Particulates, often referred to as particulate matter (PM), are tiny solid or liquid particles suspended in the air. They can vary in size, composition, and origin. Particulates are classified based on their diameter, with the most commonly referenced categories being: 1. **PM10**: Particulate matter with a diameter of 10 micrometers or smaller. These particles can be inhaled and may reach the lungs. 2. **PM2.
