Abstract
Aim. The study of microbiological and geochemical processes occurring in the soil strata, composed of dispersed rocks, when they are in contact with the liquid wastes of industrial production in the city of Rostov-On-Don. The most important problems connected with chemical industrial pollution of the geological environment of urban territories situabed in the regions of dispersed rocks deposit evolution are discussed. Methods. Dispersed rocks of the European part of the south of Russia are investigated by the method of laboratory modeling. Results. Olt is shown that technogenic chemical elements entering geological environment with liquid industrial wastes not only worsen ecological state of the environment maintaining existence, but the are a factor of structure formation of dispersed rocks; they also can be a source of feeding for microorganisms, and hence, make more active microbiogeochemical reactions in dispersion ground strata. The number ahd composition of microflora of dispersion rocks are experimentally studied. The assessment of the possible effect of microbiological processes occurring in dispersed rocks on their engineer and geological properties is given. Findings. Chemical pollution of masses that are composed of dispersed rocks, on urban ecosystems and its intensity are the result of waste water infiltration and chemical activity of dispersion rocks. It leads to the development of engineer and geochemical processes disturbing physical–chemical and biogeochemical equilibrium in dispersed thickness and homeostasis of natural-technical system on the whole, that can worsen conditions of man vital activity as well. The assessment of the presumable influence of microbiological processes occurring in areas with dispersed rocks on the engineering-geological properties of the composing rocks has been given in the paper. These problems are urgent for all urbanized territories formed by the massives of dispersed rocks.
