This article presents results of complex investigations conducted in the autumn 1994 and summer 1995 by the Water Ecology Laboratory of the Institute of Environmental Protection, Branch of Gdansk. The research was a continuation of studies commenced in summer 1992, within the framework project 'Development of a system of protection and restoration of the Gulf of Gdansk biocenosis' (Kruk-Dowgiallo and Ciszewski 1995; Kruk-Dowgiall?o and Dubrawski 1998). The project was financed from the statutory funds of the Institute of Environmental Protection (IEP). The estimation of industrial fish contamination extent was done on the basis of 1992-1994 studies, supervised by Dr Urszula Potajallo within a Project Research required by SRC (Scientific Research Committee) which was realized in the Institute of Marine and Tropical Medicine in Gdynia (Potajallo et al. 1995). The state of coastal sediments state estimation was provided on the basis of seasonal studies carried out in 1995-1996 within a MS thesis experiments performed in (IEP) by Aleksandra Kula, supervised by Dr Rajmund Dubrawski.

The recently revised check-list of diatoms found in Germany contains 1437 taxa (1632 taxa have been recorded for Central Europe). Clear correlations with ecological conditions were established for 1000 taxa (70% of 1437). 267 predominantly marine taxa also occur in inland waters; they penetrate progressively into rivers contaminated with industrial waste waters. 61 taxa are aerophilic and 164 eutraphentic, 91 tolerant to all trophic conditions. Very few species in these ecological groupings are endangered. However, at last 417 oligo- or slightly mesotraphentic taxa are included in the 'Red List'. This strongly indicates that conserving oligo- and dystrophic waters as well as lower mesotrophic habitats can best protect species diversity.
