Air Pollution Chart
After reviewing Ch. 8 and 9 of your text, complete the following table, then respond to the questions that follow:
Issue | Sources | Health/Environmental Effects |
Carbon dioxide (CO2) | Primary (mobile and stationary) | Makes difficult for blood to carry oxygen. Low levels- headache and fatigue. High levels- mental impairment. |
Chlorofluorocarbons (CFCs) | Primary (mobile and stationary) | Varies from no effect to breathing problems, to cancer.Breaks down stratospheric ozone into molecular oxygen. Allows increased amount of solar UV to reach Earth surface. All contribute to smog except Methane, which links to global warming. |
Ground-level ozone (O3) | Secondary | Like previous, aggravates any breathing problems. Can also destroy crops. |
Sulfuric acid (H2SO4) | Secondary | Also aggravates breathing problems. Can burn crops, metal, plastic, concrete, and stone. |
Note: Some pollutants may not have direct health effects.
Choose one of the following atmospheric issues: air pollution, global warming, ozone depletion, and acid deposition. Then, respond to the following:
* What air pollutants combine and contribute to this issue? All compounds contribute to global warming, but CO2 is biggest contributor and has the severest effects.
* Briefly describe the health and environmental problems caused by the selected atmospheric issue. Health implications vary from none to breathing problems, to cancer. Environmental problems vary from ozone depletion, to crop failure, to aggravation of an already severe issue.
* Provide one key solution to help either reduce the effects or recover from the effects of the selected issue. I think the best way to mitigate global warming is to improve the energy efficiency of the vehicles we use across the world. I think this would have the greatest affect in reducing the problem.
