Air Pollution Advisories

An Air Pollution Advisory is a call-to-action that DEQ issues to encourage individuals and businesses to reduce pollution-producing activities during summer hot spells and winter air stagnation times.

During summer, DEQ issues Air Pollution Advisories for Smog (ozone) in the Portland, Salem and Medford areas when hot temperatures and low winds cause smog levels to rise.

• Why does the AQI usually indicate good air quality even during a smog advisory?

During winter, DEQ issues Air Pollution Advisories for Particle Pollution (PM_2.5) for any area of the state when cold temperatures and stagnant air cause particle pollution levels to rise.

Air Quality Index

The Air Quality Index (AQI) is a color-coded tool which shows air pollution levels. It is a scale used to report actual levels of ozone and other common pollutants in the air. The higher the AQI, the higher the health concern. The AQI is divided into categories that correspond to different levels of health concern.

• Frequently asked questions about the air quality index
• An audio recording of the information displayed in the AQI can be heard by calling 1-800-961-6313.
