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

Water reuse is a smart option to reduce primary water consumption, but if it is to be sustainable, fundamental and applied knowledge gaps must be addressed. The proposed sustainable water reuse network enables Australian researchers to engage with end users under an integrated, multi-disciplinary framework. This will allow future research activities to address knowledge gaps and priorities, thereby contributing to a paradigm shift in how Australians use all sources of water and a reframing of our understanding of sustainable water cycles.Read moreRead less
Combining Community Based Social Marketing and Technological Innovation to Combat Wood-Smoke Pollution in Regional Australia. There is considerable evidence to suggest that wood smoke pollution represents a serious health threat. This project will provide valuable information about the relative effectiveness of social marketing and technology-based interventions to reduce wood smoke pollution, and how these interventions may be combined to maximise their impact. The resulting improvements in ai ....Combining Community Based Social Marketing and Technological Innovation to Combat Wood-Smoke Pollution in Regional Australia. There is considerable evidence to suggest that wood smoke pollution represents a serious health threat. This project will provide valuable information about the relative effectiveness of social marketing and technology-based interventions to reduce wood smoke pollution, and how these interventions may be combined to maximise their impact. The resulting improvements in air quality may produce substantial health benefits for the residents of Australian communities that depend heavily on wood as a domestic heating fuel during winter months.

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

It is critical, therefore, to develop rigorous environmental health indicators (EHIs) to provide solid bases for the planning of SD and environmental management decision-making. However, a framework for the development of EHIs has not been attempted. This research aims to increase fundamental knowledge on the relationship between EHIs and SD, to identify a core and extended set of EHIs, and to assess implications of EHIs in the planning of SD and environmental management. A framework for identification and application of EHIs will be developed.Read moreRead less
Phytoremediation of arsenic contaminated sites using arsenic hyperaccumulating plants. The legacy of using arsenical compounds in pest control activities has resulted in many contaminated sites. Since the inorganic arsenic is carcinogenic, stringent laws have been enforced to control arsenic (As) in the environment. This project investigates the potential of using the recently discovered (Ma et al, 2001) arsenic hyperaccumulating (22,000 mgAs/kgDW) fern, Pteris vittata, in the removal of arsen ....Phytoremediation of arsenic contaminated sites using arsenic hyperaccumulating plants.

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
