DIFFERENCES OF CHEMICAL COMPONENTS IN BEACHES SEDIMENTS WITH DISSIMILAR ANTHROPOPRESSURE
Journal Title: Baltic Coastal Zone - Year 2011, Vol 15, Issue 15
Abstract
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 of sea water was manifested in the high content of organic matter in places having permanent contact with sea water. The content of the organic matter increased together with with the depth of settlings in these places. However more organic matter in surface layers was observed in regions more distant from the sea, because penetration of organic matter into the sediments is possible during precipitation. The concentration of ammonia nitrogen in the analyzed beach deposits increased with depth, what probably results from the lower oxygen content in deeper layers. It was confirmed that organic matter in sands of the beach in Czołpino is of natural origin, while in Ustka it is primarily of anthropogenic origin.
