APES Pollution: Air Pollution
Cards in this deck (25)
- 1Criteria Air Pollutantscarbon monoxide, lead, ozone, nitrogen dioxide, particulate matter, and sulfur dioxide.
- 2Carbon Monoxidecolorless, odorless gas
created from particle oxidation of carbon compounds
present in volcanic activity, fires, burning of fossil fuels, car emissions - 3Non-Point Source Pollutionwhen contaminant comes from a source that is not easily identifiable or from a number of sources
- 4Nitrous OxideN2O
major greenhouse gas, levels rising
Agricultural croplands are 70%
produced naturally in nitrification and dentrification
causes ozone depletion - 5Particulate MatterPMx
microscopic solid or liquid matter in the atmosphere
naturally occurring: volcanos, fires, dust storms
changes nutrient balance in water forms - 6How to reduce particulate matter?limit fumes
increase auto standards
public transportation - 7Ozonesecondary pollutant
formed from burning fossil fuels (powerplants and cars) and releasing VOC
can: irretate respiratory, cause asthma and bronchitis, cause heart attacks and cardiopulmonary problems - 8Peroxyacl NitratesPANS
secondary pollutant
breaks into radicals and NO2, causes far spread from origin
causes respiratory & immune problems, eye irritation, & damaging to crops - 9How to reduce PANS?reduce fossil fuel reliance
reduce waste incineration
limit wood burning in home construction - 10Volatile Organic CompoundsVOCs
organic chemicals w/ high vapor pressure
high pressure comes from high boiling point
causes sick building syndrome - 11Volatile Organic Compounds health effectseye nose throat irritation
headaches, nausea
damsging to liver, kidney, nervous system
cancer - 12Sulfur OxideSOx
most commonly found as SO2
colorless gas w/ choking odor
dissolves in water=acidic solution
main sources- FF burning, cars, volcanoes, hot springs, forrest fires
contributes to acid rain & toxic to plants - 13How to reduce sulfur oxide?use low sulfur coal
"wash" coal
put scrubbers in smokestacks - 14Nitrogen OxideNOx
term for NO and NO2
occurs in high temp combustion like forrest fires, lightning, volcanoes
contributes to acid rain
NOx+VOC= photochemical smog - 15Leadremoved from gas in 1975
removed from paint in 1977
causes:
ammonia
pregnancy problems
High blood pressure - 16Tobacco Smokecontains 5,000 chemical compounds
60 known carcinogens
responsible for cancers
linked to leukemia, strokes, and heart attacks - 17Asbestosstarted as steam engine lining
inexpensive, durable, flexible
acts as insulating & fireproofing
Leads to lung cancer, asbestosis
Regualted under clean air act - 18Carbon Monoxide- Indoorcombines w/ hemogloben to block blood's oxygen carrying capacity
cooking in developing countries
Contributes to cancer, low birth rate, tuberculosis, increased infant mortality - 19Formaldehydecarcinogen linked to nasal & lung cancer
in paper products, insulation, pressed wood, deoderant - 20Persistant Organic PollutantsPOPS
organic compunds resistant to enviornmental degration
used as pestisides
emitted from burning hospital/municipal/ hazardous waste, cars, coal and wood - 21How do POPs exert effectslong range transport- travel far from source
bioaccumulation- concentrates to danger levels - 22Radoninvisible radioactive gas from radium decay
radium found in rock (Uranium)
causes lung cancer - 23Reduce radon levelssealing concrete slab floors
sealing basement foundations
increase indoor ventillation - 24Case Study: Reading Pronggranite rock under PA, NJ, NY
contain high uranium
causes high indoor levels in homes - 25Case Study: World Trade Centerterrorist attacks release dust into air
highest dioxin concentration ever, 6x highest ever in US
causes sickness and death
