Abstract
It was shown that hilly peatbogs had proved to be informative in estimating technogenic changes of the environment. It was established that active accumulation of heavy metals and sulfur took place in the upper levels of peat deposit (on the depth of 5 cm, more rarely - 15 cm). Passage of technogenic fluxes through peat deposit did not exceed 30-35 cm. The control of negative changes under the effect of sulfur emissions was proved desirable to carry out in bog ecosystems of the Rybnaya River valley. Negative changes happening due to the impact of heavy metals should be controlled on the territories near industrial enterprises of the cities Norilsk and Talnakh.
