Smelter slag containing copper and other trace elements is widespread in riverbed sediment of the upper Columbia River (UCR) of the United States. To evaluate potential risk to aquatic life concentrations of copper and other trace elements were measured in shallow pore-water and in river water samples collected near the sediment-water interface. Samples were collected using an in-situ pore-water profiler to collect a suite of four water samples from above, at, and below the sediment-water...
