Elevated levels of NO2 are of concern to our urban communities as it affects human health. Particulate matter 10 μm or less in diameter (PM10) is also known to have adverse effects on human health and the environment.
This dataset presents a spatial distribution of the modelled annual average NO2 and PM10 concentrations in the year 2008, highlighting pollution hotspots in the Greater Sydney area.
Modelled concentrations were generated by adapting ERG's London Air Quality Toolkit (LAQT) for Sydney, using local meteorology and emissions data. The model is a simplified version, owing to the limitations in spatial resolution of available emissions data.
The model indicates that the NO2 concentrations are highest in areas with large volumes of traffic and industrial activity, but decline to the west and North where there is a lower density of on-road mobile sources.
