chapter 9 (atmosphere) Flashcards
examples of primary pollutants
PM10, NO, NO2, SO2, CO2, C)
examples of secondary pollutants
SO3, H2SO4, O3, PANS
forms when fuels are burned at high temps, voicanos, lightning, bacterial action in soil
NO2
major component of photochemical smog
formed by sunlight reacting with NOx and VOCs in air
O3
formed from reaction of hydrocarbons with oxygen and nitrogen dioxide and being catalyzed by uv radiation
PANs
produced by burning of high sulfur oil or coal, smelting of metals, paper manufacturing
combines with water vapor in air to produce acid precipitation
SO2
smoke, dust, diesel soot, lead, asbestos
PM10s
organic compound with a high vapor pressure
VOCs
industrial smog
sulfur based
grey air smog
photochemical smog
catalyzed by uv radiation
nitrogen based
brown air smog
wet acid deposition
acid rain, fog and snow
dry acid deposition
acidic gases and particles
half acidity in atmosphere falls back to earth through dry deposition
acid shock
rapid melting of snow pack that contains dry acidic particles
urban heat islands
metropolitan areas that are significantly warmer than their surroundings
temperature inversions
when air temp increases with height above the ground
sick building syndrome
molds, bacteria, CO, radon, allergens, asbestos, tobacco smoke, formaldehyde, vocs
clean air act
protect public health from air pollution and limit effects of air pollution on the environment
kyoto protocol
would have required US to reduce greenhouse emissions by 7%
cost of meeting emission targets was too high and the time frame was too short for implementation
dominant form of noise pollution
transportation sources
sensory hearing loss
damage to inner ear
most common
