Megjegyzések:	The organic matter of the sediment is prerequisite for the detritivorous community in the riverecosystem. To quantify this organic matter content and its changes in time and space, investigations wereperformed at two typical sites of the Hungarian Danube, which differ in their local hydrological characteristicsdue to the deposition and erosion processes. The distribution of the benthic particulate matter and the organicmatter content of that were analysed in the core samples of the river side and the near shore line in three layers(0-5, 5-10 and 10-15 cm) and in four fractions: Coarse (2360-710 mm), Fine (710-250 mm), Very fine (250-63 mm) and Ultra fine (<63 mm). The variability of the organic matter content was highest in the coarse fraction(CV: 86%), while it was the lowest in the ultra fine fraction (CV: 20%). Sites differed mainly in the organicmatter content of the C and F fractions, and the vertical changes of the benthic organic matter. The first TBOMrecords from the studied section of the Danube show relatively high values in comparison with the literature.Results show, that mainly the quantity of the fractions (i.e. hydrological characteristics) determined the BOMcontent of the bed sediments at the investigated sites.
