NOxként

NOxként is a term that refers to various nitrogen oxides. The most common forms are nitric oxide (NO) and nitrogen dioxide (NO2). These gases are often grouped together because they are frequently produced simultaneously and can interconvert in the atmosphere. NOx is a significant air pollutant with a variety of sources.

One of the primary sources of NOx is the combustion of fossil fuels. High temperatures within engines of vehicles and in industrial power plants cause atmospheric nitrogen and oxygen to react. Natural sources of NOx include lightning strikes and microbial activity in soils.

NOx plays a crucial role in atmospheric chemistry. It contributes to the formation of ground-level ozone, a major component of smog, which can have detrimental effects on human respiratory health and damage vegetation. Furthermore, NOx can lead to acid rain when it reacts with water and oxygen in the atmosphere, forming nitric acid. This acid can then fall to the Earth's surface, impacting ecosystems and infrastructure.

Regulations and emission control technologies have been implemented in many countries to reduce NOx emissions from industrial and mobile sources. These efforts aim to mitigate the negative impacts of NOx on air quality and public health.
