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
Determination of the fate of dissolved organic nitrogen in biological nutrient removal (BNR) processes and development of appropriate treatment technologies. The aim of this project is to better characterise the dissolved organic nitrogen (DON) in sewage treatment plant influent, determine its fate in biological nutrient removal (BNR) plants, and to evaluate and develop an appropriate treatment technology.
As a result of tightening effluent N licence requirements for sewage treatment plants, ....Determination of the fate of dissolved organic nitrogen in biological nutrient removal (BNR) processes and development of appropriate treatment technologies. The aim of this project is to better characterise the dissolved organic nitrogen (DON) in sewage treatment plant influent, determine its fate in biological nutrient removal (BNR) plants, and to evaluate and develop an appropriate treatment technology.
As a result of tightening effluent N licence requirements for sewage treatment plants, the dissolved organic nitrogen (DON) fraction has become extremely important. In many cases, the DON forms the major fraction of the effluent N, and is constraining further reductions in licence specifications, and in some cases it is the cause of failure to meet licence.
DON is refractory (un-biodegradable), very poorly characterised, its fate in conventional biological treatment processes not known, and its eventual impact on the environment unknown. Considering its importance, it is critical that these issues are addressed. This proposal intends to address some of them.
This project is an APA(I) PhD student project.Read moreRead less
Development of a Nitrogen Removal Technology to Integrate with the Novel ‘EnRec’ Energy Recovery Sewage Treatment Process. The aim of this project is to develop a nitrogen removal technology to integrate with the novel energy recovery sewage treatment process, EnRec. EnRec is presently being developed as part of a collaborative R&D activity between the partners, and is partly supported by a Queensland Government (QSEIF) grant which was awarded in November 2002.

The aim of this project is to develop a nitrogen removal technology to integrate with the novel energy recovery sewage treatment process, EnRec. EnRec is presently being developed as part of a collaborative R&D activity between the partners, and is partly supported by a Queensland Government (QSEIF) grant which was awarded in November 2002.
One important issue yet to be addressed is how to achieve nitrogen removal in the EnRec process. One of the major differences between the EnRec process and conventional sewage treatment technology is that the main process reactor is anaerobic, thus eliminating aeration costs and enabling methane production. However, anaerobic treatment processes do not provide significant nitrogen removal, and thus it will be necessary to integrate a nitrogen removal technology with the main energy recovery process. This is the aim of this project.
The project is an APA(I) PhD student project.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
Managing the social, environmental & economic impacts of high density-living within inner-urban sub-tropical environments. Higher-density (HD) living is a popular strategy for managing urban growth (i.e., reducing greenhouse gas emissions). In sub-tropical environments, it represents a significant change from the traditional suburb, but provides a potential solution to the impacts of population growth on resources/infrastructure. By identifying the impacts associated with HD living & developing ....Managing the social, environmental & economic impacts of high density-living within inner-urban sub-tropical environments. Higher-density (HD) living is a popular strategy for managing urban growth (i.e., reducing greenhouse gas emissions). In sub-tropical environments, it represents a significant change from the traditional suburb, but provides a potential solution to the impacts of population growth on resources/infrastructure. By identifying the impacts associated with HD living & developing strategies (including design solutions & impact management strategies) to enhance the sustainability of HD, this research will have immediate and long-term triple bottom line benefits for Australia - encouraging the uptake of HD living achieving an environmentally sustainable Australia (Research Priority 1).

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
Chemicals in compostable food contact paper packaging materials. The aim of this project is to understand the presence of persistent chemicals in recyclable and compostable food contact materials (FCMs). These types of products are destined for recycling or biowaste streams that bridge the gap from take-make-dispose and into a circular economy.

The aim of this project is to understand the presence of persistent chemicals in recyclable and compostable food contact materials (FCMs). These types of products are destined for recycling or biowaste streams that bridge the gap from take-make-dispose and into a circular economy. Currently, the knowledge of the chemicals in these products is limited but we need to ensure that they are safe and do not unnecessarily contaminate resource recovery streams. It is expected that this project will develop a framework that could be used by industry and government to prevent chemicals of concern persisting in a circular economy, providing environmental and economic benefits through reduced risk of chemical exposure and unnecessary remediation costs.Read moreRead less
