Atmospheric transport of organic contaminants
Principal Investigator: Waite, Don
Licenced Year(s): 1993
Summary: In this study, we will collect air, dust and rain samples on a weekly basis at five Canadian locations during the months of June and July, 1993. Three locations are in the NWT while two locations are in Saskatchewan. The samples will be analyzed in Regina and Edmonton for the presence of certain insecticides, herbicides and PCB's that are known to be transported in the atmosphere....


Current contaminant deposition measurements in precipitation throughout the NWT
Principal Investigator: Gregor, Dennis J.
Licenced Year(s): 1993
Summary: Contaminants are carried in the air to the arctic during the winter when large-scale wind movements bring these contaminants from industrialized locations in North America, Europe and Asia to the north. Snow can collect these compounds from the air and bring them to the ground where they can accumulate. Thus, it is important to study the amount of contaminants in snow to determine the types and ...
