Seagrass tolerance of oil spills - scaling of pollution impacts. Seagrasses provide vital ecosystem services (such as sediment stabilisation and habitat provision) in Australian coastal waters. The contribution of pollutants to current seagrass decline is poorly understood. The Australian shipping industry is the 5th largest in the world but there is very little data on the impacts of petroleum hydrocarbons on intertidal seagrasses and hence no information for coastal resource managers to use in ....Seagrass tolerance of oil spills - scaling of pollution impacts. Seagrasses provide vital ecosystem services (such as sediment stabilisation and habitat provision) in Australian coastal waters. The contribution of pollutants to current seagrass decline is poorly understood. The Australian shipping industry is the 5th largest in the world but there is very little data on the impacts of petroleum hydrocarbons on intertidal seagrasses and hence no information for coastal resource managers to use in decision-making in the event of an oil spill. This project will assess the relative toxicities of a number of petroleum hydrocarbons on Australian seagrass species to provide necessary data for the development of effective management practice.Read moreRead less
Novel Molecular Markers for the Historical Source Tracing of Faecal Contamination in Urban Water Catchments. Protection of the microbiological quality of raw water systems is imperative to maintaining the safety of drinking water. Monitoring of water samples for the presence of microbes that indicate the presence of faecal pollution can be used to assess the possible threats to human health. The objective of this research is to apply molecular genetic methods to determine their effectiveness as ....Novel Molecular Markers for the Historical Source Tracing of Faecal Contamination in Urban Water Catchments. Protection of the microbiological quality of raw water systems is imperative to maintaining the safety of drinking water. Monitoring of water samples for the presence of microbes that indicate the presence of faecal pollution can be used to assess the possible threats to human health. The objective of this research is to apply molecular genetic methods to determine their effectiveness as tools for the tracking and tracing of faecal bacteria within drinking water catchments. We have chosen the spore-former Clostridium perfringens as an indicator of both long and short-term sewage contamination. It will enable us to predict the origin of contamination and thus identify potential sources of faecal pollution that require remediation.Read moreRead less
Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia ....Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia from invasive diseases. There is an urgency to undertake our research because global environmental change and increasing movements of people (particularly military personnel) from overseas regions where these diseases are endemic is increasing the vulnerability of northern Australia to the (re)establishment of mosquito borne diseases.Read moreRead less
Endocrine Disrupting Compounds: Novel tests for Analysis and Field Validation. This project will give community benefits from new analytical technology and research data to help minimise the threat of environmental contamination with endocrine-disrupting compounds (EDCs). Both urban and rural communities may feel the impacts of EDCs, with potential contamination occurring globally, affecting both wildlife and humans.

This project will give community benefits from new analytical technology and research data to help minimise the threat of environmental contamination with endocrine-disrupting compounds (EDCs). Both urban and rural communities may feel the impacts of EDCs, with potential contamination occurring globally, affecting both wildlife and humans. The main means of transport of EDCs is as contaminants in water and it is essential to learn the extent of contamination occurring in urban and rural water supplies to decide its significance. The research will involve a multi-disciplinary approach, with benefits falling into all four National Research Priorities of sustainability, good health, frontier analytical technology and national safety.Read moreRead less
Developing and validating an air quality assessment model for application in human exposure assessment, housing/urban planning and policy setting. At present there does not exist a model for assessing human exposure to airborne pollutants in places where people live, work and rest. In addition, experimental exposure assessments display large discrepancies dependent on the measurement method used. This research aims at developing and validating an air quality assessment model that would enable ....Developing and validating an air quality assessment model for application in human exposure assessment, housing/urban planning and policy setting. At present there does not exist a model for assessing human exposure to airborne pollutants in places where people live, work and rest. In addition, experimental exposure assessments display large discrepancies dependent on the measurement method used. This research aims at developing and validating an air quality assessment model that would enable predictions of air quality in various mircoenvironments for the purpose of exposure and risk assessment, housing and urban planning, and policy setting. This research will provide scientific foundation and a tool for developing future directions for management and control to protect the community and the environment.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
Heavy metal phytotoxicity in long-term contaminated soils: Implications for the development of Australian regulatory guidelines and realistic environmental risk assessment. Heavy metal contamination is a serious global environmental problem. There are >80,000 potentially contaminated sites in Australia alone with many of these sites in the urban environment and former mining areas. The current guidelines for phytotoxicity testing (National Environmental Protection Measure 1999) are based on tota ....Heavy metal phytotoxicity in long-term contaminated soils: Implications for the development of Australian regulatory guidelines and realistic environmental risk assessment. Heavy metal contamination is a serious global environmental problem. There are >80,000 potentially contaminated sites in Australia alone with many of these sites in the urban environment and former mining areas. The current guidelines for phytotoxicity testing (National Environmental Protection Measure 1999) are based on total metal concentrations that do not take into consideration of bioavailability and wide ranging Australian soil types. Serious concerns have been raised on the applicability of these guidelines and their protective limits in ecological risk assessment. This project aims at developing phytotoxicity guidelines applicable to a wide range of soil types common to Australia.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
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
