This study investigates the use ofthe in situ passive sampling technique of diffusive gradients in thin films (DGT) to measure trace metal contaminants in overlying water and sediment porewater adjacent to a waste disposal site at the year-round Australian Antarctic research base, Casey Station. Marine sediment in a bay adjacent to the waste disposal site has been previously identified as having elevated levels oftrace metals, in particular Cd, Pb, Sn, Cu and Zn. Further development of the DGT technique was investigated with the application and testing of a new paper-based DGT sampler.
