BISMARCK — North Dakota's Department of Environmental Quality is advising residents to limit outdoor activities in the midst of smoky conditions, especially if they have a respiratory condition or if they're elderly or a child.

Ash and soot from northern Canada wildfires have been increasing in eastern North Dakota. Local agriculture-related burning could be adding to the issue.

Prolonged outdoor exposure is to be avoided, and people who experience breathing problems due to the smoke should seek immediate medical attention, officials cautioned.

Eastern North Dakota is experiencing most of the smoke impact, but the department also is monitoring conditions in the west.
