What term includes dust, smoke, and pollen particles that can be inhaled?

Explanation:
Particulate matter is the broad category for solid or liquid particles suspended in the air that can be inhaled. Dust, smoke, and pollen are classic examples of these inhalable particles. This umbrella term covers all such aerosols, with smaller fractions like PM10 and PM2.5 referring to specific size ranges within the same category (up to 10 micrometers and up to 2.5 micrometers, respectively). VOCs are volatile organic compounds that exist as gases or vapors, not particles, so they aren’t part of particulate matter. So the term that includes dust, smoke, and pollen particles that can be inhaled is particulate matter.
