Summary
Remediation of PFAS contaminated soil using soil washing and immobilisation. This project aims to assess the applicability of soil washing and immobilisation as cost-effective techniques for the remediation of per- and poly-fluroalkyl substance (PFAS) contaminated Australian soils. The project expects to establish the efficacy of the remediation of a range of PFASs, including many polyfluorinated precursors of perfluorinated, chemically-persistent legacy pollutants which are of concern. The proj ....Remediation of PFAS contaminated soil using soil washing and immobilisation. This project aims to assess the applicability of soil washing and immobilisation as cost-effective techniques for the remediation of per- and poly-fluroalkyl substance (PFAS) contaminated Australian soils. The project expects to establish the efficacy of the remediation of a range of PFASs, including many polyfluorinated precursors of perfluorinated, chemically-persistent legacy pollutants which are of concern. The project will provide a scientific basis for understanding the benefits and limitations associated with soil washing and immobilisation techniques and a more comprehensive understanding of future liabilities associated with formation of PFASs from precursors remaining in remediated soils. Collaboration with stakeholders will ensure benefits are captured both commercially and environmentally, as well as removing a potential and on-going health threat to communities exposed to these contaminants.Read moreRead less
Innovative approaches to managing and understanding taste and odour in drinking water systems. Taste and odour (T/O) problems resulting from Cyanobacteria can change consumers' perception of product safety, resulting in many complaints, soaring management and treatment costs, and large financial losses, yet little is known about how they arise.
This project will provide the Australian Water Industry with cost-effective, sensitive, specific, rapid and practical tools for managing and understandi ....Innovative approaches to managing and understanding taste and odour in drinking water systems. Taste and odour (T/O) problems resulting from Cyanobacteria can change consumers' perception of product safety, resulting in many complaints, soaring management and treatment costs, and large financial losses, yet little is known about how they arise.
This project will provide the Australian Water Industry with cost-effective, sensitive, specific, rapid and practical tools for managing and understanding T/O episodes, and will also benefit the aquaculture and food sectors, and the research community. An improved ability to manage geosmin in drinking water, will also have positive repercussions on the Australian environment, by eliminating the need to use environmentally controversial control methods such as copper sulphate dosing.

Identifying cost-effective reforestation approaches for biodiversity conservation and carbon sequestration in southern Australia. The project will determine the reforestation approach that maximises the native biodiversity found in bushland/shrubland regrowth in South Australia, while maximising the carbon sequestered for the lowest cost. This project will use controlled planting experiments modifying tree/shrub diversity and plant density combined with species and carbon monitoring.
The effect of aerial spraying of two pesticides on semi-arid grasslands. The project will investigate how two pesticides, fipronil and metarrhizium, used to control locusts, affect semi-arid ecosystems by examining impacts on invertebrates, their predators, lizards and soil processes. The effects will be followed through time in a large scale experiment to determine recovery and compare each pesticide.
Carbon conundrum: Functional characterisation of organic matter-clay mineral interactions in relation to carbon sequestration. Carbon sequestration in soil has been recognised as one of the possible measures through which greenhouse gas emissions can be mitigated. The major processes involved in carbon sequestration in soil include chemical immobilisation of carbon with soil particles and physical protection in the pores of soil microaggregates. These two processes are mediated through the funct ....Carbon conundrum: Functional characterisation of organic matter-clay mineral interactions in relation to carbon sequestration. Carbon sequestration in soil has been recognised as one of the possible measures through which greenhouse gas emissions can be mitigated. The major processes involved in carbon sequestration in soil include chemical immobilisation of carbon with soil particles and physical protection in the pores of soil microaggregates. These two processes are mediated through the functional relationships of soil organic matter and clay mineral interactions in soils. This project investigates nanoscale organomineral association underlying microaggregate formation and stability, as well as the distribution and microbial decomposition of carbon within microaggregates using a suite of advanced spectroscopic, molecular and isotopic techniques.Read moreRead less
Drivers of the live pet trade in Australian reptiles. This project aims to understand the complex trade in live Australian reptiles. The global pet trade is a major threat to biodiversity.

Using surveillance of domestic and overseas online markets, and innovative statistical and simulation-based approaches to inform conservation decision-making, the expected outcome ....Drivers of the live pet trade in Australian reptiles. This project aims to understand the complex trade in live Australian reptiles. The global pet trade is a major threat to biodiversity. This project expects to generate critical new knowledge for combatting the current and future illegal trade in Australian wildlife. Using surveillance of domestic and overseas online markets, and innovative statistical and simulation-based approaches to inform conservation decision-making, the expected outcomes of this project include an enhanced capacity to conserve native species and to monitor and disrupt the complex illegal wildlife trade. This should provide significant benefits in terms of biodiversity conservation and safeguarding Australia’s unique and ecologically important native reptile species.Read moreRead less
Saving Nemo: Reducing animal use in toxicity assessments of wastewater. Every day, Australians produce ~5 billion litres of wastewater, which contains a cocktail of chemicals. Industries that discharge wastewater are required to assess chemical risks to the receiving environments by conducting whole animal direct toxicity assessments (DTA), which are expensive and pose an ethical dilemma. Our preliminary research shows that new in vitro bioassays provide an ethical and cost effective alternative ....Saving Nemo: Reducing animal use in toxicity assessments of wastewater. Every day, Australians produce ~5 billion litres of wastewater, which contains a cocktail of chemicals. Industries that discharge wastewater are required to assess chemical risks to the receiving environments by conducting whole animal direct toxicity assessments (DTA), which are expensive and pose an ethical dilemma. Our preliminary research shows that new in vitro bioassays provide an ethical and cost effective alternative that could be incorporated into DTA programs if their ecological relevance can be demonstrated. This project will develop and validate a new and internationally significant suite of in vitro bioassays for incorporation into DTA programs, leading to more ethical, cost effective and improved environmental protection.Read moreRead less

This project aims to understand how different animals encounter pesticide in the landscape through quantifying residue deposition in arid grasslands and investigating how pesticides used to control locust plagues affect fauna. This project will investigate fenitrothion and fipronil, the main pesticides used in Australia for locust control. It will develop a deposition model for aerial pesticide spraying, determine the short-term effect of sprayed pesticides on the behaviour and condition of free-ranging target fauna that use the environment differently, and quantify the relative importance of dietary and non-dietary exposure routes to gauge the importance of animal behaviour on pesticide exposure. Anticipated outcomes are improved baseline assessments for locusticides.Read moreRead less
