The 15 - cm layer of bottom sediments of the Lake Bukowo was examined. Organic sediments make up to 32% of the Lake Bukowo bottom surface, the mixed sediments - 52% and the sandy ones - 16%. Bottom sediments of this lake displayed a high content of organic matter ca. 28%, nitrogen ca. l. 2%, silica 65% and phosphorus 0.9%. Nitrogen and phosphorus were deposit into sediments in the main form of organic...
Estuaries are dynamic ecosystems characterized by great and constant variability of physicochemical gradients and biological parameters. Considerable fluctuations in salinity levels, temperature, pH, concentrations of oxygen, nutrients and organic matter are quite natural in such water bodies. There are many estuarine forms at the Polish Baltic Coast, including open-sea gulfs (the Gulf of Gdansk and...
This paper deals with the evaluation of the sanitary state of bottom sediments of the Lower Vistula along the section from Wyszogród to Toruń. The contamination extent of bottom sediments by easily decomposable organic matter and substances of faecal origin was defined based, respectively, on the number of heterotrophic bacteria capable of growth at 22°C and the occurrence of faecal coli (FC) bacteria...
The investigations of the chemical composition of sands were conducted on the beach in Ustka and Czołpino. The Ustka is a typical tourist town and Czołpino is located in the Slovinski National Park away from urban or rural areas. The beach sediments in Ustka contain much more organic matter, nitrogen and phosphorus compounds as well as calcium carbonate than analogous deposits in Czołpino. The effect...
Beach sediments from two beaches at the Polish coast of the Baltic Sea were collected and analyzed. The sediments were collected in two seasons – winter and summer – at two stations, depending on the influence of the sea water on the examined sediments. At each station, surface sediments (0-5 cm) were collected as well as sediments at the depth of 10-15 cm. The results of the conducted tests reveal,...
Sandy sediments coming from three beaches of the southern Baltic Sea were collected and analyzed. Investigated beaches were divided according to strength of anthropogenic impact and degree of sheltering. The first beach was situated in Ustka on the eastern side of the mouth of the Słupia River, second in Czołpino and the last one in Puck. Core sediment samples were collected seasonally, depending...
