The Illinois Environmental Protection Agency declared an “Air Pollution Action Day” for the greater Chicago area until midnight on Thursday.

Children, and those with pulmonary or respiratory diseases such as asthma, are recommended to limit their time outdoors.

The alert was in effect for northern and northeast Illinois and Northwest Indiana.

A tracker with the latest updates on air quality levels for areas across the state can be found on the AirNow government website.

Conditions at ground level are unhealthy in Midwest

The U.S. Environmental Protection Agency’s AirNow map indicated a vast area of “unhealthy” air quality stretching across eastern Minnesota into western Wisconsin and northern Iowa, marked in red. The Minneapolis-St. Paul metro region particularly experienced “very unhealthy” conditions displayed in purple, where Air Quality Index (AQI) values reached around 250, although there was a slight improvement by late morning.

The Air Quality Index (AQI) evaluates the cleanliness or pollution levels of the air, emphasizing the potential health effects one might experience a few hours or days after exposure. The AQI considers pollutants like ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide. The primary concern in this situation stems from particulate matter due to fires.

The AQI scale ranges from green, indicating satisfactory air quality with minimal health risk, to maroon, which signals hazardous conditions. At this level, there are health warnings of emergency situations where the likelihood of health effects is heightened for everyone, according to AirNow.

The Canadian fire situation

Canada is having another bad wildfire season, and more than 27,000 people in three provinces have been forced to evacuate. Most of the smoke reaching the American Midwest has been coming from fires northwest of the provincial capital of Winnipeg in Manitoba.

Winnipeg hotels opened Monday to evacuees. More than 17,000 Manitoba residents have been displaced since last week, including 5,000 residents of the community of Flin Flon, nearly 400 miles (645 kilometers) northwest of Winnipeg. In neighboring Saskatchewan, 2,500 residents of the town of La Ronge were ordered to flee Monday, on top of more than 8,000 in the province who had been evacuated earlier.

In Saskatoon, where the premiers of Canada’s provinces and the country’s prime minister met Monday, Saskatchewan Premier Scott Moe said all of Canada has come together to help the Prairie provinces.

Two people were killed by a wildfire in mid-May in Lac du Bonnet, northeast of Winnipeg.

Canada’s worst-ever wildfire season was in 2023. It choked much of North America with dangerous smoke for months.
