Effects of heavy metal concentrations on biological activity of soil micro-organisms
Original language description
The distribution of cadmium, lead and zinc in exchangeable, organic, and 2M HNO3-extractable fractions as well as the effect of heavy metal concentration on soil microflora was investigated. Six sampling transects were chosen in the Litavka River alluvium in the years 1999-2001. Concentration of all metals increased with decreasing distance from the source of contamination. The concentrations of Cd and Zn in exchangeable fraction were higher in organically bound fraction, reverse trend was found in Pb speciation. All measured parameters of soil microbial activity were affected by heavy metals concentration. The decrease of CFU was most significant in case of oligotrophic bacteria and spore-forming bacteria. Significant inhibition of C-biomass occurredin soils highly contaminated by heavy metals. Cbiomass:Cox ratio decreased with increasing soil pollution. Generally, the values of enzymatic activities were highest in soil above the source of contamination and they were decreasing appro
