: These are emitted directly from an identifiable source. Examples include Carbon Monoxide (CO) from vehicle exhaust, Sulfur Dioxide ( SO2cap S cap O sub 2

) react with Volatile Organic Compounds (VOCs) in the presence of heat and UV radiation. 2. Major Sources of Pollution

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:

: 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 : These are emitted directly from an identifiable source

: Internal combustion engines in cars, trucks, and airplanes are responsible for up to 80% of urban pollution, emitting COcap C cap O NOxcap N cap O sub x PMcap P cap M

: Large-scale industrial facilities, power plants, and refineries release significant amounts of SO2cap S cap O sub 2 and heavy metals like lead. Major Sources of Pollution Air Quality Control: Formation,
