Air Quality Control: Formation, Sources, and Dispersion Air quality control is a critical multifaceted approach to managing the hazardous substances—including solid particles, liquid droplets, and gases—that contaminate our atmosphere. Effective control requires understanding how these pollutants form, where they originate, and how they disperse across geographic boundaries. 1. Formation and Classification

: These form in the atmosphere through chemical reactions between primary pollutants and other atmospheric components, often catalyzed by sunlight. A prominent example is Ground-level Ozone ( O3cap O sub 3 ) , or smog, which forms when nitrogen oxides ( NOxcap N cap O sub x Air Quality Control: Formation, Sources, and Dispersion Air
Dispersion refers to how pollutants spread and dilute in the atmosphere. It is determined by several critical environmental factors: Air Pollution and Your Health Formation and Classification ) from power plants, and
