Trends in the Chemical Pollution and Dynamics of Kaliningrad Bay

The dynamics and trends in the chemical pollution of water and the bottom sediment of Kaliningrad Bay in the Vistula Lagoon are examined. Mean annual and one-moment estimates of the conditions and level of this type of pollution of water resources in the bay are given, and distribution schemes of suspended matter and pollutants over the area are shown. Schemes for calculating the components of the nearshore wave energy fluxes and water currents are also given. Environmental–dynamic zoning of the area allowed the establishing of stably localized, hydrodynamically stagnant problematic zones with high levels of chemical pollution of the water and bottom sediments (which are zones of higher environmental risk).
