Air Quality
Indicator Rationale
Clean air is cited as a fundamental element in Victoria’s Sustainability Framework, “Our Environment, Our Future” (2005) and this indicator provides a measure of the state of the environment in terms of air quality. It is also an indirect measure of population exposure to suspended particles and noxious gases (United Nations, 2003). High population density and the concentration of industry, households, industry power stations and transportation (motor vehicles) exert great pressures on local environments (United Nations, 2003).
However, due to prevailing weather patterns and topography, the effects of air pollution may be felt off site, far from where they were generated.
