The World Health Organization (WHO) has issued a report warning that nitrogen dioxide is “one of the main contributors to global warming” and that its presence could pose a serious threat to humans and ecosystems.
The report, which was presented at the COP21 climate conference in Marrakesh, Morocco, says that the gas “is an important contributor to CO2 and is likely to be a driver of climate change”.
But experts caution that while nitrous oxide has been widely used as a natural gas for centuries, the gas has become more potent in recent years, especially in the tropics.
Nitrous oxide is an explosive gas, which means that it has the potential to explode, leaving a crater.
In the troposphere, the explosion can create high-energy solar radiation, and could lead to global catastrophes, such as the 2010 eruption of Mount Pinatubo in the Philippines.
“Nitrous oxide can have many effects on the atmosphere, but it is important to note that it is not a greenhouse gas,” the WHO report states.
“It is an important greenhouse gas that can contribute to the climate change.”
It also points out that the tropic atmosphere is highly sensitive to greenhouse gases, such, nitrous oxides and methane.
“Because of the tropospheric ozone layer, tropospherically stratospheric concentrations of the gases in the stratosphere are likely to remain elevated for a considerable period of time,” it adds.
“This will result in more than 10 to 20 times more nitrous than the CO2 that we emit.”
In particular, nitric oxide is believed to be the main cause of the ozone hole in the Arctic.
Nitric oxide has also been blamed for a rise in coronavirus in recent times.
“In the tropopause, the atmosphere is the only region where nitrogen dioxide concentrations are higher than in the other two, because nitrogen dioxide absorbs the ultraviolet radiation,” the report says.
“Therefore, the troposteads are the only areas in the world where nitrogen-containing compounds are released from the atmosphere.”
In a previous study published in the Proceedings of the National Academy of Sciences, scientists said that nitrous gas, the main component of nitrous dioxide, could be responsible for causing CO2 emissions in the US, which are among the highest in the developed world.
In fact, the US has the second highest carbon dioxide emissions in Europe, behind Germany, and the fifth highest in Asia.
Nitrogen dioxide has also contributed to global climate change by increasing the amount of ozone in the upper atmosphere.
But the WHO warns that even in the Troposphere, where nitrogen oxides have been seen to be causing the most problems, there are still more natural processes in play, which could explain the increase in CO2.
Nitroglycerine is one of these, the WHO says.
The gas, also known as “bunker fuel”, is made by breaking up ammonium nitrate, a mixture of carbon monoxide and hydrogen sulfide.
The decomposition process releases hydrogen, and when it reaches the surface it can turn into nitroglycerin.
“At atmospheric pressure, nitrogricin is an extremely unstable gas, meaning it has very high viscosity,” the UN report states, “but because it is a stable gas it can be converted to nitroglyphosate, a common herbicide, by the reaction between ammonia and hydrogen sulphide.”
In the atmosphere around us, nitrates are found as nitrogen oxide and ammonium hydroxide, but the gas can also be made by bacteria.
In some cases, nitroso compounds are even found as nitric acid, which can cause lung and heart problems.
The WHO says that these are just a few of the chemicals in the gas that could be the source of a large part of global CO2 pollution.
“Many more chemicals can also contribute to nitrous-oxide emissions,” the organisation said.
But experts say that while there are a number of possible reasons for the rise in CO 2 in the past 20 years, one of the most likely culprits is the release of nitrogen oxates.
Nitroso oxides, which contain the same molecule as nitrous, are also the main ingredient in nitrograms, a drug used to treat respiratory infections.
According to a 2009 report from the Environmental Protection Agency, nitrophenone is one chemical that is increasing the risk of CO2 production.
It has also previously been linked to a rise of nitrosamines, a greenhouse-gas that is known to cause severe damage to the ozone layer.
“While the link between nitrogen oxidation and CO2 is strong, we still do not know the mechanisms by which nitrogen oxases can influence atmospheric CO2 levels,” the experts warn.
“For instance, how nitrosamine-producing nitrocellulose (NCP) is able to increase the amount and/or the rate of nitrate degradation is not well understood.”
They also warn that a number other factors
