ForestPOPs includes two closely related projects: I) Legacy and emerging pollutants in boreal environments and II) POPs in Swedish snow and boreal catchment waters. The projects started in 2013 and ends 2016.
Persistent organic pollutants, POPs, are efficiently distributed through air and can be transported long distances from their source before they re-enter the terrestrial environment. A significant portion of airborne diffuse pollutants ends up in the forest as POPs are attracted to organic carbon and vegetation. This forest filter effect is amplified in cold climates, and boreal forests accumulate therefore large amounts of pollutants. In this project, researchers will find out how mobile the environmental pollutants are in these environments and how the mobility differs for compounds with different physicochemical properties. Does the environmental pollution remain in soil and vegetation until it is degraded, or is it transported away into the streams and lakes and then further out to sea? How do the spring flood and other extreme hydrological situations impact the mobility? How do landscape type, vegetation type and soil properties affect the terrestrial retention?
ForestPOPs is financed by Formas (I) and Oscar and Lili Lamms Minne (I).
Participants from the department are the PhD students Jakob Gustavsson and Minh Anh Nguyen, and the supervisors Karin Wiberg, Martyn Futter, Lutz Ahrens and Sarah Josefsson.
Collaborating partners are the Department of Soil and Environment, The Department of Forest Ecology and Management and Stockholm University.
