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) | Emissions from motor vehicles; burning fossil fuels; land clearing; forest combustion | (CO2) causes Greenhouse effect and global warmingEssential for internal respiration, but when levels are high CO2 can cause asphyxiation, frostbite, kidney damage and comas. |
Chlorofluorocarbons (CFCs) | Developed as a safe alternative to ammonia and sulfur dioxide refrigerants.   They are non-flammable, non-explosive, non-corrosive, very low toxicity.   Used in refrigeration of perishable foods, medical supplies, air conditioners, communication equipment, computers and navigation equipment for air crafts. | There are no known health or environmental effects with the use of CFCs. |
Ground-level ozone (O3) | Created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC) in the presence of sunlight.   Emissions from industrial facilities, electric utilities, motor vehicle exhaust, gasoline vapors, and chemical solvents are some of the major sources. | (O3) causes airway constriction, wheezing and breathing difficulties, coughing, inflammation like a sunburn, and aggravation of asthma, susceptibility to pneumonia and bronchitis, and lung damage.(O3) can interfere with the ability of sensitive plants that produce and store food, damaging leaves of the trees and plants, reducing forest growth and crop yields. |
Sulfuric acid (H2SO4) | Used in lead-based batteries for vehicles, ore processing, fertilizing manufacturing, oil refining, and waste water processing. | (H2SO4) can cause lung damage, coughing, shortness of breath, severe skin irritation and burns.   If swallowed it can cause nausea, vomiting, diarrhea and in severe cases, death.The use of (H2SO4) can...
