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.
Nitrogen dioxide is a chemical compound with the formula NO2. One of several nitrogen oxides, nitrogen dioxide is a reddish-brown gas. It is a paramagnetic, bent molecule with C 2v point group symmetry. Industrially, NO2 is an intermediate in the synthesis of nitric acid, millions of tons of which are produced each year, primarily for the ...
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA or STEL) determined by the ACGIH professional association.
Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bond to form N 2, a colorless and odorless diatomic gas.
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.
2O charger (bottom right), cracker (top right) and balloon. 3 liter can of recreational nitrous oxide to fill up balloons. Nitrous oxide (street name nangs, hippy crack, whippets, whippits or cannies) is a gas which can induce euphoria, hallucinogenic states and relaxation when inhaled. [ 1] Nitrous oxide is a neurotoxin and excessive use can ...
In atmospheric chemistry, NOx is shorthand for nitric oxide ( NO) and nitrogen dioxide ( NO2 ), the nitrogen oxides that are most relevant for air pollution. [ 1][ 2] These gases contribute to the formation of smog and acid rain, as well as affecting tropospheric ozone . NOx gases are usually produced from the reaction between nitrogen and ...
Decompression sickness ( DCS; also called divers' disease, the bends, aerobullosis, and caisson disease) is a medical condition caused by dissolved gases emerging from solution as bubbles inside the body tissues during decompression. DCS most commonly occurs during or soon after a decompression ascent from underwater diving, but can also result ...
