Metal concentrations in biota; Concentration of other organic contaminants in biota


The Contaminant Programme in marine biota constitutes an integrated part of the national monitoring activities in the marine environment as well as the international programmes within ICES, OSPARCOM and HELCOM. The programme is financed by the Swedish Environmental Protection Agency. The dab is a bottom living species feeding on crustaceans, mussels, worms, echinoderms and small fishes. The males become sexually mature between 2-4 years and the females between 3-5 years. The spawning takes place during the period April - June. The dab tends to migrate to deeper water in late autumn. Dab is among the 'first choice species' recommended within the JAMP (Joint Assessment and Monitoring Programme). Dab is collected from the Kattegat (Fladen) in the autumn. Liver tissue samples are analysed for lead, cadmium, copper and zinc and muscle tissue samples are analysed for organochlorines and mercury. The dab specimens are age determined by otoliths. Specimens between 3-5 years are analysed.
