Cover Story: In this study, a coupling of the Conformal Cubic Atmospheric Model and the Chemical Transport Model (CCAM-CTM) was undertaken, with 11 emission scenarios segregated from the 2008 New South Wales Greater Metropolitan Region (NSW GMR) Air Emission Inventory, to investigate major source contributions to ambient PM2.5 and exposure. The natural and human-made sources were found to contribute 60% (3.55 µg/m3) and 40% (2.41 µg/m3) to the population-weighted annual average PM2.5 (5.96 µg/m3), respectively. The major source groups “wood heaters”, “industry”, “on-road motor vehicles”, “power stations”, and “non-road diesel and marine” account for 31%, 26%, 19%, 17%, and 6% of the total human-made sources contribution, respectively. These quantitative results can be the basis for air quality management interventions that aim to deliver improved public health outcomes. View this paper.
