This paper presents the results of the examinations of phytoplankton community of the Tamis river from March 2003 till December 2004. During the investigation it was determined 136 algal taxa from 6 divisions: Cyanophyta (10 taxa), Chrysophyta (1 taxa), Bacillariophyta (66 taxa), Pyrhophyta (4 taxa), Euglenophyta (14 taxa) and Chlorophyta (41 taxa). The contents and the structure analysis of phytoplankton as well as saprobiological valorization of water quality, has been carried out in the Republic Hydrometeorological Service of Serbia. Results of quality and quantitative analysis point to domination of Bacillariophyta and Chlorophyta. The index of saprobity given on the basis of Pantle-Buck method indicated that the quality of water of Tamis river on Jasa Tomic border locality belonged to beta and beta-alfa mesosaprobic category.

Within the pollutant analysis in sediments the total organic carbon (TOC) content is determined, as well as nutrients such as nitrogen and phosphorus. In addition to this form carbon may be present as elemental or inorganic ones, as the crucial issue for sample preparation. Total phosphorus content was determined after sample digestion with sulphuric and perchloric acid. Organic nitrogen values were determined according the Kjeldahl method. Concentrations of TC, TOC, TIC, total P, organic N and total N in river Tisza sediment samples from sites Martonos, Novi Becej and Titel during 2004 and 2005 were presented.
