ABSTRACT. The annually increasing level of anthropogenic load associated with increasing urbanization and technogenic load negatively affects ecological systems and biocenoses in particular. One of the most dangerous fac-tors of such impact is the accumulation of xenobiotic elements in the environment. Among the toxic elements, one of the most dangerous is cadmium, which not only has a high level of cumulative effect, but also pronounced antagonisms with a number of vital essential elements. In our work, we present the data on the distribution of this element in the structure of the chain of ecological interaction water-soil-plant-animal-human on the example of the central zone of the Orenburg region. The presence of a pronounced accumulation of cadmium in soil samples and biosubstrates of farm animals was experimentally established; it should be noted that the level of cadmium in all stu-died samples was within the biologically acceptable level.

KEYWORDS: cadmium, bioaccumulation, biocenosis, biosubstrates.
