In pot experiment the effect of loamy sand contaminated with cadmium, copper, zinc and lead on number of oligotrophic bacteria, actinomycetes and fungi was studied. Heavy metals were applied to soil as a single pollution and in mix each other. Two level of heavy metals pollution were examined: 1st level (mg kg–1 of soil): Cd – 4, Cu – 150, Pb – 100 and Zn – 300; 2nd level (mg kg–1 of soil): Cd – 12, Cu – 450, Pb – 300 and Zn – 900. It was found that oligotrophic bacteria were the most sensitive on contamination of soil with cadmium, copper, zinc and lead, slightly less – actinomycetes and the least susceptible were fungi. The negative effect of heavy metals on microorganisms was not the sum of single heavy metals action.

W doświadczeniu wazonowym badano wpływ zanieczyszczenia piasku gliniastego kadmem, miedzią, cynkiem i ołowiem oraz ich mieszaninami w różnych proporcjach na liczebność bakterii oligotroficznych, promieniowców i grzybów. Zastosowano 2 poziomy zanieczyszczenia, które wynosiły [mg kg-1 gleby]: I poziom: Cd - 4; Cu - 150; Pb - 100; Zn - 300; II poziom: Cd - 12; Cu - 450; Pb - 300; Zn - 900. W wyniku badań stwierdzono, że bakterie oligotroficzne były najbardziej wrażliwe na zanieczyszczenie gleby metalami ciężkimi (kadmem, miedzią, ołowiem i cynkiem), nieco mniej - promieniowce, a najmniej - grzyby. Negatywne oddziaływanie metali ciężkich na drobnoustroje nie miało charakteru addytywnego, tzn. nie było sumą skutków działania pojedynczych metali.
