Summary:
- Ground-level ozone, a key component of smog, can have negative impacts on public health, especially for vulnerable populations like children and the elderly.
- Ozone is formed when nitrogen oxides and volatile organic compounds react in the presence of sunlight. Emissions from vehicles, power plants, and industrial facilities are major contributors.
- Reducing ozone levels through regulations and policies that limit emissions can lead to significant improvements in air quality and public health outcomes.
