Meet nitrogen, commonly referred to simply with the chemical symbol N. When two nitrogen atoms bond together, they form nitrogen gas N 2.

Nitrogen oxide gas

Nitrogen gas is odourless, colourless and tasteless. It is non-flammable and will not support combustion. You probably remember learning about the nitrogen cycle in school and how it is crucial to all life on earth.

At normal pressure and temperature, molecules of oxygen bind to form dioxygen O Nitrogen oxide gas which is present in the atmosphere. Oxygen is the third most abundant element in the universe, and of course is crucial to our continued existence. Interesting fact: the most common auroral colour pale yellowish-green in the northern lights is produced by oxygen molecules located about 60 miles above the earth.

How cool is that! At room temperature, nitrogen is a very inactive gas — a couch potato, you might say.

But sparks can fly between these two. In the presence of lightning or a spark, nitrogen combines with oxygen to form several different oxides. Nitrogen monoxide or nitric oxide NO and nitrogen dioxide NO 2 are the most abundant. NO x molecules have nitrogen and oxygen atoms in them. Nitrogen oxides are produced from the reaction of nitrogen and oxygen gases in the air during combustion, especially at high temperatures.

At normal temperatures, oxygen and nitrogen gases do not react together. Nitrogen oxides are produced naturally from a lightning strike. A bolt of lightning can reach temperatures of roughly 30, kelvins 53, degrees Fahrenheit. How many times does lighting strike the earth you might ask? In large cities, nitrogen oxides are produced from fuel combustion in mobile and stationary sources. The combustion of gasoline in automobiles emit nitrogen oxides into the atmosphere mobile source. Stationary emissions come from Nitrogen oxide gas fired power plants, electric power plant boilers.

Natural sources: Mainly thunderstorms due to the extreme heat of lightning. Forest fire is another natural source. Biogenic: Agricultural fertilization and the use of nitrogen fixing plants through nitrogen fixation by microorganisms.

Although naturally produced nitrogen oxides outweigh man-made emissions, NOx from natural sources are typically found at altitudes higher than 5km. Nitrogen oxides NO x react to form smog and acid rain. NO x reacts with ammonia, Nitrogen oxide gas and other compounds to form nitric acid vapour and related particles.

The impacts of NO x on human health include damage to the lung tissue, breathing and respiratory problems.

Nitric oxide NO is not considered to be hazardous to health at typical ambient conditions. However, excess Nitrogen oxide gas oxide and its products may cause respiratory ailments, hematologic side effects, metabolic disorders, low blood pressure, nausea, vomiting and diarrhoea. Nitrogen dioxide NO 2 at high concentrations causes inflammation of the airways.

Breathing in high levels of NO 2 can increase the likelihood of respiratory problems: wheezing, coughing, colds, flu and bronchitis. People with asthma are prone to have more intense attacks. Prolonged exposure to high levels of NO 2 can cause irreversible damages to the respiratory system. High levels of NOx can have a negative effect on vegetation by making it more susceptible to disease and frost damage.

When NOx reacts with other pollutants in the presence of sunlight, it forms ozone. Ozone at high concentrations also damage vegetation. Air pollution occurs when gases, dust particles, fumes or odour are introduced into the atmosphere which has harmful or poisonous effects.

The common air pollutants are also known as criteria Nitrogen oxide gas :. The amount of nitrogen oxides emitted into the atmosphere as air pollution, from both man-made sources, can be quite ificant.

While NO 2 is a primary pollutant, it is also a contributing component for secondary pollutants formed from a chemical reaction. The most common is ozone. Photochemical smog, most common in sunny, dry locations, is created when NO 2 from gas combustion is exposed to sunlight, splits and releases an oxygen ion O. The released O combines with oxygen molecule O 2 forming ozone O 3.

Ozone is one of the major secondary pollutants. You can about ozone pollution in our blog: Why do I have an ozone pollution problem and what can I do about it? Indoor NO 2 levels are a result of both indoor and outdoor sources. While indoor NO 2 is produced by unvented heaters and gas stoves, high outdoor NO 2 levels originating from local traffic and other combustion sources can influence indoor levels. Air pollution is a serious problem and we should all be concerned.

Worldwide, more deaths per year are linked to air pollution than to automobile accidents. NO 2 is both a primary and secondary pollutant. Air pollution impacts everyone but some of us are more susceptible than others: children and seniors, people with existing lung and heart conditions, people working and exercising outdoors. To combat the serious health effects it is important to find out more Nitrogen oxide gas air pollution, such as areas of heavy concentration, elements of composition and cause.

To get this information, comprehensive air quality monitoring must be undertaken using air monitoring devices, such as shown below. These can be portable, ideal for checking pollution hot-spots or personal exposure, or fixed monitors, which measure Nitrogen oxide gas air continuously so you know when NO 2 levels are high.

Both measure the air in real-time giving you accurate readings to make informed decisions. Portable monitors to measure NO 2. Aeroqual makes sensors and equipment for air quality monitoring. Monitoring NO 2 and other pollutants is easy as See our portable outdoor air quality monitors to learn more.

Nitrogen oxides NO x is a collective term used to refer to nitrogen monoxide nitric oxide or NO and nitrogen dioxide NO 2 Nitrogen monoxide NO is a colourless gas and one of the principal oxides of nitrogen Nitrogen dioxide NO 2 is a reddish-brown gas with a pungent, acrid odour and one of the Nitrogen oxide gas oxides of nitrogen.
