Trace metals in cod from the southern Baltic, 1983

The cadmium, lead, copper, zinc, iron, manganese, and nickel concentrations have been determined in muscle tissue of 201 cod (Gadus morhua) netted in 1983 in different regions in the southern part of the Baltic Sea. The method of measurement was atomic absorption spectrophotometry. The mean values obtained related to wet weight (mg/kg) for cod muscle tissue were: 0.005 Cd, 0.086 Pb, 0.15 Cu, 3.9 Zn, 3.7 Fe, 0.21 Mn, and 0.081 Ni. The results are compared with values reported previously for cod from the Baltic Sea by other authors.
