Influence of heavy metals on soil microflora
(Wydawnictwa AGH, 2010) Hołda, Anna; Kisielowska, Ewa; Niedoba, Tomasz
The purpose of the research presented in the paper was to conduct the heavy metals contents in area of tannery plant and to determine their influence on soil microflora. The soil samples were collected to this purpose from the area, which was surrounded by the industrial buildings from one side (tannery, galvanic plant and chemistry plant) and by river Wilga and two small ponds from three remaining ones, which supposedly collect the sewers from these plants. The collected samples were then chemically and microbiologically analyzes. The contents of metals as Cu, Cd, Pb and Zn were determined by culometric method. On the basis of conducted analyzes it was proved that soil on the researched area was polluted by heavy metals. Mainly chromium contents in every sample was high what means that the tannery wastes occurs in the area of collecting samples. The investigation proved the influence of heavy metals on soil microflora. Various sorts of microorganisms have various tolerance on high metals concentration. The most resistant were ferruginous, nitrificative and denitrificative bacteria, the less resistant were meso- and psychrophilic bacteria and fungi.
