No TOF-AMS is currently available in Australia and thus, if acquired, it would significantly enhance Australian research capabilities in a field of high importance for the country and internationally, which is the nature and chemical composition of atmospheric aerosols, their origins and dynamics. The proposed studies with the application of this instrument would greatly increase scientific knowledge of atmospheric particles; would contribute to general welfare and economy in terms of enabling qualitative risk assessment of airborne particles on humans and the environment, and in turn, risk prevention. It would also enable the University partners to continue to produce graduates of high quality, conversant with cutting edge science.Read moreRead less
Physico-chemical Controls on Growth, Toxicity and Succession of Microcystis and Anabaena Species in Sydney Water Supply Reservoirs. Insight into the forms of nutrients that are most readily assimilated by Microcystis and Anabaena species prevalent in Lake Burragorang and other Sydney water supply reservoirs will assist in determining the key drivers to occurrence of blooms of these organisms, particularly when combined with an understanding of the spatial and temporal distribution of the forms o ....Physico-chemical Controls on Growth, Toxicity and Succession of Microcystis and Anabaena Species in Sydney Water Supply Reservoirs. Insight into the forms of nutrients that are most readily assimilated by Microcystis and Anabaena species prevalent in Lake Burragorang and other Sydney water supply reservoirs will assist in determining the key drivers to occurrence of blooms of these organisms, particularly when combined with an understanding of the spatial and temporal distribution of the forms of nutrients, the dynamics of transformation between these various forms and the key parameters of light and temperature. In addition, the particular forms in which nutrients are acquired may influence the extent of toxin production. Thus, the findings of the project will also assist in elucidating the conditions under which toxin generation is expected.Read moreRead less

Recent media attention has highlighted the problem of oestrogenic pollutants in the aquatic environment. This research proposes to investigate Photocatalysis of oestrogens in water using the magnetic titanium dioxide particles developed at the Centre for Particle and Catalyst Technologies in the University of New South Wales, Sydney. The natural oestrogens 17b-oestradiol, oestrone and oestriol and the synthetic oestrogen 17a-ethynyl oestradiol (the main constituent of the contraceptive pill) will be investigated in the photocatalytic system. Degradation will be monitored using various analytical techniques. Other commercial catalysts will also be investigated and compared with the magnetic catalyst and previous catalysts tested.Read moreRead less
Application and evaluation of passive samplers for monitoring aquatic pollution. Pollutants in water bodies pose a threat to environmental and human health. Monitoring of chemicals in water has thus become a key challenge for environmental authorities. Sampling based on the
analysis of grab samples is expensive, complicated and provides only patchy data. Passive sampling devices that allow time integrated sampling of pollutants are a promising alternative.

Monitoring of chemicals in water has thus become a key challenge for environmental authorities. Sampling based on the
analysis of grab samples is expensive, complicated and provides only patchy data. Passive sampling devices that allow time integrated sampling of pollutants are a promising alternative. This collaborative research aims to evaluate a series of existing and novel passive samplers both in laboratory and field conditions and determine sensitive parameters that significantly influence sampler behaviour.
The project should provide a set of new tools for more effective management of water pollution.Read moreRead less
An innovative strategy for stormwater remediation and reduction of contaminant supply from catchments. Many urbanised harbours world-wide are polluted and the main source is stormwater. Currently, emphasis is to remove gross pollutants from stormwater using numerous devices scattered through the catchment.

Many urbanised harbours world-wide are polluted and the main source is stormwater. Currently, emphasis is to remove gross pollutants from stormwater using numerous devices scattered through the catchment. In a radical shift from traditional approaches, we will identify primary contaminant sources in the catchment for later targeted education and regulation and a single remediation device will remove most toxic substances in stormwater currently discharged to estuaries. Stormwater reuse will provide a new valuable urban resource. This paradigm shift in traditional stormwater strategy will ensure biodiversity and ecologically sustainable development of urbanised ports. Port Jackson is used as a test case.Read moreRead less
LARVAL RETENTION AND CONNECTIVITY IN CORAL REEF FISH POPULATIONS: A MULTI-TECHNIQUE APPROACH. A key unanswered question in marine ecology and fisheries management is - are planktonic juveniles retained within or transported among populations? The only three techniques that can potentially quantify larval dispersal distances are genetic markers, natural chemical signatures and applied chemical marks. This project combines, for the first time, all three techniques to measure the scale of disper ....LARVAL RETENTION AND CONNECTIVITY IN CORAL REEF FISH POPULATIONS: A MULTI-TECHNIQUE APPROACH. A key unanswered question in marine ecology and fisheries management is - are planktonic juveniles retained within or transported among populations? The only three techniques that can potentially quantify larval dispersal distances are genetic markers, natural chemical signatures and applied chemical marks. This project combines, for the first time, all three techniques to measure the scale of dispersal in two coral reef fish species. The relative importance of retention and connectivity will be measured, from a large scale encompassing different regions (Great Barrier Reef and Papua New Guinea) to a small scale focussing on individual reefs.Read moreRead less
Metal emissions from petrol and the future health of children. We aim to determine the contribution of manganese, lead, and other metal emissions from motor vehicles to the environment and exposure of
