Chicago currently has the worst air quality in the world due to smoke from Canadian wildfires, prompting officials to urge residents to be cautious. Data from IQAir.com shows that Chicago currently has an air quality index (AQI) of 193, which is considered to be unhealthy for residents. Following behind Chicago is Detroit, Michigan, and New Delhi, India. The worsening air quality in Chicago comes amid ongoing wildfires in Canada that previously resulted in a decline in air quality in some other East Coast cities such as New York City and New Jersey.
