Environmental Distribution Processes of Persistent Organic Pollutants in Polar Regions
Global atmospheric transport has led to the dispersal of many Persistent Organic Pollutants (POPs) generated at lower latitudes, allowing them to reach Polar latitudes. Although the ice has long been considered simply as a means of immobilising these toxic chemicals, it is in fact an annual source t...

Global atmospheric transport has led to the dispersal of many Persistent Organic Pollutants (POPs) generated at lower latitudes, allowing them to reach Polar latitudes.

This results in pulse exposure to Polar biota during summer periods of high marine productivity.
