Respirable particles are tiny airborne particles that are small enough to be inhaled into the respiratory system. Typically, these particles are less than 10 micrometers in diameter (PM10), with a significant focus on those less than 2.5 micrometers (PM2.5) due to their ability to penetrate deep into the lungs and even enter the bloodstream. These particles can originate from various sources, including industrial processes, vehicle emissions, natural events like wildfires, and household activities.
