| Question | Answer |
|---|---|
| Carbon Monoxide | vehicle exhaust, burning of forests and grasslands |
| Carbon Dioxide | 93% in atmosphere is natural. The other from burning fossil fuels, clearing forests and grasslands. |
| Nitric Oxides | NO forms when nitrogen and oxygen react at high temps in auto engines and coal-burining plants. in air reacts w/O to make NO2. Both a part of photochemical smog. NO2 reacts w/ water vapor-acid rain |
| Nitrous oxide | N2O is a greenhous gas emitted from fertilizers, animal waste and burning of fossil fuels. |
| Sulfer dioxide | from combustion of sulfur-containing coal, oil refining and smelting of sulfer ore. big component of Asian Brown Cloud. |
| Sulfuric Acid | H2SO4-sulfur combing with water vapor =acid deposition. Damage crops, trees, soils, aquatic life. can aggrvate breathing problems. |
| Particulates | suspended solids from coal burining, vehicles, construction, plowed fields, ect.small particles very dangerous to health, cause irratation to nose,throatand lungs, asthma and can shorten life |
| Ozone | major component of photochemical smog mostly from vehicle exhaust. Causes breathing problems,irritates nose and throat, aggravates heart and lung disease. |
| Volatile Organic Compounds VOC's | hydrocarbons from rice paddies, landfills, oil and natural gas wells, cows, solvents and products we purchase.ex)methane, benzene, trichloroehtane |
| Components of Industrial Smog | Sulfur and carbon in coal and oil react w/oxygen to form SO2, CO and CO2. Sulfur dioxide reacts w/water vapor making sulfuric acid and ammonium sulfate which contribute to acid rain |
| Components of Photochemical Smog | vehicle exhaust reacts No and VOC's in city. Reacts with oxygen to make NO2, reacts w/sunlight and VOC's and resulting smog is a mixture of ozone, nitric acid and other compds. Sunny, dry climates have this worse. |
| Temperature Inversions | Layer of warm air stops a layer of cool air from rising, allowing ground-level pollutants to accumualte instead of disperse. Happens most in valleys between mtns-Donora, PA and cities surrounded by mtns on 3 sides, ocean on other -L.A. |
| Reverse effects in water and soils by... | add lime to water and soil to neutralize effects. Add phopshate fertilizer to acidified lakes. |
