NO2lles

NO2lles, also known as nitrogen dioxide, is a chemical compound with the formula NO2. It is a reddish-brown gas that is a prominent air pollutant. NO2 is formed through the oxidation of nitric oxide (NO) in the atmosphere, primarily from the combustion of fossil fuels in vehicles and industrial processes. It is a significant contributor to smog and acid rain, and is also a key precursor to the formation of ozone (O3) in the troposphere.

NO2 is a respiratory irritant and can cause a range of health issues, including respiratory infections, bronchitis, and aggravation of asthma. Prolonged exposure can lead to more severe health problems, such as reduced lung function and increased risk of respiratory diseases. The World Health Organization (WHO) has set guidelines for NO2 concentrations in outdoor air, recommending an annual mean not to exceed 40 micrograms per cubic meter (μg/m3).

Efforts to reduce NO2 levels include the implementation of stricter emission standards for vehicles, the promotion of alternative fuels, and the development of technologies to capture and reduce NO2 emissions from industrial sources. Monitoring and regulation of NO2 levels are essential to protect public health and the environment.
