Previously, high concentrations of cadmium have been found in the hepatopancreas of the edible or brown crab (Cancer pagurus) sampled from positions north of about 67° N, compared to regions further south along the Norwegian ...
Facilitating microplastic quantification through the introduction of a cellulose dissolution step prior to oxidation: Proof-of-concept and demonstration using diverse samples from the Inner Oslofjord, Norway

Olsen, Linn Merethe Brekke; Knutsen, Heidi; Mahat, Sabnam; Wade, Emma Jane; Arp, Hans Peter (Journal article; Peer reviewed, 2020)

Identifying and quantifying microplastic in marine samples can be facilitated by removing natural organic matter (NOM). Cellulosic material, like chitin, however, are a type of NOM that is resistant to chemical digestion, ...

Knutsen, Heidi (Master thesis, 2017-04-28)

I taskekrabbe (Cancer pagurus) langs norskekysten er det målt høye konsentrasjoner av miljøgiften kadmium, med betydelig høyere nivåer i Nord- sammenliknet med Sør-Norge. Den klare nord-sør gradienten i taskekrabbens ...
