Nitrous oxide and methane emissions from South East Queensland waterways and influence of wastewater discharges. Climate change caused by greenhouse gas emissions is one of the most serious challenges facing mankind. Substantial emission reduction must be achieved, with responsibilities to be shared by all sectors.

Climate change caused by greenhouse gas emissions is one of the most serious challenges facing mankind. Substantial emission reduction must be achieved, with responsibilities to be shared by all sectors. Rivers, estuaries and water storages contribute considerably to global nitrous oxide and methane emissions, much of which is anthropogenic contributed by urban and agricultural run-off and wastewater discharges. Through an in-depth study on several rivers, estuaries and reservoirs in South East Queensland, this project will provide data to enable reliable estimation of such emissions in Australia, and deliver knowledge and tool support for the development of strategic catchment management strategies.Read moreRead less

Fluorinated surfactants and hydrocarbons at coastal airports. Fluorinated surfactants and hydrocarbons at coastal airports. This project aims to develop a model and parameters that describe transport and co-transport of fluoro-surfactants and hydrocarbons, priority pollutants with a wide range of physico-chemical properties, at coastal airports. Sixty percent of Australian airports are in the coastal plain, and all are affected by contamination from internationally banned fluoro-surfactants and ....Fluorinated surfactants and hydrocarbons at coastal airports. Fluorinated surfactants and hydrocarbons at coastal airports. This project aims to develop a model and parameters that describe transport and co-transport of fluoro-surfactants and hydrocarbons, priority pollutants with a wide range of physico-chemical properties, at coastal airports. Sixty percent of Australian airports are in the coastal plain, and all are affected by contamination from internationally banned fluoro-surfactants and hydrocarbons. Their extensive past use at firefighting training grounds resulted in costly remediation worldwide. Understanding the fate of persistent fluoro-surfactants from point sources, and their role in transporting non-polar chemicals such as hydrocarbons, will improve risk-based decision making. This research is expected to form the basis for effective risk management and intervention strategies.Read moreRead less
Formation, degradation and migration of a yet unidentified POP source. Australia has recently ratified the Stockholm Convention, targeting persistent organic pollutants (POPs) for global reduction and elimination. A significant gap exists, however, in understanding sources and pathways of POPs in Australia, and subtropical/tropical environments. Previous research has shown an extensive POP contamination in coastal Australia, and exposure of biota to elevated levels. The present study will evalua ....Formation, degradation and migration of a yet unidentified POP source. Australia has recently ratified the Stockholm Convention, targeting persistent organic pollutants (POPs) for global reduction and elimination. A significant gap exists, however, in understanding sources and pathways of POPs in Australia, and subtropical/tropical environments. Previous research has shown an extensive POP contamination in coastal Australia, and exposure of biota to elevated levels. The present study will evaluate the formation, degradation and migration of POPs, and their significance to Australia's past, present and future emissions. The outcomes will allow identification of sources, their prioritization for elimination and exposure prevention, and ultimately serve to protect the environment and human health in Australia.Read moreRead less
Sources of phosphorus promoting cyanobacteria in subtropical reservoirs. Water managers around Australia are currently considering various strategies to deal with water shortages. Many of these management actions have potential to impact water quality, through altering the nutrient balance within reservoirs and hence affecting nutrients available for cyanobacteria.

Water managers around Australia are currently considering various strategies to deal with water shortages. Many of these management actions have potential to impact water quality, through altering the nutrient balance within reservoirs and hence affecting nutrients available for cyanobacteria. Cyanobacteria blooms pose an increasing threat to water supplies, with economic, social and environmental costs of $150M pa in Australia. The project will provide tools to water quality managers to assess how changes to subtropical reservoirs, such as water recycling, catchment land-use changes and increased drawdown are likely to affect nutrient budgets and cyanobacteria blooms.Read moreRead less

The economic wealth of Australia is underpinned by its remarkable biological diversity. However, land and water degradation are eroding Australia's natural asset base damaging industries such as tourism, fisheries, and forestry. Given limited funds for biodiversity conservation, we need to minimise the misallocation of resources by making wise investments. This research will result in frameworks and tools to ensure that we maximise the protection of biological diversity and the delivery of ecosystem services (such as clean water) that are important for human well-being. We will share the results of our research with decision makers, scientists, and the general public.Read moreRead less
A Fundamental Understanding of Methane Driven Denitrification. Eutrophication in waterways due to the presence of nutrients including nitrogen is a well-recognised environmental problem. Moreton Bay, for example, used to receive 3,300 tons of nitrogen each year from point sources. Stringent nitrogen discharge limits have therefore been imposed on most wastewater treatment systems across Australia. Nitrogen removal from wastewater is commonly accomplished in a biological way involving the use of ....A Fundamental Understanding of Methane Driven Denitrification. Eutrophication in waterways due to the presence of nutrients including nitrogen is a well-recognised environmental problem. Moreton Bay, for example, used to receive 3,300 tons of nitrogen each year from point sources. Stringent nitrogen discharge limits have therefore been imposed on most wastewater treatment systems across Australia. Nitrogen removal from wastewater is commonly accomplished in a biological way involving the use of bacteria. The project aims to investigate a particular bacterial community, which is able to perform nitrogen removal from wastewater with methane as a renewable carbon source. The project will therefore lead to more sustainable wastewater treatment systems.Read moreRead less
