✦ Synopsis

In 1991 geochemical mapping of sediments in the southern Baltic was begun by the Polish Geological Institute, Marine Geology Branch to determine sediment pollution, sediment spreading and the rate of accumulation of pollutants to define 'hot-spot' regions. The initial results on the concentration of heavy metals in 36 samples collected in the Gdansk Basin are presented. One 'hot-spot' is the network of channels in Gdansk Harbour where the bottom sediment (sludge) is highly contaminated. Sampling results and proposals for dredging, separation of the sand fraction, dewatering and the deposition of sludge are discussed.

The determination of 63Ni was carried out on fish samples of cod (Gadus morhua), herring (Clupea harengus), sprat (Sprattus Sprattus) and samples of sediment core from the GdaΕ„sk Bay. In contrast to stable nickel, 63Ni is non-uniformly distributed within the fish. More than 95% of total 63Ni content

The composition of the hydrobiid fauna in a coastal water of the southern Baltic was studied in 1990/91 at three stations with different sediment characteristics (grain size, organic content). Four species were found (Hydrobia venfrosa, H. ulvae, H . neglecta and Pofamopyrgus jenkinsi). H. venfrosa
