Air Quality
The nature of Air Quality Air pollution is the
accumulation of impurities in the air. Air
quality becomes a problem when the extra
pollutants in the air are poisonous or
concentrated enough to affect life on
Earth. Pollutants can have an unpleasant odour,
irritate the senses, reduce visibility and damage
property. They can even cause death.

• Things that affect Air Quality
• Motor Vehicles
• Motor Vehicles are the most significant source of
  Australia's air pollution
• Power Stations
• Coal fired Power Stations generate 93 of NSWs
  energy and is a major source of air pollution
• Indoors
• Cigarette smoke, dust mites, moulds and
  pesticides are a major cause of illness in
  Australia

The responses by individuals, groups and
governments to Air Quality Up until the 1990s,
Australia had no national air quality standards.
The National Environment Protection Measure
(NEPM) for outdoor air quality now sets maximum
concentrations. The standards are based on the
need to protect human health. The NSW government
now monitors Air Quality around the state. For

• What can we do to improve Air Quality?
• Improve public transport so it is convenient,
  safe, reliable and cheap
• Use some petrol taxes to subsidise improvements
  to public transport
• Restrict new housing developments if access to
  public transport is poor
• Provide more transit and bus lanes
• Encourage transport of freight by train
• Implement stricter emission controls for motor
  vehicles and industry
• Provide incentives for research into renewable
  energy technologies
• Provide financial incentives for householders to
  install solar hot-water heaters
• Use the polluter pays' principle, whereby people
  pay for the pollution and waste they produce.
