What are the human health concerns? posted on 9:47 AM, June 7, 2016
Small levels of nitrogen oxides can cause nausea, irritated eyes and/or nose, fluid forming in lungs and shortness of breath. Breathing in high levels can lead to rapid, burning spasms, swelling of the throat, reduced oxygen intake, and a larger build-up of fluids in lungs and/or even death. Nitrogen oxides can contribute to ongoing respiratory issues at high levels and can also cause visual impairment.
What are the sources? posted on 9:46 AM, June 7, 2016
Nitrogen oxides form when nitrogen and oxygen in the atmosphere are burned or combusted with fossil fuels at high temperatures. These come from the burning of fossil fuels in vehicles, homes, businesses factories and power plants, from animal manure, and from agricultural/lawn management practices. Nitrous oxide is naturally produced in soils; it is increased through use of synthetic and organic fertilizers, production of nitrogen-fixing crops, cultivation of high organic content soils and application of livestock manure to croplands and pasture.

Levels of nitrogen dioxide (NO2) in Kamloops in 2015 were 12 ppb, well below many other locations in BC, such as the Lower Mainland (source: BC Lung Association). Guidelines for nitrogen dioxide from the provincial air quality objectives are 32 ppb on an annual basis.
