Smoke from Canadian wildfires continues to affect air quality

Posted: Updated:

Smoke from wildfires in parts of western Canada continues to affect the air quality in eastern Iowa.

The Iowa Department of Natural Resources said the smoke, originating from wildfires hundreds of miles away and carried along the jetstream, caused a spike in fine particulate levels that are expected to last until the wind blows them out.

The Environmental Protection Agency's threshold for particulate is 35 micrograms per cubic meter.

As of 10 p.m. Tuesday morning, Cedar Rapids was at 43 micrograms, Iowa City was at 70 micrograms and Clinton was at 89 micrograms, according to the DNR.

Most of eastern Iowa was at 36 micrograms or above, according to the DNR.

The agency recommends those with respiratory or heart diseases, the elderly and children limit prolonged outdoor exertion until air quality improves.
