Is ozone at ground level considered a harmful pollutant?

Ozone at ground level is considered a harmful pollutant. It is a major component of smog and can have serious health effects, particularly for individuals with respiratory conditions, children, and the elderly. Ground-level ozone is formed when sunlight reacts with pollutants such as volatile organic compounds (VOCs) and nitrogen oxides, which are emitted from vehicles, industrial facilities, and other sources.

The incorrect choice reflects a misunderstanding of ground-level ozone's impact on air quality and public health. It is not limited to specific geographic areas or seasonal occurrences, as high concentrations can occur in various locations and times when conditions are favorable for its formation. Thus, the consensus in the field of environmental science and public health is that ground-level ozone is indeed a harmful pollutant, necessitating regulations and awareness to protect human health and the environment.
