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.
Human activities account for over one-third of N 2 O emissions, most of which are due to the agricultural sector. [2] This article is intended to give a brief review of the history of anthropogenic N inputs, and reported impacts of nitrogen inputs on selected terrestrial and aquatic ecosystems.
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.
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.
Toxic: a chemical that has a median lethal concentration (LC 50) in air of more than 200 parts per million (ppm) but not more than 2,000 parts per million by volume of gas or vapor, or more than 2 milligrams per liter but not more than 20 milligrams per liter of mist, fume or dust, when administered by continuous inhalation for 1 hour (or less if death occurs within 1 hour) to albino rats ...
To decrease the risk of asphyxiation, there have been proposals to add warning odors to some commonly used gases such as nitrogen and argon. However, CGA has argued against this practice. They are concerned that odorizing may decrease worker vigilance, not everyone can smell the odorants, and assigning a different smell to each gas may be ...
Narcosis results from breathing gases under elevated pressure, and may be classified by the principal gas involved. The noble gases, except helium and probably neon, [2] as well as nitrogen, oxygen and hydrogen cause a decrement in mental function, but their effect on psychomotor function (processes affecting the coordination of sensory or cognitive processes and motor activity) varies widely.
