Processes and Fluxes of Contaminants in Aquatic Systems
Principal Investigator: Gregor, Dennis J.
Licensed Year(s): 1993
Summary: Atmospheric contaminants that accumulate in the snow are released during a very short time in the spring when the snow melts and washes out through rivers and lakes into the Arctic Ocean. Contaminants can be bound to substrates, consumed by organisms or transformed so that not all contaminants deposited in the snow reach the Arctic Ocean. In this on-going study, contaminant levels and distributi...


Trace Organic Contaminants in Arctic Snow and Aquatic Ecosystems
Principal Investigator: Gregor, Dennis J.
Licensed Year(s): 1992 1991 1991 1990
Summary: Snow samples will be collected from approximately 30 sites across the NWT and Yukon in the spring of the year. This annual snow pack sample will allow an estimate of the quantity of organic contaminants that have been deposited over the winter season. To better understand the fate of these contaminants in the High Arctic, the researchers will undertake an intensive small basin study on Cornwallis ...
