The analysis of bottom sediment quality is an important yet sensitive issue. The anthropological influences (i.e., urban, industrial and agricultural activities) as well as the natural processes (i.e., changes in precipitation amounts, erosion and weathering of crustal materials) degrade surface water quality and impair its use for drinking, industrial, agricultural, recreational and other purposes. Due to spatial and temporal variations in water chemistry, a monitoring program that provides a representative and reliable estimation of the quality of surface waters has become an important necessity. Heavy metals are usually present at low concentrations in aquatic environments but deposits of anthropogenic origin have raised their concentrations, causing environmental problems in rivers. This research was realised in order to determine and analyse selected heavy metals present in sediment samples from six river basin on East of Slovakia, representing by the rivers Hornad, Laborec, Torysa, Ondava, Topla and Poprad. Sampling points were selected based on the current surface water quality monitoring network. Investigation was focused on heavy metals (Zn, Cu, Pb, Cd, Ni, Hg, As, Fe, Mn). The content of heavy metals reflected the scale of industrial and mining activities in a particular locality. The degree of sediment contamination in the rivers and their comparison, has been evaluated using a Pollution load index.
