King County earns mixed grades for air quality
May 15, 2012
King County earned a D grade for smog pollution in the latest air quality report from the American Lung Association, officials at the nonprofit association announced April 25.
The report found smog levels in Washington remained at similar levels as in previous years. King County received the grade for ozone, or smog, the most widespread air pollution.
When inhaled, ozone irritates the lungs, like a bad sunburn. The irritant can cause wheezing, coughing, asthma attacks and premature death.
However, for particle pollution, King County earned an A ranking from the American Lung Association. In Washington, particle pollution levels can spike dangerously for hours to days during the winter home heating season.
