  1. Particulate Matter Pollution in Australia Melita Keywood and Martin Cope 22 October 2013 Centre for Australian Weather and Climate Research/CSIRO Marine and Atmospheric Research

  2. Air Quality in Australia Although air quality in Australia is generally good Australians consistently rank air pollution as a major environmental concern In 1998, the Ambient Air Quality National Environment Protection Measure (AAQ NEPM) was established to set national ambient air quality standards. These standards cover six pollutants – particles (PM10), ozone, sulfur dioxide, nitrogen dioxide, carbon monoxide and lead. State Regulatory Authorities (EPA) –responsible for monitoring and reporting 1998 –main problems are ozone and particles in urban centres, winter time PM10 exceedences due to domestic woodheater emissions

  3. A success story: Launceston PM10

  4. Launceston Woodheater Replacement Programhttp://www.launceston.tas.gov.au/lcc/index.php?c=172 http://epa.tas.gov.au/documents/annual%20nepm%20report%20air%20quality%20tasmania%202011.pdf

  5. National Plan for Clean Air In 2011 the Council of Australian Governments (COAG) agreed that the COAG Standing Council on Environment and Water would develop a National Plan for Clean Air to improve air quality, and community health and well being, to be delivered to COAG by the end of 2014. Focus on particles- greatest health benefits to be gained Exposure based http://www.scew.gov.au/coag-strategic-priorities/national-plan-clean-air

  6. 2013 Senate Enquiry • 154 submissions • Recommendations • Collection of additional data on ultrafine particles concentration • Pollution monitoring should accurately capture population exposure for communities and homes proximate to pollution point sources. • Buffer zones be used to protect populated areas from large point-source polluters. • Coal mining • Woodheaters • http://www.aph.gov.au/Parliamentary_Business/Committees/Senate/Community_Affairs/Completed_inquiries/2010-13/airquality/report/index

  12. Secondary organic aerosols • What proportion of the SOA is anthropogenic (VOC control) vs. biogenic (NOx control)? The Centre for Australian Weather and Climate ResearchA partnership between CSIRO and the Bureau of Meteorology

  13. Conclusions • Particles continue to be a significant air quality issue in Australia • The development of the National Plan for Clean Air will focus on particles because of the size of the health benefits to be gained. • Process understanding can lead to successful policy implementation and outcomes e.g. Launceston PM10 reduction • Sydney -particle formation and growth events occur on 50% of days in Sydney • Sydney > 50% of secondary organic aerosol is formed from oxidation of biogenic VOCs- requires different controls than anthropogenic VOCs

  14. Opportunities for China-Australia Collaboration • Australia-China Council Grants Program- annual competitive grants program, the Australia-China Council supports projects across China, Hong Kong, Taiwan, Macau and Australia that deliver tangible outcomes for Australia-China relations in the priority areas of Economics and Trade, Society and Culture and Education and Science http://www.dfat.gov.au/acc/grants/index.html • China Scholarship Council Funding – for PhD Students and Visiting Scholars--Chinese Ministry of Education (MoE) Memorandum of Understanding • Australia-China Science and Research Fund (ACSRF) provides support for strategic science and research collaboration of mutual benefit to Australia and China http://www.innovation.gov.au/Science/InternationalCollaboration/ACSRF/Pages/default.aspx • Australia China Science Academies Symposia Series
