Degradation of Oestrogenic and Carcinogenic Substances in Water using alternative water treatment technologies- Membrane Technology and Photocatalysis. There is currently much concern about the release into the aquatic environment of oestrogenic and carcinogenic pollutants. Current conventional water treatment technologies are ineffective in removing them from our water supplies.

There is currently much concern about the release into the aquatic environment of oestrogenic and carcinogenic pollutants. Current conventional water treatment technologies are ineffective in removing them from our water supplies. This research proposes to investigate alternative water treatment technologies for the removal of these compounds of concern. The technologies to be investigated involve integrating membrane technology and titanium dioxide photocatalysis to produce a highly effective and efficient water treatment process. The effects of various parameters on degradation of the pollutants will be investigated and monitored using different analytical techniques.Read moreRead less
An evaluation of the environmental health risk of heatwaves associated with global warming. Global warming is associated with an increased frequency of severe weather events including frequent and severe heatwaves. Previous studies have demonstrated that heatwaves are amongst the most deadly disasters to affect the community. This study will identify those members of the community who are most at risk from heatwaves so that strategies may be identified and implemented by governments to protect t ....An evaluation of the environmental health risk of heatwaves associated with global warming. Global warming is associated with an increased frequency of severe weather events including frequent and severe heatwaves. Previous studies have demonstrated that heatwaves are amongst the most deadly disasters to affect the community. This study will identify those members of the community who are most at risk from heatwaves so that strategies may be identified and implemented by governments to protect those people during severe heatwave conditions. The direct benefit to the community will be reduced mortality and morbidity and the consequential reductions in the cost of community and health support services.Read moreRead less
Photodegradation of Oestrogenic Pollutants in the aquatic environment. Recent media attention has highlighted the problem of oestrogenic pollutants in the aquatic environment. This research proposes to investigate Photocatalysis of oestrogens in water using the magnetic titanium dioxide particles developed at the Centre for Particle and Catalyst Technologies in the University of New South Wales, Sydney. The natural oestrogens 17b-oestradiol, oestrone and oestriol and the synthetic oestrogen 17a- ....Photodegradation of Oestrogenic Pollutants in the aquatic environment. Recent media attention has highlighted the problem of oestrogenic pollutants in the aquatic environment. This research proposes to investigate Photocatalysis of oestrogens in water using the magnetic titanium dioxide particles developed at the Centre for Particle and Catalyst Technologies in the University of New South Wales, Sydney. The natural oestrogens 17b-oestradiol, oestrone and oestriol and the synthetic oestrogen 17a-ethynyl oestradiol (the main constituent of the contraceptive pill) will be investigated in the photocatalytic system. Degradation will be monitored using various analytical techniques. Other commercial catalysts will also be investigated and compared with the magnetic catalyst and previous catalysts tested.Read moreRead less
Assessment of bentonites as remediating agents for metal contaminated soils using innovative bioavailability reduction technology. The project seeks to carry out research on innovative, economically sustainable risk-based solutions (soil amendments) for metal-contaminated soils and methods for assessing the potential risk/bioavailability of soil bound metals. The work will determine factors affecting the reactivity, mobility and bioavailability of metals in Australian soils and clays and method ....Assessment of bentonites as remediating agents for metal contaminated soils using innovative bioavailability reduction technology. The project seeks to carry out research on innovative, economically sustainable risk-based solutions (soil amendments) for metal-contaminated soils and methods for assessing the potential risk/bioavailability of soil bound metals. The work will determine factors affecting the reactivity, mobility and bioavailability of metals in Australian soils and clays and methods by which these can be controlled. Remediation options, such as natural clay amendments to reduce metal bioavailability, will be assessed against in vivo and in vitro bioavailability assays in order to develop cost effective, risk-based remediation strategies and assessment protocols for urban and rural contaminated soils.Read moreRead less
Development of a framework for assessing the vulnerability of eco-environmental health to climate change. Many governments and international agencies are increasingly concerned about the potential eco-environmental and public health impact of emerging issues such as climate change, urbanisation and loss of biodiversity. However, it remains unclear how the vulnerability of eco-environmental health to these changes can be assessed and which framework should be adopted. This research will focus on ....Development of a framework for assessing the vulnerability of eco-environmental health to climate change. Many governments and international agencies are increasingly concerned about the potential eco-environmental and public health impact of emerging issues such as climate change, urbanisation and loss of biodiversity. However, it remains unclear how the vulnerability of eco-environmental health to these changes can be assessed and which framework should be adopted. This research will focus on the development of a framework for assessing the vulnerability of eco-environmental health to climate change, and will provide valuable information to help identify knowledge and information gaps in the risk assessment of major eco-environmental health hazards.Read moreRead less
The effect of dissolved organic matter on the toxicity and bioavailability of metals in tropical freshwater ecosystems. Mine waste materials in tropical Australia, including historical, current and future operations, represent one of the threats to the quality and biodiversity of tropical freshwater ecosystems. Dissolved organic carbon (DOC) is thought to influence metal toxicity. In order to adequately understand the risks of priority metals and metalloids from mining and other activities (eg. ....The effect of dissolved organic matter on the toxicity and bioavailability of metals in tropical freshwater ecosystems. Mine waste materials in tropical Australia, including historical, current and future operations, represent one of the threats to the quality and biodiversity of tropical freshwater ecosystems. Dissolved organic carbon (DOC) is thought to influence metal toxicity. In order to adequately understand the risks of priority metals and metalloids from mining and other activities (eg. urban development) to tropical freshwater ecosystems, it is essential that the role of DOC is quantified. The outcomes of this project will provide improved metal risk assessment methodologies; quantitative understanding of the relationship between DOC and the bioavailability and toxicity of key metals such arsenic, aluminium, cadmium, copper, uranium and zinc.Read moreRead less
Integrated and precautionary approach for assessing complex environmental health impacts. It is important to develop an innovative and systematic approach to the improvement of environmental health impact assessment for emerging complex environmental hazards. It has become increasingly apparent that traditional risk assessment methods are no longer suitable for assessing the health impact of emerging global environmental issues such as climate change and ecosystem degradation. The novelty of thi ....Integrated and precautionary approach for assessing complex environmental health impacts. It is important to develop an innovative and systematic approach to the improvement of environmental health impact assessment for emerging complex environmental hazards. It has become increasingly apparent that traditional risk assessment methods are no longer suitable for assessing the health impact of emerging global environmental issues such as climate change and ecosystem degradation. The novelty of this proposal lies in its intention to create fundamental knowledge on an integrated and precautionary approach for assessing complex and emerging environmental health risks by development of a conceptual framework for integrated environmental health impact assessment.Read moreRead less
