Research on toxic substances in the Gdansk BAsin was done in the form of individual projects.Elevated concentration of cadmium, lead, and zinc were recorded in water at stations located near the cities of Gdansk and Gdynia.THe degree of pollution of bottom sediments by trace metals was estimated by calculation of the enrichment coefficient (EF) of the surface layers.The highest values of the enrichment coefficient for trace metals were recorded in the deepest parts of Puck Bay and in the Gdansk Deep.The trace metal distribution in the Gdansk BAsin is practically identical with that of organic carbon concentrations.The natural variability of metal concentrations in fish was very broad.Neverthlass, investigations done hitherto have shown that metal concentrations in tissues of fish intended for human consumption do not exceed permitted levels.No transgression of permitted levels has been found either for DDT or PCBs.Polycyclic aromatic hydrocarbons are belived also to be metabolised in marine organisms; however, it is belived that they might affect reproduction and physiolgical processes in demersal fish.
