Although relatively small amounts are released, it has a high "global warming potential" (310 times that of carbon dioxide). Nitrous oxide also damages the ozone layer, thus reducing the protection offered from harmful UV sun rays. At normal environmental concentrations, nitrous oxide is not harmful to humans.
Subsequently, one may also ask, why is nitrogen dioxide bad for the environment?
Nitrogen dioxide is part of a group of gaseous air pollutants produced as a result of road traffic and other fossil fuel combustion processes. Its presence in air contributes to the formation and modification of other air pollutants, such as ozone and particulate matter, and to acid rain. More
How does nitrogen dioxide affect human health and the environment?
The main effect of breathing in raised levels of nitrogen dioxide is the increased likelihood of respiratory problems. Nitrogen dioxide inflames the lining of the lungs, and it can reduce immunity to lung infections. This can cause problems such as wheezing, coughing, colds, flu and bronchitis.
How does nitrogen affect the environment?
There are two main things that these nitrogen compounds affect: the environment and human health. This can be caused by nitrogen oxides in the atmosphere. As well as its tricks with ozone, nitrogen oxides dissolve in atmospheric water to make acid rain, which corrodes stone and metal work and damages buildings.
