Contaminant and Biological Data on Landlocked Arctic Char

The purpose of this study is to examine trends over time of mercury and other trace elements, as well as legacy and new persistent organic pollutants (POPs) in landlocked Arctic char collected annually from lakes near the community of Resolute Bay on Cornwallis Island (Amituk, Char, North, Small, and Resolute) and in Lake Hazen in Quttinirpaaq National Park on Ellesmere Island. The project is also examining links between climate warming and increases or decreases in mercury concentrations in landlocked char. The project has included several graduate student led side projects (see (i) Gantner, N et al. (2009): Temporal trends of mercury, cesium, potassium, selenium, and thallium in Arctic char (Salvelinus alpinus) from Lake Hazen, Nunavut, Canada: effects of trophic position, size, and age.
