Air Pollution
-
Sources
Transport
- All forms of motorised transport cause some environmental problems, but road vehicles are the most polluting.
- Exhaust fumes - a mixture of different gases, including carbon monoxide (a toxic has).
- In sunny conditions, the gases from exhausts form a photochemical smog.
- Smog - smoke + fog, and contains ozone (valuable high up in the stratosphere, but harmful near the ground).
Electricity Generation
- All forms of electricity generation have some effect on the environment
- The combustion of coal, oil accounts for much of the airborne pollutants (can cause acid rain).
- *The harmful fumes may be cleaned up.
- Wind and wave power have far less effect than generation from fossil
fuels.
Industry
- Smokestacks do not remove pollutants but simply boost them higher into the atmosphere
- These pollutants may then be transported over large distances and produce adverse
effects in areas far from the site of the original emission (acid rain).
Other sources:
Agriculture:
90% ammonia emissions
80% methane emissionsNatural phenomena:
release pollutants into the atmosphere
- volcanic eruptions
- sand storms
Business, public buildings, households
50% carbon monoxide emissions

Definition
Air Pollution is contamination of the atmosphere by gaseous, liquid, or solid wastes or by-products that can endanger the health and welfare of humans, plants and animals.
Asthma
increased hospital visits
worsened symptoms
adverse birth outcomes
breathing problems
decreased lung growths (kids)
lung cancer
early death
Acid Rain
acid precipitation - acid snow,acid hail, acid fog and acid mist, acid rain.
toxic metals (aluminium and lead) in the water
Effects:
humans (Alzheimer's disease)
trees ( leaves or
needles)
animals (no fish)
fish (toxic metals in the water)
rocks, walls (o "lichen deserts")
In your house
