Особливості накопичення важких металів органами та тканинами мікромамалій у різних за ступенем забруднення біогеоценозах

Microelements accumulation features are considered in micromammals’ organism taken from different degrees transformation biogeocoenosis of Dnipropetrovs’k region. Coefficients of accumulation are defined in different organs and tissues. Accumulation of heavy metals in the micromammals’ organism in different ecosystems, with a different technogenic contamination is heterogeneous. Organs which defined asconcentrators are spleen, heart and gonads. They have primary accumulation of heavy metals. Organs–deconcentrators are those which have active extraction of microelements (liver, kidneysand and intestine). Tendency to the decline of microelements accumulation intensity in animals from strongly transformed biogeocoenosis are stated. Formation of the special barriers of accumulation and excretion from organism by organs–deconcentrators testifies to making an adaptive mechanism at the level of physiology-biochemical processes and, first of all, the metabolism intensification.
