An in situ study on the distribution, biotransformation and flux of polycyclic aromatic hydrocarbons (pahs) in an aquatic food chain (seston‐ Mytilus edulis L.‐ Somateria mollissima L.) from the baltic: An ecotoxicological perspective
Abstract This in situ study is focusing on the distribution, biotransformation and flux of 19 polycyclic aromatic hydrocarbons (PAH 19 ) in the food chain seston‐blue mussel ( Mytilus edulis L.)‐common eider duck ( Somateria mollissiima L.) as well as the distribution in the gallbladder, liver, adip...
