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.
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.
Disinfection by-products formed during drinking water treatment: reducing the unknowns is managing risk. Disinfection of drinking water is a successful measure to reduce water-borne diseases and protect health. However, epidemiological evidence links bladder cancer to disinfection by-products formed during drinking water treatment. Despite decades of research the causative agents remain to be identified. To fill this knowledge gap, this project will quantify the fraction of toxicity that cannot ....Disinfection by-products formed during drinking water treatment: reducing the unknowns is managing risk. Disinfection of drinking water is a successful measure to reduce water-borne diseases and protect health. However, epidemiological evidence links bladder cancer to disinfection by-products formed during drinking water treatment. Despite decades of research the causative agents remain to be identified. To fill this knowledge gap, this project will quantify the fraction of toxicity that cannot be explained by known chemicals in water samples treated with different disinfectants using a combination of chemical analysis and in-vitro bioassays. Samples with high unexplained effects will then be fractionated to isolate toxicologically relevant disinfection by-products, which will ultimately be identified with non-target chemical analysis.Read moreRead less
Estimating use of tobacco and nicotine products through wastewater analysis. This project aims to equip the Australian public health and security sector with a tool to accurately measure tobacco consumption in the general population. Specific human biomarkers in urine will be identified using non-target approaches and their pharmacokinetics quantified. The new data will address critical gaps in our knowledge on the population-level excretion of biomarkers for the consumption of tobacco and alter ....Estimating use of tobacco and nicotine products through wastewater analysis. This project aims to equip the Australian public health and security sector with a tool to accurately measure tobacco consumption in the general population. Specific human biomarkers in urine will be identified using non-target approaches and their pharmacokinetics quantified. The new data will address critical gaps in our knowledge on the population-level excretion of biomarkers for the consumption of tobacco and alternative nicotine products. The outcomes of this project will provide reliable, cost-effective estimates of tobacco consumption for use with wastewater-based epidemiology assessments. This will enable changes in tobacco use to be accurately evaluated for the first time and improve the efficacy of tobacco control measures.Read moreRead less
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
