Is mass commercialisation of silver-based nanotechnology undermining its biomedical antibacterial potential? Silver nanoparticles have demonstrated broad spectrum antibacterial potential and are increasingly used in biomedical applications to limit infection. They are also found in a growing range of everyday products such as shampoos and socks. This situation is analogous to the previous use of antibiotics for nonmedical purposes and the subsequent spread of antibiotic resistant bacteria. This ....Is mass commercialisation of silver-based nanotechnology undermining its biomedical antibacterial potential? Silver nanoparticles have demonstrated broad spectrum antibacterial potential and are increasingly used in biomedical applications to limit infection. They are also found in a growing range of everyday products such as shampoos and socks. This situation is analogous to the previous use of antibiotics for nonmedical purposes and the subsequent spread of antibiotic resistant bacteria. This project will measure silver resistance selection pressure in key microbial communities. Novel monitoring devices, a multi-technique chemistry approach, and correlative synchrotron spectroscopy and molecular biology techniques will be used to decipher the environmental silver resistome and its likely significance.Read moreRead less

Summary
Ecotoxicology-on-a-chip: towards smart devices in environmental biomonitoring. High-throughput water quality monitoring is of great importance to the wellbeing of Australian society. The project will address this issue by developing new economical miniaturised biocybernetic instrumentation, designed for use by non-specialists and thus applicable for governmental, industrial and community projects.
Performance of waste stabilisation ponds: controlling factors, novel performance indicators, and risk assessment. As the world population increases, maintaining robust, cost-effective and environmentally safe wastewater treatment systems is of vital importance. This project will enhance the ability to design, operate and manage Australia's extensive wastewater infrastructure for safer and more sustainable water resources in Australia and the world.
Impact of industrially based endocrine disrupting chemicals on aquatic biota. Endocrine disrupting chemicals (EDCs) are a serious threat to aquatic organisms, livestock and humans. EDCs are present in water discharged from sewage treatment plants and in leachate from contaminated land. This project will determine the impact of EDCs from contaminated landfill on aquatic animals. It will also identify the chemicals responsible for biological impact by developing new bio-assays suitable for industr ....Impact of industrially based endocrine disrupting chemicals on aquatic biota. Endocrine disrupting chemicals (EDCs) are a serious threat to aquatic organisms, livestock and humans. EDCs are present in water discharged from sewage treatment plants and in leachate from contaminated land. This project will determine the impact of EDCs from contaminated landfill on aquatic animals. It will also identify the chemicals responsible for biological impact by developing new bio-assays suitable for industrial, scientific and regulatory authority applications. This research has wide-ranging relevance and value to Australian State and Federal regulators and industries because of the ubiquity of sewage treatment plants and contaminated leachate from landfills.Read moreRead less
Use of effects-based bioassays to assess the endocrine disruption potential of advanced tertiary treated sewage effluent. Water reuse will become a major option to meet increasing water demand in Australia. However, the presence of endocrine disrupting compounds (EDCs) in wastewater has been identified as a potential impediment for this practice. This project will use a combination of effects-based biological methods based on different levels of biological organisation, and chemical analysis to ....Use of effects-based bioassays to assess the endocrine disruption potential of advanced tertiary treated sewage effluent. Water reuse will become a major option to meet increasing water demand in Australia. However, the presence of endocrine disrupting compounds (EDCs) in wastewater has been identified as a potential impediment for this practice. This project will use a combination of effects-based biological methods based on different levels of biological organisation, and chemical analysis to assess the efficacy of an advanced tertiary sewage treatment plant (ATSTP) to remove EDCs. The results will provide insights on 1. effects of mixtures of EDCs; 2. characterisation of risks of reuse of treated effluent; 3. optimisation of effluent treatment technologies to ensure industry competitiveness; and 4. developing sustainable plans to meet future water demand.Read moreRead less

Diagnosing river health using invertebrate traits and DNA barcodes. This project aims to develop indices that link change in invertebrate communities to specific environmental stressors, and combine these indices with innovative, low cost molecular approaches to species identification to rapidly identify the causes of decline. River health assessment methods, usually based on aquatic invertebrates, identify if rivers are impaired but must be developed to identify the causes of decline. The intended outcomes are improved sustainable water resource management within and among states, and improved natural resource policy development.Read moreRead less
Quantitative metrics for determining aquifer ecosystem state. Clean groundwater comes from dirty surface water by way of biological purification. This project will develop quantitative ways to assess groundwater ecosystems to ensure the sustainable extraction of water and maintenance of these crucial ecosystems.
The Effect of Fuel Type on Health and Environmental Risks Caused by Motor Vehicle Emissions. Motor vehicles constitute one of the most significant sources of air pollutants but the state of knowledge on the quantity of some of these does not permit for projection of the risk they create. This project aims at quantification of emissions of pollutants contributing to deterioration of health, ozone formation, global warming and acid rain as a function of fuel type, using a novel on-road sampling m ....The Effect of Fuel Type on Health and Environmental Risks Caused by Motor Vehicle Emissions.
