INDOOR AIR POLLUTION
OUTDOOR AIR POLLUTION
Formaldehyde
Six Criteria Pollutants
Particulate Matter
Sulfur Dioxide (SO2)
Carbon Monoxide
Nitrogen Oxides (NOx)
Radon
Particulate Matter
Asbestos
Caron Monoxide (CO)
Exposure causes lung cancer
Ozone (O3)
Solution: Increase ventilation
Lead (Pb)
Other Air Pollutants
Exposure causes lung cancer
VOCs
From burning coal- causes
neurological damage
Mercury
Component of photochemical
smog
From paint- causes
neurological damage
Poor air quality- Generally
respiratory irritants
Described as point source/
non-point source
Secondary pollutant- VOCs
+ H2O + sunlight
May be formed as primary or
secondary pollutants
AIR POLLUTION
ACID DEPOSITION
Reactions:
NO2 + H2O  HNO3
SO2 + H2O  H2SO4
Secondary pollutant in the
troposphere formed from a
reaction with water
Leaches aluminum ions from
the soil
Damages plant tissues
Erodes buildings and statues
Lowers the pH of surface
waters
OZONE DEPLETION
Loss of ozone concentration
due to CFCs
Thinning allows UV radiation
to reach Earth’s surface
Plant/ Crop Damage
Loss of phytoplankton
UV radiation causes DNA
damage
Skin Cancer
Sun Burns
Cataracts
Occurs in the stratosphere
Infrared radiation
GREEN HOUSE GASES
Water (H20)
Non- anthropogenic/ most
abundant
Carbon Dioxide (CO2)
Burning fossil fuels/
deforestation/ decomposition
Methane (CH4)
Landfills/ cow flatulence/ rice
farms
Nitrous Oxide (N2O)
Denitrification of inorganic
fertilizers
CFCs
Propellants/ refrigerants
CFCs react in the presence of
UV radiation- chlorine atom
attacks ozone molecule
GREENHOUSE GASES
Tropospheric Ozone (O3)
Secondary pollutant that
contributes to smog but also
has heat trapping potential
