Promotional Information

An essential guide to the applications and usage of the diffusive gradients in thin-films (DGT) technique for students and professionals.

About the Author

William Davison is Emeritus Professor of Environmental Chemistry at Lancaster Environment Centre, Lancaster University, UK, where he has previously served as Head of Department. His studies, complemented by research in environmental analytical chemistry, focus on the biogeochemistry of carbon, iron, manganese, sulphur and trace metals in natural waters. Professor Davison, with his colleague Hao Zhang, developed the techniques of diffusive equilibration in thin-films (DET) and diffusive gradients in thin-films (DGT) and pioneered their initial applications in waters, soils and sediments. He has contributed to over 250 publications, and the applications of his work have been recognised by the Pollution Abatement Technology Awards and the RSC Sustainable Water Award.

Reviews

'For the first time, a complete single information source is available that covers the whole DGT concept, covering both the principal mechanisms and the whole range of application possibilities. Everyone who is interested in starting or continuing DGT work will find a comprehensive and detailed compilation of the current DGT knowledge. The publication of this book is a milestone in agricultural and environmental chemistry and will further boost the application of DGT and the further development of DGT application approaches.'
