Canada Wildfires Smoke Returns to Pollute U.S. Air
Air polluted by the Canadian wildfires is back in the United States this week.
There are nearly 900 wildfires burning across Canada, but the smoke this week will be coming from the western part of the country.
“Unfortunately, the wildfire smoke will begin to make a return to the region to start the new week,” according to the National Weather Service in the Philadelphia area.
Air quality alerts were issued for multiple areas, including the Midwest, the Great Lakes, central Tennessee and North Carolina, as well as the Northeast.
By 5 a.m. Eastern time on Monday, several cities were reporting elevated readings of the Air Quality Index: 158 in Buffalo, 155 in Chicago and 142 in Nashville. The index runs from 0 to 500; the higher the number, the greater the level of air pollution. An A.Q.I. of 201 or more is considered very unhealthy.
