11:00 AM - 12:30 PM
Professor Michael Warne works at the Centre for Agroecology, Water and Resilience at the University of Coventry and the University of Queensland, Australia. He conducts research on the transport, fate and effects of pollutants on aquatic ecosystems. Currently his work focusses on the effects of pesticides on aquatic ecosystems and developing guidance to permit farmers to choose less environmentally harmful pesticides.
The seminar will present findings from recent publications and current projects. These include:
- The development of simple relationships between land use and pesticide mixture toxicity and using these to predict the risk posed by pesticides at 170 catchments of the Great Barrier Reef (GBR);
- a detailed examination of the risk pesticides pose;
- trends in the aqueous concentration and risk posed by imidacloprid (an insecticide recently banned from outside use in the EU);
- interactions of pesticides with other stressors including temperature and suspended solids and finally;
- the support tool developed to provide guidance to farmers and other stakeholders in the pesticide industry to enable them to choose less harmful pesticides.
