Particulate matter, often referred to as particle pollution, consists of a complex mixture of microscopic solid particles and liquid droplets suspended in the air. These pollutants originate from direct emissions such as construction sites and fires, or they form in the atmosphere through chemical reactions involving pollutants from industrial facilities and vehicles. Categorized primarily by size into PM10 and PM2.5, these microscopic substances pose severe health risks by penetrating deep into human lungs and the bloodstream. Furthermore, fine particles are a primary contributor to environmental haze, significantly reducing visibility across many natural landscapes. To mitigate these hazards, regulatory agencies enforce strict standards on emissions while offering Air Quality Index tools to help individuals monitor exposure and protect public health.
