Statewide, OR—The Oregon Department of Environmental Quality and the Lane Regional Protection Agency are issuing an air stagnation advisory for all of the Willamette Valley and east through The Dalles, Central Oregon, John Day and Northern Harney County until Wednesday afternoon, and in Southern Oregon from the Coast through Klamath and Lake Counties through Thursday morning.
Forecasters expect air quality to deteriorate due to an extended period of stagnant air. During such conditions, smoke can be trapped at ground level where people breathe.
Multnomah County is issuing a voluntary wood burning curtailment beginning at noon today. Visit multco.us/woodsmokestatus for more information.
DEQ asks people in the affected areas to refrain from outdoor burning and to use alternatives to woodstoves if other heating options are available and practical. Information on woodstoves and woodstove smoke: http://www.oregon.gov/deq/Residential/Pages/Woodst...
DEQ also asks people in the affected areas to limit the use of fireworks which can have a detrimental effect on air quality.
Numerous scientific studies have linked smoke pollution to a variety of problems including coughing, aggravated asthma, bronchitis and irregular heartbeat. Pollution levels tend to be highest during evening and morning hours.
