Health effects

In August 2015 the Chief Health Officer's Air Pollution Expert Advisory Committee (EAC) expanded to allow for the provision of advice to the Chief Health Officer on a wider array of potential environmental risks to public health.

Sources of Air Pollution

Coal-fired power stations are known emitters of fine particles PM2.5 (PM2.5 stands for particles of a size of 2.5 microns or less, i.e. 0.025 mm) and pollutant gases such as SOX and NOX. ANSTO researchers have developed techniques to determine the contributions of eight coal-fired power stations, which burn over 25 MT/year (yr) of low grade sulfur coal, to the PM2.5 mass loading in the greater Sydney metropolitan area.

EPA: "Causes of air pollution"

Air pollution is caused by

  • natural sources such as bushfires, dust storms, sea salt and pollen
  • domestic activities such as burning wood fires, including using wood heaters, fuel-powered garden equipment, and portable fuel containers
  • commercial businesses such as spray painters, printers, quarries, service stations
  • industrial activities such as coal mining, oil refining and power generation
  • on-road motor vehicles such as buses, cars and trucks
  • off-road vehicles and equipment such as dump trucks, bulldozers and marine vessels

Air Pollution from Motor Vehicles (across Sydney, RMS, 16/2/18 4:26 pm)

Motor vehicles are an important contributor to emissions, contributing
14 per cent of PM 2.5 , and 62 per cent of nitrogen oxides. NSW Government (RMS) Sydney’s air quality Fact sheet, Summer 2018

How does NO2 affect me?

Short and long term exposure to NO2 has been linked with an increased risk of respiratory problems. People with asthma, young children and older adults have an increased sensitivity to its effects (1). The secondary pollutants caused by the presence of NO2 in the atmosphere also have their own adverse effects. PANs are an irritant, nitric acid causes acid rain and particulate matter and O3 cause respiratory problems. Sydney’s Air Quality Info
