Air Quality Alert


ORC001-025-045-212115-
Baker-Harney-Malheur-
242 PM MDT Mon Aug 20 2018 /142 PM PDT Mon Aug 20 2018/

...AIR QUALITY ADVISORY FROM THE OREGON DEPARTMENT OF ENVIRONMENTAL
QUALITY FOR EASTERN OREGON...

The Oregon Department of Environmental Quality has issued an Air
Quality Advisory for Baker, Malheur, and Harney Counties due to
elevated pollutant levels. This Advisory will remain in effect until
air quality conditions have significantly improved.

Inversion conditions are expected over the area, with light winds
and limited mixing of the air.  During these conditions, smoke can
be trapped at ground level and potentially build up in concentration
for the duration of the stagnant air pattern.

DEQ asks people in the affected areas to refrain from outdoor
burning and to use alternatives to wood stoves if other heating
options are available and practical.  Information on wood stoves,
and wood stove smoke, can be found at:
http://www.oregon.gov/deq/Residential/Pages/Woodstoves-Health.aspx.
Be sure to check for any local burning restrictions or wood stove
advisories in each particular community before burning.

Exposure to ambient particulate matter pollution is one of the top
risk factors that contribute to premature death in the United
States, accounting for approximately 100,000 deaths annually.
Numerous scientific studies have linked smoke pollution to a variety
of problems including coughing, aggravated asthma, bronchitis, and
irregular heartbeat.

Health officials recommend that young children, pregnant women,
asthma suffers, those with lung or heart conditions, and adults age
65 and older limit vigorous outdoor activity.  Pollution levels tend
to be highest during morning and evening hours.

Visit the Oregon DEQ internet site at
http://www.deq.state.or.us/aqi/ for current conditions.

...AIR QUALITY ALERT IN EFFECT UNTIL FURTHER NOTICE...

Oregon Department of Environmental Quality has issued an Air
Pollution Advisory...in effect until further notice.

Wildfires burning in the region combined with forecast conditions
will cause air quality levels to fluctuate and could be at unhealthy
levels. While there will be periods of improvements, they will be
temporary.

Pollutants in smoke can cause burning eyes...runny nose...aggravate
heart and lung diseases...and aggravate other serious health
problems. Limit outdoor activities and keep children indoors if it
is smoky. Please follow medical advice if you have a heart or lung
condition.
