| 148345347 | Industrial smog | Smog from industrial pollution and fossil fuel combustion. Steps: 1. C + O2 = CO2 or CO 2. S + O2 = SO2 3. SO2 + O2 = SO3 4. SO3 + H2O = H2SO4 5. H2SO4 + NH3 = (NH4)2SO4 | |
| 148345348 | Photochemical smog | Smog that is catalyzed by UV radiation and tends to be nitrogen-based. NO + VOCs + O2 + uv = O3 + PANs | |
| 148345349 | Nitrogen Dioxide (NO2) | Formed from burning of fossil fuels. Forms nitric acid (HNO3) in the air and contributes to acid rain and cultural eutrophication. | |
| 148345350 | Ozone (O3) | Formed from sunlight reacting with NOx and VOCs in the air. A major component of photochemical smog. | |
| 148348852 | Peroxyacyl Nitrates (PAN) | Hydrocarbons, oxygen, and nitrogen dioxide combined by ultraviolet radiation. (hydrocarbons + O2 + NO2 + light = CH3COOONO2 (PAN)) They transport unstable compounds such as radicals and NO2 away from urban and industrial areas. | |
| 148348853 | Sulfur Dioxide (SO2) | Formed from burning of high-sulfur fossil fuel, smelting of metals, and paper manufacturing. Contributes to acid rain. Clean Air Act helped the level of this pollutant decrease significantly in US. | |
| 148348854 | Suspended Particulate Matter (PM10) | Include smoke, dust, diesel soot, lead, and asbestos. Main cause of health problems. Cause lung irritation and damage. | |
| 148348855 | Volatile Organic Compounds (VOCs) | Over 600 types of organic compounds that have a high vapor pressure. Found in paints, aerosol sprays, dry-cleaning fluids, and industrial solvents. Cause respiratory irritation and damage. |
