The most commonly used grade of these fertilizer solutions is UAN 32.0.0 (32%N) known as UN32 or UN-32, which consists of 45% ammonium nitrate, 35% urea and only 20% water. Other grades are UAN 28, UAN 30 and UAN 18.
Diesel exhaust fluid (DEF; also known as AUS 32 and sometimes marketed as AdBlue [3]) is a liquid used to reduce the amount of air pollution created by a diesel engine. Specifically, DEF is an aqueous urea solution made with 32.5% urea and 67.5% deionized water .
"Nitrox 32", or EAN 32, would be a nitrox blend with 32% oxygen and 68% nitrogen. This is a popular recreational blend for dives to depths up to 33 metres (108 ft). The nitrogen in the mixture is almost always provided by topping up the cylinder with air to the filling pressure.
The size of fertilizer particles may also be varied in order to vary the time at which nitrogen release occurs. Sulfur-coated products typically range from 32% to 41% elemental nitrogen by weight. The sulfur coating process was originally developed by the Tennessee Valley Authority. [1]
Trimix scuba cylinder label IMCA Trimix cylinder shoulder colour code alternative IMCA Trimix cylinder shoulder colour code. Trimix is a breathing gas consisting of oxygen, helium and nitrogen and is used in deep commercial diving, during the deep phase of dives carried out using technical diving techniques, [1] [2] and in advanced recreational diving.
But they emit 32% of health-threatening particulate matter from the state’s vehicles and 26% of nitrogen oxides, which form smog, Cooper’s office said in a release.
[3] [21] Since the word is a compound contraction or coined word and not an acronym, it should not be written in all upper case characters as "NITROX", [3] but may be initially capitalized when referring to specific mixtures such as Nitrox32, which contains 68% nitrogen and 32% oxygen. When one figure is stated, it refers to the oxygen ...
Specific pollutant exposures, such as high levels of nitrogen dioxide, have been cited in community-led complaints relating to increased emergency room visits for respiratory issues. [ 39 ] [ 40 ] Potential health effects of waste incineration technology have been publicized, notably when located in communities already facing disproportionate ...
