		Dinitrogen oxide is rapidly detected when nitrification starts to fail, and the rate of this off-gas production is linked to oxygen depletion, the presence of toxic substances, and ammonia shock loadings.
		The occurrence of dinitrogen oxide under standard stable process conditions is normal in the denitrification part of the activated sludge process, but this occurrence is short lived and at very low concentrations.
		At ‘5 m’ average dinitrogen oxide concentrations declined and were found to be less than 0.9 mg/l up to 46 hours into the trial, with low levels maintained apart from a 2.1 mg/l peak (84 hours), a peak of 1.8 mg/l (107 hours), and a minor increase to 0.9 mg/l (138 hours).

	IGAC \| Nitrous Oxide Emissions from Agriculture
		Because of the uncertainty in knowing the amount of dinitrogen fixed during N-fixation (Peoples et al., 1995) and the lack of country data on N-fixing crops, it is difficult to assign a conversion factor to nitrous oxide emission that is related to the amount of N fixed by a crop.
		This new approach to estimating nitrous oxide emissions from agricultural systems includes: (1) direct emissions of nitrous oxide from agricultural fields; (2) direct emissions of nitrous oxide in animal production systems and, (3) some of the indirect emission of nitrous oxide that are derived from N that originated from agricultural systems.

		Nitrous oxide, also known as dinitrogen oxide or dinitrogen monoxide, is a chemical compound with chemical formula N2O (2 atoms of nitrogen and 1 atom of oxige).
		Nitrous oxide allows the engine to burn more fuel at a lower rpm range than normal, this way a longer burning period is created and the pistons will be pushed down with a greater average force.
		In the nitrous oxide molecule the atoms are boud together, so the oxygen is not free but the bond breaks down as temperature rises (arround 565° F).

		Nitrous oxide is used as a foaming agent and propellant in whipped cream.
		Nitrous oxide dissolves in the fats that sheath the nerve cells, and produces numbing and mild intoxication.
		Other possible propellants, such as the propane used in hair sprays, or freon, also cause intoxication when they dissolve in the fats around nerve cells, and so are not used, since their flammability, safety, cost, or taste makes them less desirable than nitrous oxide for whipping cream.
