Preliminary studies on heavy metal contents in aquatic organisms from the Hornsund area, with a particular reference to the Arctic charr (Salvelinus alpinus (L.))
Contents of Hg, Cd, Pb, Cu, and Zn were determined in the wreck bladder, barnacles, gammarids, euphausiids, and the Arctic charr collected in the Hornsund area in 1985-1986. Mercury was determined with CV AAS, while the remaining metals were studied with FAAS. Mercury levels were found to increase u...
