SHOTYK, William -Department of Renewable Resources, University of Alberta
Dr. Shotyk has pioneered the use of peat bogs to decipher the global history of metal pollution and environmental changes during the last 15,000 years. His painstaking measurements of the concentrations of lead and its isotopes as well as other metals in dated peat cores and ice layers deposited during the Post-Glacial period currently represent an international reference against which other studies on metal paleo-pollution are calibrated.
