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.

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 World Heritage Great Barrier Reef sustains unique marine biota such as dugongs and turtles. High concentrations of harmful dioxins have been reported recently in dugongs. However, the impacts of these contaminants on the health of dugong and turtle populations remain unknown. This study will redress the general lack of toxicological information available for reptiles and dugongs. This includes assessments of exposure, pathways as well as toxicological responses to the compounds of concern, to provide a robust assessment of the risks associated. The outcomes will guide management policy designed to protect the environmental health of Queensland's Marine Parks.Read moreRead less
Development of a risk assessment tool to minimise mixed metals toxicities from mine tailings. Research based on animal uptake from mine tailings is required to quantify comparative bioavailability of mixtures of metals to provide data for mine rehabilitation design during the planning stage. Such data also provides risk assessment in humans. The optimum balance is minimum environmental effects from the rehabilitated mine structure versus minimised cost through planning prior to project commencem ....Development of a risk assessment tool to minimise mixed metals toxicities from mine tailings. Research based on animal uptake from mine tailings is required to quantify comparative bioavailability of mixtures of metals to provide data for mine rehabilitation design during the planning stage. Such data also provides risk assessment in humans. The optimum balance is minimum environmental effects from the rehabilitated mine structure versus minimised cost through planning prior to project commencement. The significant cost of mining ore bodies, particularly by modern open cut methods, is the removal of rock and soil. The research on animal toxicity testings will provide a tool to more accurately detail mine rehabilitation and give quantitative indicators for closure.Read moreRead less
Dynamic spatio-temporal approach to environmental health modelling. Maintenance and enhancement of environmental health (EH) is an important aspect of sustainable development (SD).

Maintenance and enhancement of environmental health (EH) is an important aspect of sustainable development (SD). There has been an increasing realisation that an appropriate modelling approach needs to be developed to measure and promote EH. However, a framework for the development of EH models to facilitate environmental management decision-making has not been attempted to date. This research aims to increase fundamental knowledge on the relationship between environmental exposures and community well-being, to develop a dynamic and systematic approach to EH modelling, and to assess implications of EH models in the planning of SD and environmental management.Read moreRead less

Protecting and promoting community well-being and population health is an essential aspect of sustainable development (SD). It is critical, therefore, to develop rigorous environmental health indicators (EHIs) to provide solid bases for the planning of SD and environmental management decision-making. However, a framework for the development of EHIs has not been attempted. This research aims to increase fundamental knowledge on the relationship between EHIs and SD, to identify a core and extended set of EHIs, and to assess implications of EHIs in the planning of SD and environmental management. A framework for identification and application of EHIs will be developed.Read moreRead less

Worldwide, huge fresh water shortage problems force us to recycle/reuse water. For Australia, this is an urgent issue due to our limited fresh water resources. In recent years, rapidly diminishing fossil fuel supplies and dramatically accelerated global warming gives society no alternative but adopt renewable, clean energies. Globally, there is a united front calling for action to address these problems. However, a practical solution to the issues can only be found when economically viable alternative technologies are developed. This project aims to tackle the biggest obstacle - the low sunlight conversion efficiency. The success of the project will result in economically viable water treatment and solar energy conversion technologies. Read moreRead less
