Nitric oxide (NO) is considered a major pollutant because it contributes to the formation of ground-level ozone and smog, which can have detrimental effects on human health and the environment. It is primarily produced from combustion processes, such as those in vehicles and power plants. Additionally, NO can lead to the formation of nitrogen dioxide (NO2), which is harmful to respiratory systems and can exacerbate Asthma and other health issues. Its presence in the atmosphere can also contribute to acid rain and the degradation of ecosystems.
