Summary
Global Influence of Intraseasonal Variability in Ozonesonde Profiles. This proposal aims to better understand how tropical intraseasonal variability (periods of 40 to 60 days) influences the chemical components of the global atmosphere. The results of the research aim to improve regional air-quality forecasts on weekly and monthly timescales. The highly vertically resolved ozone concentrations from the surface up to 20 kilometres, measured by balloon-borne instruments called ozonesondes, will be ....Global Influence of Intraseasonal Variability in Ozonesonde Profiles. This proposal aims to better understand how tropical intraseasonal variability (periods of 40 to 60 days) influences the chemical components of the global atmosphere. The results of the research aim to improve regional air-quality forecasts on weekly and monthly timescales. The highly vertically resolved ozone concentrations from the surface up to 20 kilometres, measured by balloon-borne instruments called ozonesondes, will be used as a dynamical tracer. The knowledge gained from the ozonesonde data will be used to elucidate the chemical origins of the tropical variability related to biomass burning activities and convective lightning, as well as the subtropical variability related to the polar vortex dynamics.Read moreRead less
Understanding and controlling bioavailability: passive dosing of persistent organic pollutants into recombinant cell bioassays. Bioassays with mammalian cell lines may replace animal testing in chemical risk assessment if issues with limited sensitivity can be overcome for very hydrophobic chemicals such as polychlorinated dibenzodioxins. The project will solve this problem by developing a polymer-release dosing technique that assures defined and constant exposure.
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
A novel path to environmental and human health risk assessment of transformation products. Chemical pollution is a threat to our rivers and drinking water supplies. Degradation during water treatment and in the environment may lead to persistent and toxic transformation products. This project will provide a practical and cost-efficient risk assessment strategy for transformation products - to help ensure that our drinking water is safe.
Investigation of endocrine disruption in Australian aquatic environments. Water is a vital resource. The disposal of wastes is often associated with the release of contaminants like endocrine disruptors into the environment. These contaminants can impact the health of our waterways and lead to potential risks to fish populations and ultimately public health. The hazards resulting from endocrine disruptors have been well defined globally and to a lesser extent in Australia in the last decade, how ....Investigation of endocrine disruption in Australian aquatic environments. Water is a vital resource. The disposal of wastes is often associated with the release of contaminants like endocrine disruptors into the environment. These contaminants can impact the health of our waterways and lead to potential risks to fish populations and ultimately public health. The hazards resulting from endocrine disruptors have been well defined globally and to a lesser extent in Australia in the last decade, however we have very limited information about possible effects in Australian waterways or reservoirs. This research project will investigate the state of endocrine disruption in our waters. The knowledge gained will address this gap and provide a benefit to the national community, risk managers and importantly our waterways.Read moreRead less
Exposure mapping - combining wastewater analysis with human biomonitoring. This project aims to develop a spatial and temporal understanding of chemical exposure in the Australian population. The project will use wastewater samples collected from over 100 catchments (65% of Australian population) during the 2016 Census to spatially resolve human exposure to chemicals. These data will then form the basis for focused human biomonitoring using pooled surplus pathology samples. The integration of ....Exposure mapping - combining wastewater analysis with human biomonitoring.

These data will then form the basis for focused human biomonitoring using pooled surplus pathology samples. The integration of wastewater and biomonitoring data will allow the creation of a national hazard specific exposure map that can be compared with geospatial data on disease risk and socioeconomic indicators (via ABS information). The benefits include the capability to identify and manage exposure risks to public health.Read moreRead less
Understanding changes in chemical exposure through integrative sampling and systematic archiving. Poor data on exposure limits our understanding of the effects of chemical exposure on health. This project will aim to develop population-based exposure monitoring strategies to measure exposure, exposure trends, the success of intervention strategies and associations between exposure and health outcomes.
Fate of micropollutants in water recycling: influence of dissolved organic matter. Access to safe drinking water is essential for the economic and social development of Australia. There is increasing interest in applying advanced water treatment processes, such as membrane filtration or ozonation, to treat secondary effluent to a potable standard. This project promotes improved organic pollutant removal and monitoring during advanced water treatment and will contribute to the National Research P ....Fate of micropollutants in water recycling: influence of dissolved organic matter. Access to safe drinking water is essential for the economic and social development of Australia. There is increasing interest in applying advanced water treatment processes, such as membrane filtration or ozonation, to treat secondary effluent to a potable standard. This project promotes improved organic pollutant removal and monitoring during advanced water treatment and will contribute to the National Research Priority goal, water - a critical resource, by providing the increased protection of receiving waters including rivers and seawater. Further, as very few studies consider the role of dissolved organic matter for organic pollutant fate in water reuse internationally, this project will help to advance Australia's position in science.Read moreRead less

A coupled liquid chromatography mass spectrometer as a core component of an Australian research facility for marine microbial biotoxins: This project will establish an Australian research facility for marine microbial biotoxins. The requested core instrument is a liquid chromatography mass spectrometer to analyse and quantify microbial toxins at ultra-trace quantities against complex sample backgrounds. Specialists in diverse areas of marine ecology and chemistry from three partner universities will team up to focus their research on novel biotoxins and marine natural products. This research is significant in developing a capability to swiftly respond to the emergence and outbreak of novel toxins. This facility will foster the collaboration with the partner organisation, the Cawthron Institute, a world leading research institute of marine biotoxins.Read moreRead less
