The air quality in the Chicago area is expected to worsen through Friday night, as ozone pollution and fireworks-related smoke combine to create “Unhealthy for Sensitive Groups” conditions. This pollution could make breathing harder, particularly for those with respiratory issues.
The Illinois Environmental Protection Agency and the National Weather Service have issued an Air Pollution Action Day for much of northeastern Illinois, including Cook, Lake, DuPage, Kane, Will, and Kendall counties.
Air Quality Concerns in Chicago Area
The primary pollutant causing the decrease in air quality is ozone, which tends to accumulate during stagnant summer weather. Additionally, the smoke from fireworks is expected to increase fine particle pollution (PM2.5) in the evening hours.
This combined pollution could make the air harder to breathe for sensitive groups, including individuals with asthma, respiratory conditions, and children.
Cities like Chicago, Joliet, Aurora, Naperville, and Waukegan are under this air quality alert, and local residents are being urged to limit outdoor activity, especially during the afternoon and early evening when pollution levels are highest.
Health Precautions for Vulnerable Residents
Residents who are particularly vulnerable—such as those with asthma, elderly individuals, and children—should avoid prolonged outdoor activity during peak hours. It’s also recommended to stay indoors as much as possible, particularly during the times when pollution levels are at their worst.
Practical Steps to Reduce Emissions
In addition to avoiding outdoor activities, local authorities are asking all residents to help reduce pollution by following a few simple actions:
Avoid unnecessary driving to reduce vehicle emissions.
Refuel vehicles after dusk when air pollution levels are lower.
Use electric lawn equipment instead of gas-powered tools to prevent additional emissions.
Impact of July 4th Festivities
The timing of this alert coincides with the busy summer travel period and Fourth of July celebrations, which may worsen air quality further due to the additional use of fireworks. With an increase in outdoor activities and celebrations, it’s essential for residents to stay informed about air quality and take steps to protect their health.
Continued Monitoring and Updates
This Air Pollution Action Day alert is in effect through Friday night. As air quality conditions may worsen into the weekend, the Illinois Environmental Protection Agency and National Weather Service will continue to monitor the situation and provide updates as necessary.
It’s important for residents to stay aware of ongoing air quality reports to ensure they can take necessary precautions.
