Predictive Modelling of Vanadium Cycling, Speciation and Bioavailability in Contrasting Scottish and Chinese Lake Sediments
Vanadium (V), a trace element in coal and oil, is released into the atmosphere by fossil fuel combustion. A proportion will subsequently be deposited in aquatic sediments but it is also released directly into aquatic systems as a consequence of several industrial processes, e.g. leachates from oil sands in Canada, from vanadium-titano-magnetite mining in China, from uranyl vanadate(carnotite) mining in the US and from Red Mud spillages in the UK and Hungary, and from application of certain fertilisers. Although reportedly toxic to aquatic biota, little is known about the biogeochemical behaviour of vanadium. Our on-going research has shown V release from contaminated loch sediments is complicated and controlled by multiple factors, including ion concentration, pH and redox conditions.
