It was determined that in all researched points of Jiloy region plants Salsola nitraria and Toumefortia sibirica intensively accumulate heavy metals and they could be used as а bioindicators of environmental ecological monitoring. However plants resistance to increasing content of heavy metals and ability to store the high concentrations present danger for people and animals health as а result of toxicants penetration to nutrition chains. It was determined that certain plants and animals are аble to form metals resistant population’s thanks for their genetic variability. Introduction chromosome aberrations in bone marrow cells of R.opimus is the important genotoxic The progressing influence of the features characteristics of environmental environmental factors of animals and plants contamination of oil, oil products and heavy natural populations requires the detailed metals both as intensity of the mutation ecology-genetic analysis. Small mammals process. (Bigaliev А.В., 1986; Gyleva Е.А., play а major role in estimation of the natural Kosareva N.L.,1993). The amount of works ecosystem’s state. That’s why we have led the the cytogenetic study of natural animal present research of potential mutagenic populations is not numerous. Such approach danger estimation of environmental pollution for the characteristics of natural population’s of oil, oil products and heavy metals effects state supposes receiving of cytogenetic data using the natural populations of big Rodents the various animal species for information (R.opimus) as а test-system.
