NOx (nitrogen oxides)

Nitrogen oxides (NOx) are a group of gases composed of nitrogen and oxygen, primarily produced during combustion processes, such as in vehicles, power plants, and industrial facilities. NOx plays a significant role in air pollution, contributing to the formation of smog and acid rain, which can harm health, ecosystems, and infrastructure. It can cause respiratory problems and exacerbate conditions like asthma. Reducing NOx emissions is important for improving air quality and protecting public health, leading to stricter regulations and the development of cleaner technologies in transportation and energy production.
