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 Natural Sources : These include volcanic eruptions (

: Dispersed activities such as agricultural fertilizer use (releasing ammonia) and the use of household products (VOCs). Natural Sources : These include volcanic eruptions ( SO2cap S cap O sub 2 and ash), wildfires (smoke and PMcap P cap M ), and biological decay ( CH4cap C cap H sub 4 3. Dispersion Factors

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