(Portland, OR)  --  The air from Vancouver to Eugene will be extra smoggy this week.  An Air Quality Advisory has been issued for elevated levels of ozone pollution.  It could be unhealthy for sensitive groups like children, people over 65, pregnant women and people with heart disease or respiratory conditions.  You can help reduce smog by limiting driving, refuel vehicles when it's cooler, don't use gas powered engines, and postpone painting and aerosol spray projects.
