Trace Metals in Mesozooplankton of the North Sea: Concentrations in Different Taxa and Preliminary Results on Bioaccumulation in Copepod Collectives ( Calanus finmarchicus/C. helgolandicus)
Abstract Trace metals (Cd, Cu, Zp, Pb, Ni) were determined in different zooplankton taxa to assess their role in the biogeochemical cycle in the North Sea. Results of semi‐static bioaccumulation experiments on board ship using collectives of Calanus finmarchicus/C. helgolandicus were in agreement wi...
