In Australia, there is high community concern around inadvertent exposure to methamphetamine residues in contaminated houses. In this proposal, an interdisciplinary research team aim to engage with public health authorities and public housing industry to conduct collaborative research on total exposure to methamphetamine in contaminated indoor environments. The project will assess exposure pathways (via air, dust, surfaces) and link them with methamphetamine levels in samples from occupants (urine, hair). The project is expected to significantly enhance our understanding of how third hand exposure leads to internal exposure in humans. This knowledge provides evidence for policies on residential indoor exposures and remediation strategies.Read moreRead less

Freshwater streams are disproportionately large producers of greenhouse gases. Identifying the factors controlling their greenhouse gas production is critical as stream function is increasingly altered by both changing rainfall patterns and human pollution. This project aims to resolve the factors controlling stream greenhouse gas production. It will apply an unprecedented combination of continuous stream function and intensive isotope measurements to perennially flowing and intermittent streams in disturbed and undisturbed landscapes. This project is significant because it will quantify the changing role of streams in greenhouse gas emissions. Outcomes will provide critical information for managing Australia’s freshwater resources. Read moreRead less
Finding lost dust storms: re-evaluation of the last 20 years of meteorological records to advance wind erosion mapping in Australia. The Dust Event Database (DEDB) at Griffith University is the only long term (1960 - present) record of wind erosion in Australia. It is used in many studies of the impact of dust on the terrestrial, atmospheric and marine environments as well as in studies of urban and regional air pollution and environmental health. Through this project, the revision of the DEDB w ....Finding lost dust storms: re-evaluation of the last 20 years of meteorological records to advance wind erosion mapping in Australia. The Dust Event Database (DEDB) at Griffith University is the only long term (1960 - present) record of wind erosion in Australia. It is used in many studies of the impact of dust on the terrestrial, atmospheric and marine environments as well as in studies of urban and regional air pollution and environmental health. Through this project, the revision of the DEDB will provide new knowledge on these impacts of wind erosion processes and will inform environmental policy through its contributions to the Caring for Our Country Program, the national State of the Environment, and the Australian Centre for Rangeland Information Systems.Read moreRead less
Australian coastal observation network: monitoring and forecasting coastal erosion in a changing climate. Australia's coastline is one of this country's greatest natural, economic and cultural resources. The asset value of existing beach-front infrastructure is immeasurable.

Australia's coastline is one of this country's greatest natural, economic and cultural resources. The asset value of existing beach-front infrastructure is immeasurable. Climate change is driving sea-level rise and changing regional wave climates, resulting in coastal erosion and increasing the threat to coastal sustainability. This research launches a strategic university-industry-government alliance to address the considerable and growing pressure for solutions to observe and forecast accelerating shoreline erosion. The new knowledge, greater cross-sector collaboration and international linkages to be fast-tracked by this project will inform and build the capacity of Australia's coastal managers to confront the challenges of a changing climate.Read moreRead less
How effective are environmental flows? Novel approaches for monitoring and assessing ecological responses to large-scale flow alteration. Australia has begun a multi-billion dollar program to return water to stressed rivers as environmental flows. However, during times of unprecedented water scarcity, such an investment in the environment can be controversial because the ecological benefits of released water are mostly poorly understood. This project will demonstrate the effectiveness of environ ....How effective are environmental flows? Novel approaches for monitoring and assessing ecological responses to large-scale flow alteration. Australia has begun a multi-billion dollar program to return water to stressed rivers as environmental flows. However, during times of unprecedented water scarcity, such an investment in the environment can be controversial because the ecological benefits of released water are mostly poorly understood. This project will demonstrate the effectiveness of environmental flows, and promote greater understanding of the links between flow patterns and river health. The project will build upon existing knowledge to create a sound framework for planning, monitoring, and evaluation of environmental watering decisions across regional Australia, greatly improving our ability to sustainably manage rivers into the future.Read moreRead less

Poor water quality affects many rivers and receiving waters such as the Great Barrier Reef and Gippsland Lakes. This project aims to use Bayesian hierarchical models of statewide water quality data to quantify the effects of a range of factors on stream water quality including climate, land use, river flow, vegetation cover, etcetera. The analysis intends to extract information from the entire data set rather than concentrating on individual sites. It intends to underpin a new predictive capacity including response to land use and management changes and climatic variations based on long-term data sets, as well as a water quality prediction capability. It is intended that the models developed will jointly model a range of inter-related water quality parameters.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
