AIR POLLUTION
Brittney Vandenberg
Two main sources of pollution in
urban areas
 Transportation and fuel
combustion in stationary
sources, including residential,
and commercial.
 Industrial heating and cooling
and coal-burning power
plants.
Everyday air pollutants
 Air pollution occurs everywhere.
 Poor ventilation causes air contaminants to become trapped
inside.
 Some sources of indoor air pollutants may include:
 telephone and electrical cables,
 air conditioning systems and ducts,
 copying machines,
 mold,
 cleaning fluids,
 carpet,
 vinyl molding,
 building materials,
 cigarette smoke,
 latex caulk and paint,
 linoleum tile, and
 furniture.
Pollution damage to plants
 Pollutants such as sulfur dioxide, nitrogen oxides, ozone and
PANs (peroxyacl nitrates), cause direct damage to leaves of crop
plants and trees when they enter leaf pores (stomates).
 Chronic exposure of leaves and needles to air pollutants can also
break down the waxy coating that helps prevent excessive water
loss and damage from diseases, pests, drought and frost.
 Air pollution can affect soil moisture levels.
 It can also effect the salt levels in the soil. Too much salt in the
soil is toxic to plants. It also causes the soil surface to compact,
and crust over.
How pollution effects animals
 Three ways animals are effected by air pollution is:
 they can breathe in gases or small particle,
 eat particles in food or water,
 absorb gases through the skin.
Pollution effects on animals cont.
 Earthworms and animals moist skin is affected the
most.
 Animals are affected much the same as humans are
 It affects the breathing of animals.
 Its especially dangerous if it contains metal; they build
up high levels in the body tissues.
 Acid rain- effects acidity of water and decreases
number of trees that provide shelter.
Effects on people’s health
 short-term effects:
 irritation to the eyes, nose and throat
 upper respiratory infections such as bronchitis
and pneumonia.
 Other symptoms:
 Headaches
 nausea, and allergic reactions.
 Aggravates medical conditions of individuals
with asthma and emphysema.
Effects on people’s health cont.
 Long-term health effects:
 chronic respiratory disease
 lung cancer
 heart disease
 damage to the brain, nerves, liver, or kidneys.
Ways to solve air pollution
 Use environmentally friendly energy
sources, such as:
 wind power
 hydro power
 solar power
 fusion power plants.
Ways you can reduce air pollution
 driving a car that gets at least 35 miles a
gallon
 walking
 bicycling
 using transit
 replace incandescent light bulbs with
compact fluorescent bulbs
 make your home more energy efficient
Ways you can reduce air pollution cont.
 buy only energy efficient appliances
 recycle newspapers, aluminum, and other
materials
 plant trees
 avoid purchasing products such as Styrofoam
that contain CFCs
 support much stricter clean air laws
 enforcement of international treaties to reduce
ozone depletion and slow global warming
