Quantification of heavy metals in micromammals communities of transformed ecosystems

In the article total content of microelements is examined in the populations of background species of micromammals. Comparative description of toxicants accumulation was undertaken in populations of biogeocenoses in industrial steppe Pridneprovya different by their contamination level. The obtained data allow to estimate the quantity of microelements entering environment from the associations of micromammals.
