PM2.5 (Particulate Matter 2.5) refers to microscopic solid or liquid particles in the air that have a diameter of 2.5 micrometers or less—roughly 30 times smaller than the diameter of a human hair. Due to their minute size, PM2.5 is considered the most hazardous air pollutant. These particles can penetrate deep into the respiratory tract and lungs, and even enter the bloodstream, causing respiratory, cardiovascular, and other serious health issues. Key sources include vehicle emissions, power plants, and industrial combustion. The measurement and monitoring of PM2.5, expressed in µg/m3, is crucial for air quality management and serves as a critical public health indicator in urban and industrial environments.
