impact risk if chronic exposure
The air is moderately polluted. Greater than the maximum limit established for one year by WHO. A long-term exposure constitutes a health risk.
(CNN) The deadly wildfires are not only destroying homes and burning everything in their path -- but they're also causing poor air quality.
On Tuesday, a thick haze blanketed parts of the Northwest, including Seattle, as fires across the border in Canada burned. Things were looking a little better Wednesday, as cleaner air began pushing onshore, according to the National Weather Service in Seattle, which said the state had the worst air quality in the country.
Smoky haze obscures the Space Needle and downtown Seattle on August 14.
The smoke that is blanketing Washington, Oregon and California is smoke coming from the wildfires burning in British Columbia, according to the National Weather Service Seattle.
Air quality advisories were in effect for portions of Washington and Oregon, according to the weather service.
The air quality was considered unhealthy in western parts of Washington.
