I. P. Pinchuk, N. P. Kirillova, L. M. Polyanskaya & D. G. Zvyagintsev
Number, biomass and size of bacterial cells were studied in the rhizosphere and rhizoplane of six different species of higher plants. These indexes are higher in the root zone of plants than in soil without plants. Average size of the bacterial cells in rhizoplane and rhizosphere increases, as compared with the soil by root exudates. Calculated rhizospheric and edaphopheric effects confirmed that the basal area is favorable for growth and development of bacteria. Number of...

Integral parameter of critical loads as a basis for environmental regulation of landscapes contamination with heavy metals

S. A. Tobratov
The method of evaluation of landscape carrying capacity on the basis of the permissible limits for heavy metal accumulation in phytomass, surface waters and soils has been suggested. Like the already known method of critical loads (CL), the proposed method aims to identify natural mechanisms of ecosystem self-purification from pollutants and to indicate the early stages of anthropogenic chemical contamination. However, in contrast to CL, the proposed method takes into account the ecological role of...
