What is one negative effect of nitrogen oxides on air quality?

One significant negative effect of nitrogen oxides on air quality is the formation of ground-level ozone. Nitrogen oxides are reactive gases that are released during combustion processes, such as those in vehicles and power plants. When these gases react with volatile organic compounds in the presence of sunlight, they contribute to the formation of ozone at ground level.

Ground-level ozone is a major component of smog and can have serious health implications, including respiratory problems, reduced lung function, and exacerbation of asthma. It can also harm vegetation and ecosystems, negatively affecting air quality and overall environmental health. Thus, the connection between nitrogen oxides and the formation of ground-level ozone highlights a clear detrimental impact on air quality.
