Bottom sediments samples for chemical analysis were derived from Gowienica river and its tributaries. Samples were taken at 2014 and 2015 years from established sampling points on differently managed and utilized adjacent areas. Total content of heavy metals, i.e.: Cd, Co, Cr, Ni, Pb and Hg were measured in collected material. The results indicate that concentrations of lead, nickel, chromium and mercury exceeded level below which no harmful impact of pollution (TEL) is noted, but none of the analyzed heavy metals exceeded the limit (PEL) above which harmful effects of pollution on organisms can be observed. However, according to other classification (LAW) analyzed sediments were located between two classes (deposits unpolluted - Class I), and deposits unpolluted / moderately polluted (class I-II). However, chemical analysis showed the various points exceeded the natural cobalt concentration (geochemical background; 2.0 mg⋅kg^-1) for aquatic sediments in Poland. The reasons of cobalt concentration exceedance in natural sediments, among others, were surface runoff from fields and meadows in the form of fertilizers, plant protection products and the domestic waste water.
