The poor air quality of Canadian forest fires remains a concern on Tuesday during much of the regions of the upper and northeast medium.
Millions of people in at least 10 states from northern Minnesota to New Hampshire woke up with nebulous skies while hundreds of forest fires in Canada pushed smoke across the border.
The National Meteorological Service of Detroit, Michigan, said a warning of air quality is in force until Tuesday night.
Meanwhile, the National Meteorological Service for Twin Cities, Minnesota, said that the persistent forest fire smoke will move from the early afternoon area, giving way to a “pleasant summer day.”
The Air Quality Index on Tuesday throughout the west and the Northeast varied from “moderate” to “unhealthy” for sensitive adults. Some areas in northern Wisconsin, East of Pennsylvania, northern Vermont and Michigan parts had a “unhealthy” air quality index.
The smoke of the forest fire is a concern because it contains small particles that have less than 2.5 micrometers in diameter, which can reach the inside of the lungs, exacerbating or increasing the risk of chronic pulmonary diseases, asthma and lung cancer.
748 active fires were burning in Canada until Tuesday morning, including 199 classified as “out of control”, according to the Canadian Integential Forest Firefighters Center.
