Ammonium nitrate is a chemical compound with the formula NH4NO3. It is a white crystalline salt consisting of ions of ammonium and nitrate. It is highly soluble in water and hygroscopic as a solid, although it does not form hydrates. It is predominantly used in agriculture as a high-nitrogen fertilizer.
The environmental effects of irrigation relate to the changes in quantity and quality of soil and water as a result of irrigation and the subsequent effects on natural and social conditions in river basins and downstream of an irrigation scheme. The effects stem from the altered hydrological conditions caused by the installation and operation ...
Elevated nitrate in groundwater is a concern for drinking water use because nitrate can interfere with blood-oxygen levels in infants and cause methemoglobinemia or blue-baby syndrome. Where groundwater recharges stream flow, nitrate-enriched groundwater can contribute to eutrophication , a process that leads to high algal population and growth ...
Once nitric oxide is converted to nitrates and nitrites by oxygen and water, cell signaling is deactivated. [27] The endothelium (inner lining) of blood vessels uses nitric oxide to signal the surrounding smooth muscle to relax, resulting in vasodilation and increasing blood flow. [26] Sildenafil (Viagra) is a drug that uses the nitric oxide ...
Nitrate levels above 10 mg/L (10 ppm) in groundwater can cause 'blue baby syndrome' (acquired methemoglobinemia). [82] The nutrients, especially nitrates, in fertilizers can cause problems for natural habitats and for human health if they are washed off soil into watercourses or leached through soil into groundwater. [83]
The Environmental Protection Agency has set a maximum of 10 mg/L nitrate concentration in drinking and surface waters. When nitrogen in the form of nitrate is in excess, it can lead to a dead zone. A dead zone is a body of water that has a depleted oxygen concentration that is low and can lead to the suffocation of animals.
Infobox references. Nitrate is a polyatomic ion with the chemical formula NO−. 3. Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. [1] Almost all inorganic nitrates are soluble in water. An example of an insoluble nitrate is bismuth oxynitrate .
A nitrate vulnerable zone is a conservation designation of the Environment Agency for areas of land that drain into nitrate polluted waters, or waterways that could become polluted by nitrates due to environmental and health threats. A nitrate vulnerable zone can be designated as a response to an increase in nitrate leaching or increased use of ...
