U.S. Cities Have the Worst Air Quality in the World
How to stay safe from wildfire smoke
1Air Pollution Crisis
Wildfires in Canada are sending dense smoke to the Midwest and Atlantic coast of the U.S. Cities like Chicago, Detroit, and Washington, D.C., rank among the worst in air quality globally.
2Health Impacts
Wildfire smoke may be 10 times more dangerous than other air pollutants. A 2021 study linked this smoke to increased respiratory illnesses.
3Death Rates
Between 2006 and 2020, wildfire smoke caused over 24,000 deaths annually in the U.S. Research shows there is no safe exposure threshold.
4Ozone and Smog
Wildfire smoke reacts with sunlight and urban pollutants to produce ozone, which contributes to smog formation and increases mortality rates.
5Mental Health Effects
Wildfire smoke can elevate stress and depression rates. Children are particularly vulnerable to its adverse effects.
6Protection Measures
The EPA recommends keeping doors and windows closed and using air filters indoors. Wearing N95 masks and avoiding outdoor exercise are also crucial precautions.
