Peculiarities of microelements accumulation in the organism of small mammals in the urbanization conditions

In article regularities of microelements accumulation in an organism of different types of small mammals (lesser shrew Crocidura suaveolens, mole vole Ellobius tancrei, tamarisk gerbil Meriones tamariscinus, house mouse Mus musculus and Norway rat Rattus norvegicus ) in the urbanization conditions are described. It was shown that microelements maintenance don't depend on urbanization degree. Level of accumulation the heavy metals and toxic elements in an organism of small mammals is connected with features of their biology, first of all with food specialization of types. Microelements accumulation decreases among: the types feeding on underground parts of plants - seed-eaters - insectivorous - omnivorous. In an organism the exoanthropic types higher levels of heavy metals content in comparison with obligate sinanthrops are noted.
