Research interests include the processes that control the behaviour and toxicity of trace elements such as arsenic, copper, lead, zinc and cadmium in natural freshwaters and groundwaters. This includes waters affected by acid mine drainage, urban stormwater and geothermal fluid discharge, the role of natural iron oxide minerals in reducing trace element toxicity and mobility in freshwaters, and trace element and major ion behaviour in Antarctic meltwaters, particularly the lake and pond systems which accommodate most of Antarctica’s inland biological communities. Field, analytical and experimental approaches are used, together with computer modelling of metal speciation, toxicity and adsorption processes in aquatic systems.
