by Thousands of residents across California and Oregon have been advised to remain indoors as air quality in parts of the states reaches the “unhealthy” range, according to the Environmental Protection Agency (EPA). The warnings come amid heightened concerns over air pollution and its health effects, particularly for vulnerable populations.
Air Quality Concerns
The EPA’s AirNow map shows that areas around La Pine, Oregon, and Portola, California, are experiencing unhealthy air quality as of Tuesday morning. Officials are urging residents to limit outdoor activities, especially those in sensitive groups such as:
- Children
- Older adults
- Individuals with respiratory conditions or heart disease
When air quality reaches the “unhealthy” category, the EPA advises that sensitive groups avoid prolonged or intense outdoor activities and, when possible, move activities indoors. Other members of the public are encouraged to reduce strenuous outdoor work and take frequent breaks to minimize exposure.
Understanding the Air Quality Index (AQI)
The U.S. Air Quality Index (AQI), developed by the EPA, provides a standardized system for reporting air pollution levels. The AQI uses a scale from 0 to 500 with color-coded categories indicating severity:
- 0–50 (Green): Good — Air quality is satisfactory; little or no health risk.
- 51–100 (Yellow): Moderate — Acceptable air quality, but sensitive individuals may experience minor effects.
- 101–150 (Orange): Unhealthy for Sensitive Groups — Health effects possible for sensitive populations; general public less affected.
- 151–200 (Red): Unhealthy — Everyone may experience health effects; sensitive groups may experience more serious impacts.
- 201–300 (Purple): Very Unhealthy — Health alert; everyone’s risk of adverse effects increases.
- 301+ (Maroon): Hazardous — Emergency conditions; everyone is likely to be affected.
AirNow warns that even healthy individuals may experience temporary symptoms from elevated particle pollution, including eye, nose, and throat irritation, coughing, phlegm, chest tightness, and shortness of breath.
Health Risks of Particle Pollution
Scientific studies have linked exposure to particle pollution with a variety of serious health effects, including:
- Premature death in people with heart or lung disease
- Nonfatal heart attacks
- Irregular heartbeat
- Aggravated asthma and decreased lung function
- Increased respiratory symptoms such as coughing or difficulty breathing
Populations most at risk include children, older adults, people with heart or lung disease, and communities with low socioeconomic status or minority populations, as these groups may be either more sensitive or more heavily exposed to particle pollution.
What Residents Should Do
Authorities advise residents in affected areas to:
- Monitor local air quality maps regularly
- Avoid strenuous outdoor activities
- Take extra precautions if sensitive or vulnerable
- Move activities indoors whenever possible
Maintaining awareness of AQI updates and following these health safety recommendations is crucial to minimizing exposure and preventing health complications.
