Tropical aquatic ecotoxicology

The SSD Ecotoxicology program investigates the risks and impacts of contaminants to the highly-valued freshwater ecosystems in the wet-dry monsoonal tropics of northern Australia. The Ecotoxicology Laboratory, located at the SSD laboratory complex in Darwin, is a purpose-built, state-of-the-art facility designed for the conduct of high quality ecotoxicological assessments.
Ecotoxicological tests are usually carried out in the laboratory, and measure the response of individuals of a species to a single chemical or complex mixture (eg a mine waste water). The results are used to predict levels of contaminants that will cause (i) minimal harm to the aquatic environment, or (ii) the actual harm being caused by contaminants already in the environment. Ecotoxicological data are often compared with environmental exposure data in order to predict ecological risk.
Toxicity test procedures that follow fully developed and documented protocols are carried out using a range of aquatic species representative of many freshwater ecosystems across the wet-dry tropics of Australia and south-east Asia. The organisms are cultured and reared in aquaculture facilities or in the laboratory.
Ecotoxicological research at SSD is focused on risk assessment of chemical threats such as mine waters and their associated heavy metals (eg uranium, copper, cadmium, aluminium), and pesticides used for agriculture and the control of wetland weeds.
