Air Pollution Chart

After reviewing Ch. 8 and 9 of your text, complete the following table, and then respond to the questions that follow:

Issue
Sources
Health/Environmental Effects
Carbon dioxide (CO2)
Combustion of fossil fuels such as coal, oil, gas in power plants, automobiles and industrial facilities. Reduces bloods ability to transport oxygen; headaches and fatigue, mental impairment or death at high levels. Chlorofluorocarbons (CFCs)

Human made organic compounds containing chlorine and fluorine Attack the stratospheric ozone layer which may cause excessive exposures to UV radiation. This may increase cataracts and weaken the immune system and cause skin cancer. It may also disrupt the eco system. Ground-level ozone (O3)

Formed in the atmosphere
Irritates eyes, produces chest discomfort, and aggravates asthma. Damages crops, trees and other vegetation. Sulfuric acid (H2SO4)
Electric power plants
Irritate respiratory tract; same effects as particulates
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?

Briefly describe the health and environmental problems caused by the selected atmospheric issue. Provide one key solution to help either reduce the effects or recover from the effects of the selected issue.

The atmospheric issue that I chose was global warming. The air pollutants that combine and contribute to this issue are Chlorofluorocarbons, carbon dioxide, and nitrous oxide. They accumulate in the air as a result of human activity. The effects of global warming can affect our wildlife. If we continue to have severe weather, we will have more heat related deaths. The dirty air could cause more cases of asthma and allergies. Some things that can be done to fight global...
