Air Quality

In Riverside, pollutants (often called smog, May Gray or June Gloom) and pollen can cause bad air quality. Some people experience respiratory health problems caused by bad air quality. Sunlight and lack of wind can trap pollutants in an area, causing health effects to worsen. The Environmental Protection Agency monitors air quality every day across the country. If air quality is harmful here, the South Coast Air Quality Management District will issue advisories.

Pay attention to signs of health problems

  • Wheezing, coughing & trouble breathing
  • Red, itchy & burning eyes, nose & mouth
  • Pain during deep breathing
  • If you have any of these symptoms, talk to your doctor or nurse.


Help Reduce Pollution and Bad Air Quality

There are things you can do to reduce the formation of ground-level ozone, the main chemical in smog.

Take precautions with your vehicle

  • Drive less often.
  • Refuel your vehicle after 6pm. Sunlight reacts with pollutants in the air to produce smog.
  • Ensure your gas cap is on tight.

Limit use of products with reactive fumes

  • Limit use of oil-based paint, varnishes, and solvents that produce fumes.
  • Use an electric starter instead of starter fluid for your grill.
  • Use gas-powered lawn and power equipment after 6pm.

Conserve energy

  • Conserve energy in your home. 
  • Turn off lights.
  • Moderate use of heat and air conditioning.
