摘要：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 dynamics of change occurred in the last 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 showed that the sediment at the depth of 14 cm is about 100 years old. The presence of spheroidal carbon particles (SCP), a consequence of the use of fossil fuels, confirmed dating by radiunucleids.
