Field data indicate that Arctic food webs are remarkably efficient in accumulating persistent organic pollutants. This has major implications for indigenous people health and commercial fishing values. Explanations are searched for in the specific physical environment and ecology of the productive marginal ice zone (MIZ), and include effects of ice-algae micro habitats, transpolar transport of contaminated ice-rafted sediments from Siberian shelves, coincidence in time and space of POP input and shunting of energy into food webs. Extensive field data of POP concentrations and other chemical as well as biological parameters from a number of different physical and biological matrices collected in an Arctic Expedition in 2001, will in combination with advancement of process understanding through lab experiments, return process based predictive models of POP accumulation in Arctic food webs.
