particulate matter

Suspended atmospheric debris

Particulate matter refers to tiny solid particles or liquid droplets suspended in the air, ranging from visible dust and soot to microscopic pollutants.

In environmental and health contexts, it's often categorized by size: PM10 includes particles under 10 micrometers, while PM2.5 designates finer particles under 2.5 micrometers that can penetrate deep into the lungs.

Air quality alerts warned of elevated particulate matter from the wildfires.

High levels of particulate matter are linked to respiratory and cardiovascular problems.
