EFFECT OF COPPER SMELTER EMISSIONS ON THE STEM SHAPE OF SIBERIAN SPRUCE (PICEA OBOVATA LEDEB.) AND SIBERIAN FIR (ABIES SIBIRICA LEDEB.) (PINÁCEAE, PINOPSIDA)

Authors: Bergman I. E.

The influence of industrial pollution on the stem shape of Siberian spruce and fir trees was estimated in the Middle-Ural Copper Smelter vicinity (Revda, Sverdlovsk region, the southern taiga). As the pollution source is approached, the stem taper increases with a decreasing form factor. A statistically significant increase of the stem taper of Siberian spruce in the butt end (by 22.9%), the lower (35.7%), middle (18.0%) and upper (9.0%) parts of the stem is shown.

BLOOD SYSTEM OF VOLES UNDER (CRICETIDAE, RODENTIA) INDUSTRIAL POLLUTION

Authors: Tarakhtii E. A., Mukhacheva S. V.

A complex of the blood system characteristics and the concentrations of heavy metals (Cu, Zn, Cd, and Pb) in the liver of bank voles (Cl. glareolus) and red voles (Cl. rutilus) from background and industrial polluted areas were studied. Heavy metals were found to affect the structure of erythrocytes, the blood cell composition and concentration in the hematopoietic organs. The revealed differences between the blood system's responses of bank and red voles to pollution conditions are due to different levels of the pollutant accumulation in the body.
