Portland, OR—The Oregon Department of Environmental Quality and the Southwest Washington Clean Air Agency issued an air quality advisory Monday for the Portland-Vancouver metro area due to elevated levels of ozone pollution, or smog.
Información en español
The agencies expect ozone pollution to reach levels Monday afternoon that could be unhealthy for sensitive groups, including children, seniors, pregnant women and people with heart disease or respiratory conditions. Health officials recommend sensitive groups limit outdoor activity when pollution levels are high.
DEQ urges residents to protect their health and limit activities that cause pollution during this advisory. Recommendations include:
• Limit driving by using public transit, carpooling or other alternative transportation.
• Avoid unnecessary engine idling.
• Refuel vehicles during cooler evening hours.
• Postpone mowing the lawn.
• Postpone painting and aerosol spray projects.
Smog irritates the eyes, nose and lungs, and contributes to breathing problems. Consult your health care provider if these symptoms worsen.
DEQ expects the air quality advisory to last until Tuesday morning. Smog levels should improve overnight and through the rest of the week.

Ozone forms when hot temperatures and low winds combine with pollution from cars, gas-powered engines and chemicals in paints and aerosols. These air pollutants react with sunlight and heat to produce ozone and haze.
Ozone pollution increases throughout the day with exposure to sunlight, so pollution levels tend to be highest during afternoons and early evenings. Air quality monitors may show good air quality in the morning, then quickly jump to unhealthy levels later in the day.
DEQ’s color-coded Air Quality Index provides current air quality conditions and ranks air quality as follows: Green is good. Yellow is moderate. Orange is unhealthy for sensitive groups such as children, the elderly, pregnant women and those with respiratory conditions. Red is unhealthy for everyone. Purple is very unhealthy for all groups. Maroon is hazardous.
