Abstract
Pollution of the ecosystems of downstream tailing dumps of gold extracting factories in the permafrost zone is considered. Primary and secondary toxic effects of cyanide technologies are distinguished. The conclusion is made that the ecological risk of pollution with heavy metals and arsenic is the most significant. Geological environment is of great importance in formation of man-caused anomalies: silicate medium prospers their expansion, carbonate one decreases man-caused effect on conjugate ecosystems. The data on the reaction of ecosystems to man-caused pollution are obtained using bioindicative method of fluctuating skewness. When pollution of ecosystems occurs, fluctuating skewness of vegetation increases, or, in other words, reaction to pollution is reflected on their physiologo-morphological level.
