Nitrogen oxides is only composed of two elements nitrogen, oxygen compounds. Nitrogen oxides as air pollutants is the floorboard of NO and NO2, with NOx said. NOx is one of the main atmospheric pollutants, directly or indirectly related to the atmospheric environmental problems, such as photochemical smog, acid precipitation, stratospheric ozone depletion and global climate change. In addition, the increased amount of nitrogen deposition can lead to the eutrophication of surface water and on land, wetlands, underground drainage acidification and poison, cause damage to terrestrial and aquatic ecosystems, eventually harmful to human health and ecological environment security.
Nitric oxide as a pollutant, itself can cause harm to human body health, it can stimulate people's eyes, nose, throat, and lungs, easy to cause the respiratory system disease, such as cause bronchitis and pneumonia caused by influenza, induced lung cancer; For children, nitrogen oxides may cause damage to the lung development.
Nitrogen also produces a variety of secondary pollution. It is one of the important material to generate ozone, closely related to the ozone concentration and light chemical pollution. Ozone will stimulate the eyes and respiratory tract, and lead to damage of agricultural production, cultural relics and so on. Due to ozone formation and material is easy to transport, diffusion in the atmosphere, the photochemical smog often become a regional problem, the coverage can reach more than dozens or even hundreds of kilometers, and the ozone concentration in suburban and rural areas are often higher than the city.
