Body residues as dose for sublethal responses in alevins of landlocked salmon ( Salmo salar m. sebago ): A direct calorimetry study
Abstract Qestions of organism‐specific factors, toxicity endpoints, and their relation to mode‐of‐action all are related to consistency and applicability of body residue‐based approaches. To address this issue, direct calorimetry was used to evaluate metabolic responses of alevins of landlocked salm...

Abstract Qestions of organism‐specific factors, toxicity endpoints, and their relation to mode‐of‐action all are related to consistency and applicability of body residue‐based approaches.
