Sources are generally divided into human-made (anthropogenic) and natural categories: :

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 Air Quality Control: Formation and Sources, Dis...

Air pollutants are categorized by how they enter the atmosphere: where they originate

: 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 and Sources, Dis...

Dispersion refers to how pollutants spread and dilute in the atmosphere. It is determined by several critical environmental factors: Air Pollution and Your Health
