NOxkonsentraatioon

NOxkonsentraatioon refers to the concentration of nitrogen oxides (NOx) in a given medium, typically the atmosphere. Nitrogen oxides are a group of gases primarily composed of nitric oxide (NO) and nitrogen dioxide (NO2). These compounds are formed during high-temperature combustion processes, such as those occurring in vehicle engines, industrial power plants, and other combustion sources. They can also be produced naturally through lightning and microbial activity in soil.

Measuring NOxkonsentraatioon is important for environmental monitoring and public health assessments. High concentrations of NOx in the atmosphere contribute to air pollution. Nitrogen dioxide, in particular, is a respiratory irritant and can exacerbate conditions like asthma. Furthermore, NOx plays a significant role in the formation of ground-level ozone, a major component of smog, and acid rain. Acid rain can damage ecosystems, buildings, and infrastructure.

The units used to express NOxkonsentraatioon can vary, but common ones include parts per million (ppm), parts per billion (ppb), micrograms per cubic meter (µg/m³), and milligrams per cubic meter (mg/m³). Regulatory bodies often set air quality standards based on maximum permissible NOxkonsentraatioon to protect human health and the environment. Efforts to reduce NOx emissions from various sources are a key aspect of air quality management strategies worldwide.
