Advanced micro analysis systems for environmental monitoring. Understanding of the behaviour of the nutrients controlling nuisance algae in water bodies is currently limited by the cost and logistics of collecting and analysing the large numbers of samples required.
This proposal describes the development and evaluation of portable multiparameter micro analysis systems that will be capable of high frequency measurements from a sampling vessel. This will enable environmental agencies to perfo ....Advanced micro analysis systems for environmental monitoring. Understanding of the behaviour of the nutrients controlling nuisance algae in water bodies is currently limited by the cost and logistics of collecting and analysing the large numbers of samples required.
This proposal describes the development and evaluation of portable multiparameter micro analysis systems that will be capable of high frequency measurements from a sampling vessel. This will enable environmental agencies to perform rapid on-site mapping of nutrients and other water quality parameters in large water bodies, intensive scale mapping of effluent mixing and dispersal zones, quick assessment of the impact of dredging and aquaculture, and compliance monitoring in effluent streams.

An autonomous microfluidic analyser for the determination of total phosphorus and nitrogen in aquatic systems. Development of automated monitoring systems capable of extended and remote operation will enable assessment of the effectiveness of water treatment and the impact of nutrient releases on the aquatic environment. Both are important in preserving the quality of existing water resources, and assessing the quality of recycled water, in line with the National Research Priority Environmentall ....An autonomous microfluidic analyser for the determination of total phosphorus and nitrogen in aquatic systems. Development of automated monitoring systems capable of extended and remote operation will enable assessment of the effectiveness of water treatment and the impact of nutrient releases on the aquatic environment. Both are important in preserving the quality of existing water resources, and assessing the quality of recycled water, in line with the National Research Priority Environmentally sustainable Australia, and the Priority Goal, Water - a critical resource. Commercialization of the microfluidic flow analysis system for total N and P will enhance the international competitiveness of Ecotech Pty Ltd and Australia as an exporter of scientific instruments.Read moreRead less
Bushfire smoke and the relationship between human and landscape health. A team of landscape ecologists, environmental chemists and public health specialists will determine the ecological causes and adverse health effects of different levels of bushfire smoke in Darwin. Darwin is an ideal setting for this research because the only source of air pollution is the high incidence of controlled and uncontrolled bushfires during the dry season causing variable air quality: a preliminary study found a ....Bushfire smoke and the relationship between human and landscape health. A team of landscape ecologists, environmental chemists and public health specialists will determine the ecological causes and adverse health effects of different levels of bushfire smoke in Darwin. Darwin is an ideal setting for this research because the only source of air pollution is the high incidence of controlled and uncontrolled bushfires during the dry season causing variable air quality: a preliminary study found a link between smoke pollution levels and asthma. The findings of the proposed research will contribute to improved fire management practices to reduce injurious smoke pollution events and contribute to setting appropriate national air quality standards.Read moreRead less
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
Anthropogenic influences on the source, transformation and fate of carbon and nitrogen in coastal waters: a case study of the Derwent Estuary. Ninety five percent of Australia's population live in the coastal zone on the shores of our major bays and estuaries. These water bodies are valuable resources for recreation, boating, fishing, marine transport and industry, but some activities, particularly the release of nitrogen, impose an environmental and economic cost. This project will significant ....Anthropogenic influences on the source, transformation and fate of carbon and nitrogen in coastal waters: a case study of the Derwent Estuary. Ninety five percent of Australia's population live in the coastal zone on the shores of our major bays and estuaries. These water bodies are valuable resources for recreation, boating, fishing, marine transport and industry, but some activities, particularly the release of nitrogen, impose an environmental and economic cost. This project will significantly advance our understanding of the natural processes that control the transformation and fate of nitrogen in coastal waters. As such the outcomes of this study will provide key information for managers on the environmental outcomes of nutrient management strategies.Read moreRead less
Improved electrophoretic analyser for water quality monitoring. This proposal will advance the Australian made Eco Detection portable electrophoretic analyser for autonomous monitoring of water chemistry - the Eco Sensor. We will re-design and miniaturise the fluidic manifold to reduce capital- and per-sample cost, increase the sensitivity of nutrients - nitrate and phospate - by 100-times in both fresh- and sea-waters, and develop new ultra-sensitive reagents for heavy metal detection at enviro ....Improved electrophoretic analyser for water quality monitoring. This proposal will advance the Australian made Eco Detection portable electrophoretic analyser for autonomous monitoring of water chemistry - the Eco Sensor. We will re-design and miniaturise the fluidic manifold to reduce capital- and per-sample cost, increase the sensitivity of nutrients - nitrate and phospate - by 100-times in both fresh- and sea-waters, and develop new ultra-sensitive reagents for heavy metal detection at environmentally regulated levels. This will provide a single platform for at-site near-real-time monitoring of water chemistry for agricultural, mining, water corporations and other industries that use and/or discharge water to the environment.
