Determination of total organic carbon content (TOC) and trihalomethane formation potential (THMFP) as well as correlation of those two parameters is recommended for monitoring of water bodies which are considered as drinking water resources. Those parameters would enable a categorization of water bodies from the protection point of view as well as from view of their usage as drinking water sources. Relationship between TOC and THMFP is dependent on the origin and the structure of organic matter in water. In this paper the correlation of TOC and THMFP is given for different kind of resources.

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.

Organic matter of various composition is present in soils and sediments ranging from simple compounds to the very complex proteins, etc. Within the pollutant analysis in soils and sediments the total organic carbon (TOC) content is determined. In addition to this form carbon may be present as elemental or inorganic ones. TOS identification and quantitation methods may be qualitative or quantitative with prior sample preparation. It is recommended catalytic combustion of samples at high temperatures with Pt catalyst and IR detection of evolved CO2.
