Emissions and pathways of organic contaminants

Differing pathways for contaminants carried with surface (blue) ande mid-depth (red) water masses in
the Arctic Ocean (red circle) have to be taken into account and should be reproduced by models. Source: WHO

Model simulations of organic contaminants

Several different models have been used within the ArcRisk project to explore how climate variability and global climate change affects the routes and mechanisms by which pollutants are delivered to the Arctic, a suite of models have been applied (including multimedia models and single-media atmospheric and oceanic transport models). Information about the models can be found here. The results of the model simulations using the different models for the selected organic substances are summarised in the different substances: (also find in the menu to the right)
