Abstract
Research has shown for some time that high levels of air
pollution can exacerbate illness. More recently, evidence
has emerged about how air pollution at much lower levels
can also affect the health of susceptible people, such as
those with asthma, chronic obstructive pulmonary disease
or coronary artery disease. NSW Health and the Department
of Environment and Conservation have started Australia’s
most comprehensive air quality warning system to ensure
residents of Sydney, the Illawarra and the lower Hunter
can take action to stay healthy at times of low, medium
and high air pollution.
