Oregon DEQ Issues Air Pollution Stagnation Advisory For Much of Northeast and Central Oregon through Monday
Affected cities: Pendleton, Hermiston, The Dalles and the Columbia River Gorge; residents asked to voluntarily limit wood heating
The Oregon Department of Environmental Quality is issuing an air stagnation advisory for much of Northeast and North-Central Oregon due to stagnant air conditions and increasingly high levels of air pollution.
The advisory is for the Lower Columbia Basin, including Pendleton, Hermiston, the foothills of the Blue Mountains and the Columbia River Gorge east of The Dalles. The advisory is in effect through the afternoon on Monday, Nov. 25.
This advisory is based on the latest information from the National Weather Service, which on Thursday issued its own air stagnation advisory for the region. Due to a persistent temperature inversion and light winds, air quality in portions of the affected area is expected to deteriorate through the weekend.
At this time, the advisory does not include Bend, Portland, or anywhere else in the state.
DEQ asks people in the affected areas to halt open burning and limit use of uncertified woodstoves. Persons with questions about open burning should contact their local fire department. DEQ urges people who have alternative heating options not to burn in woodstoves or fireplaces. People should also limit driving and vehicle idling.
During periods of air stagnation, smoke is trapped at ground level where people breathe the smoke particles deep into their lungs. Numerous scientific studies have linked smoke pollution to a variety of problems including but not limited to coughing, aggravated asthma, bronchitis and irregular heartbeat.
Health officials recommend that young children, pregnant women, asthma sufferers, those with lung or heart conditions and adults age 65 and older limit vigorous outdoor activity. Pollution levels are highest during evening and morning hours due to woodstove use and inversion conditions. Individuals likely to be affected should check with their doctor should pollution make asthma or other medical conditions worse.
