ABSTRACT
Cobalt (Co) and vanadium (V) are so-called transition metals, which are analysed with regard to their environmental characteristics. Co was found in the bottom sediments examined in amounts ranging from 3.0 mg/kg to 90.0 mg/kg (median – 15.5 mg/kg) as against its natural content in regional aqueous sediments of 4.0 mg/kg. V content found in water body sediments ranged from 12.0 mg/kg to 155.0 mg/kg (median – 72.0 mg/kg) as against the natural level of 12.0 mg/kg. Only in one out of the 35 examined water bodies did bottom sediments contain Co and V at natural geochemical background levels; in the remaining water bodies, natural concentrations of the elements in question were exceeded, pointing to anthropogenic pollution.

Keywords: bottom sediments, trace elements, water reservoirs, lake, cobalt, vanadium.
