Tom Cresswell

Dr Tom Cresswell

Isotope Ecologist

Role at ANSTO

Tom is a research scientist focused on the use of radioactive isotopes as tracers of pollution within the aquatic environment. Areas of study include metal and radionuclide bioaccumulation by freshwater invertebrates, the impacts of mining on aquatic ecosystems and the physiological processes of metal and radionuclide regulation by aquatic organisms. Tom also uses autoradiography at the conclusion of exposures to determine the localisation of bioaccumulated metals within the organism. Tom has previously conducted radioisotope tracer studies using freshwater snails to determine the bioaccumulation of nano particles vs. bulk particles via ingestion. Currently studying the bioaccumulation, internal distribution and resultant organ-specific doses of radio Cs and Sr in a mangrove crab to investigate the local impacts of the Fukushima nuclear power plant accident. Research into microplastics as vectors of contaminant bioaccumulation by marine organisms is also ongoing.
