The paper presents the results of sediment analyses done at a small moor lake on Pohorje. The changes in the plankton association of water fleas and diatoms whose remains accumulate in the sediment are a reflection of changing environmental factors. It was determined that the greatest dymanics of change occured in the 150 years, which coincides with the beginnings of industrialization. The age of the sediment has been determined by the analyses of the activity of the radionuclides 137Cs, 210Pb, and 241Am, which showedthat the sediment at the depth of 14cm is about 100 years old. The presence of spheroidal carbon particles (SCP), a consequence of the use of fossil fuels, confirmed dating by radiunucleids.

Abstract

V prispevku so predstavljeni izsledki raziskave sedimenta v barskem jezercu naPohorju. Spreminjanje planktonske združbe vodnih bolh in kremenastih alg, katerih ostanki se nabirajo v sedimentu, so odraz spreminjanja okoljskih dejavikov. Največja dinamika sprememb je ugotovljena za zadnjih 150 let, kar sovpada z začetki industrializacije. To potrjujeta tudi analizi aktivnosti radionuklidov 137Cs, 210Pb in 241Am, ki so pokazale, da je sediment na globini 14 cm star okoli 100 let in prisotnost kroglastih ogljikovih delcev (SCP), ki so posledica uporabe fosilnih goriv.
