Air Quality Australia: Future Research Directions

K.M. Emmerson, M.F. Hibberd, M.E. Cope and P.N. Holper.
In May 2014, CSIRO, in consultation with the jurisdictions, organised a Symposium to consider future directions of research for air quality in Australia. The Symposium invited sixty nine representatives from the States and Territories, the Commonwealth, universities, CSIRO, ANSTO and the Bureau of Meteorology. The State, Territory and the Commonwealth environment agencies laid out their priorities relating to the management of air quality and science areas requiring research. The areas included human health and exposure, modelling tools, observations and field studies, emission inventories and a national air quality database. This paper presents a summary of the discussions and recommendations from the Symposium.

Biofiltration for emission and odour control

Ryan T.
Odour management is a significant challenge for industrial and municipal operations. For several decades biofiltration has been used worldwide for emission and odour control. Because of its ability to adapt to a wide variety of Volatile Organic Compounds (VOC’s) the technology has been applied across a range of industries. The classic quote from the movie Field of Dreams “If you build it they will come.” is now perhaps over used but it neatly sums up the basic principal of the operation of biofilters. That is, appropriate bacteria will naturally colonise biofilter media in response to the VOC’s that are introduced. Biofilters have evolved from simple and crude soil beds to more refined soil beds, through to packaged biofilters that provide far greater control of critical media parameters such as moisture content, temperature and consistent air flow. Now a recent development refines the concept further, while substantially negating the issue of media degradation. Two case studies are presented where traditional soil beds have been replaced with packaged biofilters resulting in vastly improved outcomes.

Review of evidence on health aspects of air pollution – REVIHAAP Project

Goldstone M
The REVIHAAP technical report published in 2013 presents answers to 24 questions relevant to reviewing European policies on air pollution and to addressing health aspects of these policies. The answers were developed by a large group of scientists engaged in the WHO project “Review of evidence on health aspects of air pollution – REVIHAAP”. The experts reviewed and discussed the newly accumulated scientific evidence on the adverse effects on health of air pollution, formulating science-based answers to the 24 questions. Extensive rationales for the answers, including the list of key references, are provided. However in this review, these are skipped and anybody who is interested is referred to the technical report, which can be found at http://www.euro. who.int/__data/assets/pdf_file/0004/193108/ REVIHAAP-Final-technical-report-final-version.pdf or simply by searching “REVIHAAP”. The review is an extract of the questions and answers, which are remarkably pertinent to the current establishment of a National Clean Air Agreement. Whilst the discussion paper references this report, it remains to  be seen if in light of the answers given here, the proposed agreement goes far enough.

Working towards a National Clean Air Agreement Discussion Paper

Jack Chiodo – Chairman of the CASANZ Policy SIG
The Clean Air Society of Australia and New Zealand (CASANZ) is a non-government, non-profit organisation that brings together professionals working across a broad range of air quality management fields. Formed in 1966, the Society’s members have been intimately involved with the evolving management of air quality in Australia and New Zealand. Various members of the Society have worked in all levels of government, conducted research in Universities and CSIRO, and worked as air quality consultants. The Society performs important roles in information and technology transfer, and training. CASANZ welcomed this opportunity to provide feedback on the Discussion Paper Working Towards a National Clean Air Agreement. This submission includes the considered views of the Society, including feedback from members to a short survey on their views on the various issues raised in the Discussion Paper.
