Using a battery of tests to evaluate the potential toxicity of remediated and unremediated soils and dusts contaminated with metals. An in vitro model simulating the intact and immature infant intestinal epithelium will be used to determine the changes in solubility and uptake of metals following in situ remediation processes. The earthworm and bacterial luminescence toxicity tests indicate the ecotoxicity of contaminated soils.

An in vitro model simulating the intact and immature infant intestinal epithelium will be used to determine the changes in solubility and uptake of metals following in situ remediation processes. The earthworm and bacterial luminescence toxicity tests indicate the ecotoxicity of contaminated soils.
Many garden soils, household dusts, and industrial sites are contaminated with lead, cadmium, and other metals. These pose a risk to human health, especially of children, and ecosystem health
These tests will be applied to prioritise sites where metal contamination exists and to evaluate the effectiveness of remediation techniques in reducing metal uptake and toxicity.Read moreRead less
Assessment of bentonites as remediating agents for metal contaminated soils using innovative bioavailability reduction technology. The project seeks to carry out research on innovative, economically sustainable risk-based solutions (soil amendments) for metal-contaminated soils and methods for assessing the potential risk/bioavailability of soil bound metals. The work will determine factors affecting the reactivity, mobility and bioavailability of metals in Australian soils and clays and method ....Assessment of bentonites as remediating agents for metal contaminated soils using innovative bioavailability reduction technology. The project seeks to carry out research on innovative, economically sustainable risk-based solutions (soil amendments) for metal-contaminated soils and methods for assessing the potential risk/bioavailability of soil bound metals. The work will determine factors affecting the reactivity, mobility and bioavailability of metals in Australian soils and clays and methods by which these can be controlled. Remediation options, such as natural clay amendments to reduce metal bioavailability, will be assessed against in vivo and in vitro bioavailability assays in order to develop cost effective, risk-based remediation strategies and assessment protocols for urban and rural contaminated soils.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
