Climate-driven extreme weather conditions, such as droughts and intense precipitation, may be accelerating the pace at which toxic nitrates are polluting groundwater, a recent study has found.
In the NO − 3 anion, the oxidation state of the central nitrogen atom is V (+5). This corresponds to the highest possible oxidation number of nitrogen. Nitrate is a potentially powerful oxidizer as evidenced by its explosive behaviour at high temperature when it is detonated in ammonium nitrate (NH 4 NO 3), or black powder, ignited by the shock wave of a primary explosive.

Calcium ammonium nitrate Is a blend of 20-30% limestone CaCO 3 or dolomite (Ca,Mg)CO 3 and 70-80% ammonium nitrate with 24-28 % nitrogen. Calcium nitrate with 15,5% nitrogen and 19% calcium, reportedly holding a small share of the nitrogen fertilizer market (4% in 2007).
The cause of the explosion was the ignition of ammonium nitrate used as raw material for fertilizer and explosives. Australia Taroom, Queensland August 30, 1972: 3 12 In the 1972 Taroom explosion, a truck carrying 12 tons of ammonium nitrate experienced an electrical fault and caught fire north of Taroom, Queensland. After the driver stopped ...
The devastating explosion in Beirut should be a wake-up call for countries on the dangers of ammonium nitrate, which caused the blast, experts say. Lebanese authorities said 2,750 tonnes of the ...
nitrates are the most abundant pollutants in the Central Valley due to the copious amounts of agricultural runoff from the farms. [2] The concentration of naturally occurring arsenic is also an issue. [3] Manganese has been detected at concerning levels, posing health risks especially to young children and pregnant women due to its neurotoxic ...
Brunton found that amyl nitrites had effects of dilating blood vessels and flushing of the face. Isobutyl nitrites were also documented around the late 1890s by Brunton and despite being found to have generally the same effects as amyl nitrites, they were never used as a clinical alternative to amyl nitrates.
