Formation, degradation and migration of a yet unidentified POP source. Australia has recently ratified the Stockholm Convention, targeting persistent organic pollutants (POPs) for global reduction and elimination. A significant gap exists, however, in understanding sources and pathways of POPs in Australia, and subtropical/tropical environments. Previous research has shown an extensive POP contamination in coastal Australia, and exposure of biota to elevated levels. The present study will evalua ....Formation, degradation and migration of a yet unidentified POP source. Australia has recently ratified the Stockholm Convention, targeting persistent organic pollutants (POPs) for global reduction and elimination. A significant gap exists, however, in understanding sources and pathways of POPs in Australia, and subtropical/tropical environments. Previous research has shown an extensive POP contamination in coastal Australia, and exposure of biota to elevated levels. The present study will evaluate the formation, degradation and migration of POPs, and their significance to Australia's past, present and future emissions. The outcomes will allow identification of sources, their prioritization for elimination and exposure prevention, and ultimately serve to protect the environment and human health in Australia.Read moreRead less
The role of bush fires in the formation and fate of dioxin like chemicals in Australia. A global (POPs) treaty signed by more than 100 nations targets the reduction and elimination of dioxins, which are persistent, bioaccumlative and highly toxic to humans. Bushfires have been suggested as the major source of dioxins in Australia. Experimental data indicate bushfires may not represent the actual sources of dioxin. Our aim is to experimentally establish the levels of dioxins formed and re-emi ....The role of bush fires in the formation and fate of dioxin like chemicals in Australia. A global (POPs) treaty signed by more than 100 nations targets the reduction and elimination of dioxins, which are persistent, bioaccumlative and highly toxic to humans. Bushfires have been suggested as the major source of dioxins in Australia. Experimental data indicate bushfires may not represent the actual sources of dioxin. Our aim is to experimentally establish the levels of dioxins formed and re-emitted from bushfires in Australia. The results will assist to make informed decisions that lead to effective action for reducing dioxin contamination in Australia, fulfilling the treaty requirements and protecting the population and environment.

Atmospheric fate and processes of semi-volatile organic compounds in tropical climates. The outcomes from this study will contribute fundamental and quantitative information for evaluation of the fate of semi-volatile organic compounds (SOCs) in tropical systems, including Australia's World Heritage ecosystems such as rainforest and the Great Barrier Reef. The study addresses key international knowledge gaps with respect to the influence of climate on SOC atmospheric fate. Australia's geographic ....Atmospheric fate and processes of semi-volatile organic compounds in tropical climates. The outcomes from this study will contribute fundamental and quantitative information for evaluation of the fate of semi-volatile organic compounds (SOCs) in tropical systems, including Australia's World Heritage ecosystems such as rainforest and the Great Barrier Reef. The study addresses key international knowledge gaps with respect to the influence of climate on SOC atmospheric fate. Australia's geographical location within the tropical belt provides an ideal opportunity for leading this field of research and contributes relevant data for its commitment under the Stockholm Convention.Read moreRead less
The role of early life history on the survival of coral reef fishes - opening the Black Box. A fundamental unanswered question in marine ecology and fisheries management is - what influences the number of individuals that survive the larval phase to join a reef population? Theoretical studies show that small changes in the quality of offspring can lead to large changes in the numbers surviving the larval phase. What aspects of offspring quality determine who survives is largely unknown. We use ....The role of early life history on the survival of coral reef fishes - opening the Black Box. A fundamental unanswered question in marine ecology and fisheries management is - what influences the number of individuals that survive the larval phase to join a reef population? Theoretical studies show that small changes in the quality of offspring can lead to large changes in the numbers surviving the larval phase. What aspects of offspring quality determine who survives is largely unknown. We use a multidisciplinary approach to explore what influences the quality of offspring spawned by adults, and whether offspring traits prior to or at hatching determine the identity of individuals that survive to join the reproductive population.Read moreRead less
