Includes bibliographical references (page 48). "Long-range transport of air pollutants (or LRTAP) is the mechanism by which atmospheric contaminants are transported very long distances to be deposited and affect the environment thousands of kilometers away from the source of the emissions. From investigation of lake sediments, chemical species are known to be transported into the river basins of northern Alberta via atmospheric pathways. The Atmospheric Environment Service (AES) Lagrangian back trajectory model was used to identify the potential atmospheric routes for airborne contaminants to the basin"--Report summary.
