Legacy and emergent POPs in the Greenland shark Somniosus microcephalus and in its preys from NE Greenland fjords
The Greenland shark Somniosus microcephalus (Bloch and Schneider, 1801) is an interesting species from an ecotoxicologiacl point of view, being a long-lived and slow-growing1 deep-sea shark at risk due to its longevity and food habits that may allow it to bioaccumulate toxic and persistent organic p...
