As smoke from Canada's wildfires approaches the Midwest, Chicago's air quality is among the worst in the world.

By

 Weeks after wildfire smoke from Canadian flames covered most of the East Coast with hazy, orange sky and dangerous air quality, Chicagoans awoke Tuesday to the world's worst air quality.

Thick smoke covered the skies over Chicago early Tuesday morning, reducing sight, and a slight burning odour permeated the air as residents commuted to work. According to the tracker AirNow.gov, unhealthy levels of pollution from the smoke extended throughout areas of the Great Lakes Region around Chicago, including most of Wisconsin and parts of Michigan, Illinois, Indiana, and Ohio.


That implies that anyone in a vulnerable category, such as small children, elderly individuals, or those with heart or lung illness, should avoid any physical exercise, and everyone else should minimise their time spent outside.

Where is the air quality bad on Tuesday?

Major cities in the Midwest had air deemed unhealthy or unhealthy for sensitive groups Tuesday morning, including Chicago, Milwaukee, Indianapolis, Cincinnati, Detroit and Minneapolis.

    • Three U.S. cities ranked in the top 10 cities with the worst air quality in the world Tuesday morning, according to IQAir: Chicago, Minneapolis and Detroit. Other cities in the top 10 were Dubai; Jakarta, Indonesia; and Delhi, India.
    • Wisconsin's Department of Natural Resources issued an advisory for much of the state that's expected to last through Thursday afternoon, with air quality expected to be most severe on Tuesday and Wednesday. The sky in Milwaukee was hazy and smelled like smoke starting Monday.
    • Tuesday was declared a statewide day of action by the Michigan Department of Environment, Great Lakes and Energy because of unhealthy and hazardous air quality.
    • On Sunday and Monday, a smoky haze had settled over parts of northwestern Vermont and was carried out Monday afternoon by southerly winds.

Why is the air quality so bad in Chicago?

The number of particles in the air from Canadian wildfires that have migrated into the United States at various times over the previous several weeks has made air quality poor. Wind patterns, according to Zachary Yack, a meteorologist with the National Weather Service in Chicago, are mostly dictating where the smoky air moves.



On Tuesday, Chicago and Milwaukee experienced the most severe air pollution globally as smoke from wildfires in Quebec, Canada, infiltrated the Midwest. These fires have been affecting parts of the United States since earlier this month, and both cities are currently categorized as "purple" on the Air Quality Index (AQI), indicating very unhealthy conditions.

According to AirNow, a government website monitoring air quality, at one point on Tuesday, Chicago's AQI reached 228, entering the purple zone, while nearby Milwaukee recorded a level of 221. Maps illustrating the present air quality in the United States indicate that Illinois, Wisconsin, and certain regions in neighboring states such as Minnesota, Iowa, Indiana, and Michigan are classified as "red" or unhealthy. This implies that some individuals may experience health problems due to the poor air quality.

The East Coast of the United States, previously affected by hazardous air quality from the Canadian wildfires earlier this month, now appears to be mostly clear. However, certain areas are in the "yellow" or moderate zone, indicating acceptable air quality but with potential risks for certain individuals.

According to #IQ #Air, an organization monitoring the global air quality index, major cities in the Midwest like Chicago, Milwaukee, and Detroit have the world's poorest air quality. Other cities on the list include Dubai, as well as Lahore and Karachi in Pakistan.

At the last of the wildfires, many cities have issued air quality alerts this month, urging people, particularly those with sensitivities, to avoid spending time outdoors. On June 7, New York City was enveloped in an orange haze as wildfire smoke spread across the country, ranking it second globally for the worst air quality after Delhi, India. However, Detroit soon surpassed New York in the rankings.

The Weather Channel depicted a hazy sky in #Chicago on Tuesday, prompting the #National #Weather #Service #Chicago to declare June 27 and 28 as air quality action days, advising people in Chicago and Indianapolis to minimize their time outdoors.
