Nitric oxide is a colorless, flammable gas with a slight odor. Nitrogen dioxide is a deep red-orange gas that is poisonous but not flammable. It, along with aerosols, is responsible for the reddish-brown color of smog. At high concentrations it is highly toxic, and can cause serious lung damage.
Nitrogen dioxide is a strong oxidizing agent, and is thus very reactive with other compounds. Scientists estimate that nature produces between 20 and 90 million tons of nitrogen oxides on Earth each year.
Natural sources include volcanoes, oceans, biological decay, and lightning strikes. Human activities add another 24 million tons of nitrogen oxides to our atmosphere annually. Four representations chemists use for nitrogen dioxide NO 2. The European Commission can take action against any Member State if the air quality does not meet the Limit Values throughout its territory.

Part of BMI Group. Skip to navigation. What is it? See our video on how the Noxite solution depollutes the built environment Nitrogen dioxide is an irritant gas, which at high concentrations causes inflammation of the airways.
Sources of NOx Pollution NOx is produced from the reaction of nitrogen and oxygen gases in the air during combustion, especially at high temperatures. NOx emissions in the EU -share of emissions by sector group, The pie chart below shows that road transport and energy production are the greatest sources of NOx emissions in the EU during 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 about 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 the 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. She enjoys guiding them to find the right solution to help them understand the air they breathe.

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 several oxides of nitrogen. NOx can be from natural, biogenic and industrial sources Natural sources: Mainly thunderstorms due to the extreme heat of lightning. The impact of NOx to humans and environment How does the presence of nitrogen oxides impact me?
Are there any adverse effects on my health and should I be concerned? Does it impact the environment? What causes NO 2 air pollution? Is the air we breathe safe?
