What This Means

An AQI of 110 indicates that air quality is beginning to reach levels that may be unhealthy for specific populations.

The following groups are at increased risk when PM2.5 levels are in the Unhealthy for Sensitive Groups range:

• People with heart or lung disease
• Older adults
• Children
• People with diabetes

What You Should Do

Members of sensitive groups should consider reducing prolonged or heavy outdoor exertion. While it is generally safe to be active outdoors, it is recommended to take more breaks, choose less intense activities, and monitor for symptoms such as coughing or shortness of breath. The general public is not expected to be affected at this level.
