Arsenic Intake from Multiple Exposure Routes in the UK – Methods, Implications and Recommendations for Regulation
David Polya is Professor of Environmental Geochemistry in the School of Earth and Environmental Sciences (SEES) at the University of Manchester (UoM). Previous employment/visiting researcher positions included with the Tasmanian Mines Department (now Mineral Resources Tasmania) (Australia), Monash University (Australia), the Oak Ridge National Laboratory (USA) and GeoScience Limited (UK). He has over 30 years’ experience of research on the (bio)geochemical behaviour of metals and metalloids in surface and sub-surface systems, and involving field, laboratory, spectroscopic and computer modelling approaches. The research, output to date in over 90 publications in international journals, including “Nature” and “Nature Geoscience“, has applications to exploration for mineral deposits, improved petroleum and geothermal reservoir production, geological disposal of radioactive and other wastes, and particularly to the prediction and risk assessment of the occurrence of arsenic and other contaminants in well waters and soils. The research / training / knowledge transfer has been funded (> £10M; with >£5M as PI) by the European Commission, NERC, EPSRC, TSB (now Innovate UK) and the British Council as well as contributions from commercial and/or regulatory organisations in the instrumentation, mining, water and environmental sectors.
Current research includes (i) assessing human health risks arising from widespread arsenic contamination of rice and drinking water supplies; and (ii) using stable and radiogenic isotopic tracers and spectroscopic (XAS) methods to test hypotheses that massive groundwater exploitation in densely populated circum-Himalayan river basins is causing long-term secular increases in groundwater arsenic hazard.
He has coordinated pan-European (AquaTRAIN Marie Curie Research Training Network), Europe-Asian (EU ASIA-LINK CALIBRE) and UK-India (UKIERI PRAMA) research/research training programmes and is a former School Director of Postgraduate Research. Professor Polya has coordinated networking activities largely within UoM in relation to water-related research, to research in the nexus between water, food & energy, and more widely in environmental research. He is co-editor of the recently published Interrnational Water Association (IWA) “Best Practice Guide on the Control of Arsenic in Drinking Water”.
