmosphere of Pandora does have enough oxygen for humans (21–22 %), but too much carbon dioxide (16–18 %).

The dominant industrial method for producing ammonia is the Haber process also known as the Haber-Bosch process. [70] Fertilizer production is now the largest source of human-produced fixed nitrogen in the terrestrial ecosystem. Ammonia is a required precursor to fertilizers, explosives, and other products. The Haber process requires high ...
