Nitrogen dioxide poisoning is the illness resulting from the toxic effect of nitrogen dioxide (NO 2). It usually occurs after the inhalation of the gas beyond the threshold limit value. [1] Nitrogen dioxide is reddish-brown with a very harsh smell at high concentrations, at lower concentrations it is colorless but may still have a harsh odour.
About 40% of human-caused emissions are from agriculture, [11] [12] as nitrogen fertilisers are digested into nitrous oxide by soil micro-organisms. [13] As the third most important greenhouse gas, nitrous oxide substantially contributes to global warming. [14] [15] Reduction of emissions is an important goal in the politics of climate change. [16]
Nitrogen dioxide is poisonous and can be fatal if inhaled in large quantities. [8] Cooking with a gas stove produces nitrogen dioxide which causes poorer indoor air quality. Combustion of gas can lead to increased concentrations of nitrogen dioxide throughout the home environment which is linked to respiratory issues and diseases.
An occasional cause of accidental death in humans, inert gas asphyxia has been used as a suicide method. Inert gas asphyxia has been advocated by proponents of euthanasia, using a gas-retaining plastic hood device colloquially referred to as a suicide bag. Nitrogen asphyxiation has been approved in some places as a method of capital punishment.
Nitrogen oxides are released during manufacturing of nitrogen fertilizers. Though nitrous oxide is emitted during its application, it is then reacted in atmosphere to form nitrogen oxides. This third source is attributed to the reaction of atmospheric nitrogen, N 2 , with radicals such as C, CH, and CH 2 fragments derived from fuel, [ 26 ...
Because no person has ever been executed by inhaling pure nitrogen, how the state will carry out a nitrogen hypoxia execution remains unclear. Nitrogen hypoxia to execute a human: 'Bloodless, but ...
Dr Zivot cites studies that have shown the use of nitrogen gas to deprive healthy humans of oxygen and that after 15 or 20 seconds, around 80 per cent of participants had seizures.
Nitrous oxide has no acute biochemical or cellular toxicity and is not metabolized in humans or other mammals. Rare deaths and injuries associated with use are due to asphyxia or accidents while under the influence, or vitamin B 12 deficiency. Excessive use can lead to long-term and significant neurological and haematological toxicity. [2] [3]
