The aim of this project was to study the fate of chemically persistent organochlorine xenobiotics in the marine link of the food web, between penguins and herrings (Clupea harengus), which are the only food for Spheniscus demersus from the Gdańsk Zoo. Concentrations of hexachlorobenzene (HCBz), pentachlorobenzene (PCBz), trichlorobenzene (TCBz) and the .- HCH isomer were determined in Baltic herrings,...
The abundance of actinomycetes, filamentous fungi and yeasts in the marine epipsammon habitat and their spatial distribution were studied with conventional plating techniques in two marine beaches (Ustka and Czołpino, southern Baltic Sea) which are characterized by different anthropic pressure levels. Actinomycetes constituted the predominant group of studied microorganisms, while the least numerous...
