Title: Using stable isotope tracers to measure transfer of mercury among organs in mammals

Speaker: Douglas Evans（Trent University, Canada）

Moderator: Prof.GAO Yuxi

Time: 10:00, June 25

Place: Room C305, IHEP Main Building

Abstract:

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.

Dr. Evans obtained Trent’s first ICP-MS through a 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. In this talk he will introduce the development of techniques to simultaneously measure competing processes, for e.g. 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.
