V prispevku so predstavljeni izsledki raziskave sedimenta v barskem jezercu na Pohorju. Spreminjanje planktonske združbe vodnih bolh in kremenastih alg, katerih ostanki se nabirajo v sedimentu, so odraz spreminjanja okoljskih dejavnikov. 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.
