US Air Quality Alerts: Toxic Smog Hits Millions
21 Jan
Summary
- Unhealthy air quality affects millions in California and Oregon.
- Microscopic PM2.5 particles pose serious health risks.
- Residents urged to limit outdoor activity due to toxic smog.

Dangerous air quality levels, classified as 'unhealthy,' are currently affecting millions of Americans on both the East and West Coasts. In California and Oregon, microscopic PM2.5 particles, which can penetrate deep into the lungs, have reached hazardous concentrations.
Cities like Los Angeles have seen air quality reach levels posing risks to all residents, while large areas of Oregon are also experiencing significantly elevated PM2.5. Health experts caution that prolonged exposure can lead to respiratory problems and aggravate existing conditions.
Authorities are urging people to reduce outdoor activity and follow air quality forecasts. Stagnant air conditions are identified as a major factor, trapping pollutants near the ground and worsening air quality, particularly in regions like southern Oregon and western Idaho.
