Estimating per capita use and release of chemicals by wastewater analysis. This project aims to systematically collect and analyse wastewater to assess human exposure to chemicals including drugs, pharmaceuticals, lifestyle chemicals and environmental pollutants. By combining temporal sampling from key sewage treatment plants with comprehensive nationwide sampling over the week of the 2016 census day, the project expects to estimate the per-capita human exposure to chemicals in the Australian po ....Estimating per capita use and release of chemicals by wastewater analysis. This project aims to systematically collect and analyse wastewater to assess human exposure to chemicals including drugs, pharmaceuticals, lifestyle chemicals and environmental pollutants. By combining temporal sampling from key sewage treatment plants with comprehensive nationwide sampling over the week of the 2016 census day, the project expects to estimate the per-capita human exposure to chemicals in the Australian population. Accurate and objective per-capita based consumption and release estimates for a wide range of chemicals is intended to provide a baseline against which to measure changes in our chemosphere.Read moreRead less
Impact of natural organic matter and nutrients on water quality: identification of catchment sources and attenuation processes.

The outcomes of this project will provide water and catchment managers with a technology that significantly secures the supply of resources for high quality drinking water.
Understanding Australia by analysing wastewater during the Census 2021 . This project aims to utilise the Australian Census 2021, a unique opportunity to link exposure to chemical and biological hazards with catchment socio-demographic data via systematic wastewater analysis. The project is expected to advance our capabilities to identify emerging hazards and understand factors that affect spatiotemporal trends in hazards across Australia. Moreover, in a world first, the project aims to assess c ....Understanding Australia by analysing wastewater during the Census 2021 . This project aims to utilise the Australian Census 2021, a unique opportunity to link exposure to chemical and biological hazards with catchment socio-demographic data via systematic wastewater analysis. The project is expected to advance our capabilities to identify emerging hazards and understand factors that affect spatiotemporal trends in hazards across Australia. Moreover, in a world first, the project aims to assess chemical fate on a national level by linking sales/use with fate and release from wastewater treatment plants and assess treatment efficiency at >100 plants around Australia. The project expects to provide insight for government, wastewater managers and industry into hazards that may affect environmental and human health.Read moreRead less
Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia ....Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia from invasive diseases. There is an urgency to undertake our research because global environmental change and increasing movements of people (particularly military personnel) from overseas regions where these diseases are endemic is increasing the vulnerability of northern Australia to the (re)establishment of mosquito borne diseases.Read moreRead less

A surface functionality based approach for the risk assessment of manufactured nanomaterials in the environment. Manufactured nanoparticles are increasingly present in the environment yet their risk assessment is fraught with analytical challenges. This project will use customised nanoparticles with unique isotopic signatures and surface properties to circumvent key difficulties and support novel investigations into nanoparticle stability, fate and toxicity.
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
Addressing the uncertainties: Pathways, fate and associated risks of manufactured nanoparticles in the environment. Manufactured nanomaterials are increasingly present in commercial products, such as sunscreens, textiles and building materials. Their subsequent release to the environment is unavoidable. This project will deliver novel methods for assessing the associated risks, thereby supporting the safe and sustainable use of nanomaterials in Australia.
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
