Main Pollutants
There are six criteria pollutants for which the U.S. Environmental Protection Agency has set national ambient air quality standards:
- Carbon monoxide
- Ground-level ozone
- Lead
- Nitrogen dioxide
- Particulate matter
- Sulfur dioxide
- Smog Levels
Shreveport's air quality is in attainment with all of these standards. Ground-level ozone (also known as smog) is a concern throughout the country during the hottest months of the year. There are 2 monitors which measure and record ground-level ozone in the Shreveport area:
- One is located in Dixie, Louisiana, north of town
- The other is located at Shreveport Downtown Airport
The monitors are maintained by the Louisiana Department of Environmental Quality.
