First Air Pollution Action Day of 2018 Called

CHICAGO – Respiratory Health Association is alerting the public that the Illinois Environmental Protection Agency issued an Air Pollution Action Day alert to individuals in the Chicago Metropolitan area for Saturday. As a result of the high temperatures and low wind speeds, air pollution levels, specifically ground-level ozone, are expected to reach the “unhealthy for sensitive groups” category. This is the first Action Day issued for 2018. Due to weather conditions, ozone smog levels may remain high for several days over the holiday weekend.

An Air Pollution Action Day is declared when weather conditions are such that widespread ozone or fine particulate matter (PM2.5) levels are expected to be at or above the “unhealthy for sensitive groups” category on the U.S. EPA’s Air Quality Index for multiple days. Saturday, May 26th is expected to meet these criteria, therefore, an Air Pollution Action Day is being declared. At increased levels, ground-level ozone poses a potential health hazard to sensitive populations, especially individuals with respiratory or pulmonary conditions as well as active children and adults. Those individuals should take special precautions and follow their physician prescribed regimen. Residents should keep cool and limit physical activity when air pollution levels are high.

Employers and residents of the Chicago metropolitan area are asked to follow “Green Actions” (as described below) to reduce contributions to air pollution. These groups are also encouraged to share air quality forecasts and Action Day alerts with colleagues, friends and family to help protect their health.

  • Take public transit, Rideshare, walk or bike.
  • If driving, avoid idling, consolidate errands and run them after 7 p.m. when sunlight is not as strong.
  • Avoid using gasoline-powered equipment on Air Pollution Action Days.
  • Switch to energy efficient light bulbs.
  • Set your thermostat up 2 degrees.
  • Turn off and unplug electronics not in use.
  • Use environmentally-friendly household and cleaning products.
  • Use a charcoal chimney or gas grill instead of lighter fluid when grilling.
  • Do not burn leaves and other yard waste.
  • Sign-up to receive air quality forecasts via email at!
