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.
NO x gases are usually produced from the reaction between nitrogen and oxygen during combustion of fuels, such as hydrocarbons, in air; especially at high temperatures, such as in car engines. [ 1 ] [ 2 ] [ 3 ] In areas of high motor vehicle traffic, such as in large cities, the nitrogen oxides emitted can be a significant source of air pollution.
Liquid nitrogen is produced commercially from the cryogenic distillation of liquified air or from the liquefaction of pure nitrogen derived from air using pressure swing adsorption. An air compressor is used to compress filtered air to high pressure; the high-pressure gas is cooled back to ambient temperature, and allowed to expand to a low ...
The researchers analyzed historical data on childhood blood-lead levels, leaded gas use and U.S. population statistics, determining that more than 170 million Americans had "clinically concerning ...
An example of traumatic asphyxia is a person who jacks up a car to work on it from below, and is crushed by the vehicle when the jack fails. [7] Constrictor snakes such as boa constrictors kill through slow compressive asphyxia, tightening their coils every time the prey breathes out rather than squeezing forcefully.
The recall consists of some Beetle and Passat vehicles from model years 2006-2019. "The driver's side frontal airbag inflator may explode due to propellant degradation occurring after long-term ...
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.
A recent study by the University of Southern California revealed that exposure to air pollution can harm children's learning and memory, the LA Post reports.. Ammonium nitrate, a specific ...
