Question | Answer |
VOC | build up in office buildings |
Temperature Inversion | warm air keeps cool air at surface |
Light Pollution | decreased by pointing lights down |
Acidity of Soil | as acidity increases more nutrients washed out of the soil |
Clean Air Act | EPA can regulate emissions |
Sick Building Syndrome | more frequent in warm climates with air conditioning |
Ozone | ground level effects children and people with respiratory disease |
Noise Pollution | cause deafness at 120 db or more |
Fossil Fuels | release sulfur and nitrogen oxides |
Acid Rain | results from burning fossil fuels, precipitation is normally slightly acidic |
Primary Pollutants | released directly to atmosphere, examples: carbon monoxide, ozone |
Sulfur Dioxide | combination of oxygen, UV rays, and auto emissions |
Scrubbers | remove poisonous gases from smokestacks |
Indoor Air Quality | low in tightly sealed building with air conditioning, high in buildings with good ventilation |
Asbestos | $40 billion dollars for schools to remove |
pH | low=acidic, high=basic, 7 is neutral |
Aluminum | leaches through acidic soil |
Canada | pollution comes from Midwest and eastern US |
Air Pollution | from burning fossil fuels |
Particulate Matter | from agriculture and construction, forms clouds |
Carbon Monoxide | lowers the amount of oxygen blood can carry |
Automobiles | fumes escape when filling tanks, nitrogen oxides released with exhaust, largest producer of primary pollutants |
Secondary Pollutant | smog combines with sunlight, combination of primary pollutants |
Smog | decreased by ethanol, formed by sunlight, exhaust, and ozone |
