Dangers of wildfire smoke:

“There are many pollutants of concern in wildfire smoke,” including ozone, carbon monoxide and other toxic gases, says Hendrickson. Small particles in the smoke, called particulate matter 2.5 or PM2.5 — and even smaller ultra-fine particles known as PM0.1 — also pose a threat in large part because they can penetrate deep into the lungs, “enter the bloodstream, and reach every organ of the body.”
