Prof. Douglas Evans

Douglas Evans is Professor in Environmental and Resource Studies, Trent University, Canada. Dr. Douglas Evans has been at Trent for over 30 years. His research focuses on the geochemical control of trace metal and radionuclide distribution in the environment, particularly as it relates to the uptake of metals by aquatic organisms. His research interests include: Aquatic toxicology and historical reconstructions of pollution patterns, use of biota such as clams and mussels as accumulators and indicators of pollution; Studies of food chain impacts on aquatic systems of cadmium. lead, mercury. Sediment deposition, bioavailability. Coordinator of major equipment facility for ICP-MS, a multiple element analyzer of great accuracy within tissues and cells.

Dr. Evans' obtained Trent’s first ICP-MS through an NSERC Major Equipment Grant in the early 90s. Since then he has pioneered work in the use of stable isotopes as tracers of geochemical processes. This has included the development of techniques to simultaneously measure competing processes, for eg. uptake and depuration of metals such as Zn and Cd. He has also developed methods for the determination of the binding of trace metals to naturally-occurring ligands such as dissolved organic carbon, methods for measuring biological fractionation of metal isotopes and methods for the rapid measurement of radionuclides.
