APM-2.5 (Airborne Particulate Matter)

APM-2.5, or Airborne Particulate Matter with a diameter of 2.5 micrometers or smaller, refers to tiny particles suspended in the air that can be inhaled deeply into the lungs. These particles originate from various sources, including vehicle emissions, industrial processes, and natural events like wildfires. Due to their small size, APM-2.5 can pose serious health risks, leading to respiratory issues and cardiovascular diseases. Monitoring and reducing APM-2.5 levels is crucial for improving air quality and protecting public health.
