"Nitrogen oxide" refers to a gas made up of nitrogen and oxygen molecules. It is produced by various sources, such as car engines and power plants, and contributes to air pollution.
Full definition
This suggests, he says, that
nitrogen oxide emissions from transport and industry are increasing more rapidly than ammonia emissions from agriculture.
But near the poles and in the upper stratosphere, CO2 is increasing the amount of ozone by preventing
nitrogen oxide from breaking it down.
So its amount depends not only on temperature and amount of sunshine but also the presence of precursor gases such
as nitrogen oxide.
According to the study, regional emissions dropped 65 percent
for nitrogen oxide, 92 percent for sulfur dioxide and 35 percent for carbon dioxide between 2005 and 2014.
This study documents actual levels of destruction, by taking readings of ozone and
nitrogen oxide levels before and during the event.

nitrogen oxide emissions by 70 percent, while electricity generation has increased 40 percent.
All diesel engines will employ exhaust gas treatment technology including a diesel particulate filter, NOX absorber catalyst and SCR (Selective Catalytic Reduction) system, which uses urea solution (AdBlue) injection to effectively
reduce nitrogen oxides in the car's exhaust gases.
Gas - fired power stations release about half the CO2 (per MWh of electricity) that coal stations produce and they also release
nitrogen oxides into the atmosphere.
More lightning also would likely generate
more nitrogen oxides in the atmosphere, which exert a strong control on atmospheric chemistry.
With all that renewable energy comes over 100,000 jobs, and a huge reduction in carbon dioxide (27 million pounds of CO2 that is not emitted by power plants) and a reduction in smog
producing nitrogen oxides and the health threatening fine particulate matter.
CO2 from ships makes up roughly 3 percent of all human - emitted CO2 and almost 30 percent of smog -
forming nitrogen oxide gases.
German engineering giant announces new technology it claims will
cut nitrogen oxide emissions for diesel cars to a fraction of 2020 limits

nitrogen oxide gases in the state, new research finds.
Then, again with the diesel, harmful
nitrogen oxides came into focus, which was (supposedly) tackled with complicated exhaust after - treatment systems.
Meanwhile, existing coal - fired power plants, many of which date to the 1970s or earlier, will continue to face pressure to close as other environmental regulations target conventional coal pollutants
like nitrogen oxides, mercury and particulate matter.
Ozone pollution occurs
when nitrogen oxides from motor vehicle exhaust, industrial and power station emissions react with volatile organic compounds in the air.
The Fraser Institute study found that the coal phase - out had no apparent effect
on nitrogen oxide levels.
Neff W. D., J. Crawford, M. Buhr, J. Nicovich, G. Chen and D. Davis (March 2018): The meteorology and chemistry of high
nitrogen oxide concentrations in the stable boundary layer at the South Pole.
Smog -
causing nitrogen oxides from the Los Angeles port's ships declined 30 percent between 2005 and 2011, while particulate matter decreased about 70 percent.
It is almost three years since VW was caught fitting cheat devices to fool testers into measuring lower than actual levels of
nitrogen oxides emitting from its diesel cars.
The transport and other special lobbies are much happier to talk
about nitrogen oxides — which are probably less dangerous and certainly more easily reduced.
Keeping all those trees happy, however, is Audi's high efficiency SCR system that
removes nitrogen oxides from the exhaust.
Ozone is an odorless gas that is not directly emitted into the air but is created by chemical reactions
between nitrogen oxides (NOx) and volatile organic compounds (VOC)-- which occur naturally but are also produced from the burning of fossil fuels and are released in the process of drilling for oil and natural gas.
Shares in German carmaker plunge 9 % as reports claim BMW xDrive 20d tops
nitrogen oxide limits more than elevenfold
Scientists examined the chemistry of brown carbon and found that
increased nitrogen oxide levels result in particles that hold significantly more heat and cause the atmospheric mix to turn a familiar yellowish brown.
Nowadays, in - engine measures for optimizing combustion management permit the minimization of particles and
nitrogen oxides at reduced consumption and higher output.
«To ask the Secretary of State for Transport whether he has requested a derogation from EU air quality legislation in relation to limits on the levels of pollution from (a) nitrogen dioxide, (b) ozone and (c)
other nitrogen oxides.
It then combines with pollutants from combustion —
mainly nitrogen oxides and sulfates from vehicles, power plants and industrial processes — to create tiny solid particles, or aerosols, no more than 2.5 micrometers across, about 1/30 the width of a human hair.
«The existing plant has outrageously
high nitrogen oxide and particulate emissions, which contribute to ground - level ozone and exacerbate asthma.
According to the U.S. Environmental Protection Agency, the process of manufacturing glass not only contributes its share of greenhouse gas emissions but also
generates nitrogen oxides, sulfur dioxide and tiny particulates that can damage lung tissue when breathed in.
(D) combustion technology to produce higher firing temperature while
lowering nitrogen oxide and carbon monoxide emissions per unit of output;
Researchers from the University of Los Angeles recently found that pomegranate juice is an effective tool that
protects nitrogen oxide from oxidative destruction.
Power is provided by the world's cleanest diesel technology: the 3.0 - litre V6 TDI clean diesel almost completely
eliminates nitrogen oxides.
The breakthrough «SKYACTIV - D 2.2» is the world's first passenger vehicle diesel engine to pass Japan's Post New Long - Term Emissions Regulations without the need for
expensive nitrogen oxide (NOx) aftertreatment technology.
