Transport and occurrence of new organic contaminants in the Arctic

0
Circumstances have been described where concentrations of contaminants have been higher in remote regions than in source regions. Examples are elevated concentrations of persistent organic pollutants (POPs) in Arctic and high mountain regions.

POPs are organic chemicals known to be toxic, bio-accumulative, persistent and susceptible to long-range transport (LRT).

Due to their potential harmful properties, international agreements are now coming into effect to reduce further environmental exposure of such substances.

In order to provide scientific support for these conventions in identifying chemicals of concern, it is thus important to improve and evaluate criteria or models for identifying chemicals with a potential for LRT.

NILU is currently involved in studies aimed to improve the understanding of the LRT behaviour of POPs and related chemicals of emerging concern through further development of LRT-based multimedia models.
