Abstract
The composition of macroelements (Al, Si, P, Mn, Fe, S, Cl, etc.) and microelements (Cd, Pb, Zn, Cu, Ni, Co, Cr, etc.) in fir needles and in bushes of the Baikal biospheric reserve is considered for the purpose of revealing the reasons of shrinkage of fir forests. No high content of elements (including those indicating anthropogenic action, first of all from the Baikal Pulp and Paper Plant) was detected in fir needles and in the branches (with leaves) of bushes (except raspberries), which indicates the absence of a substantial arrival of inorganic elements of anthropogenic origin. The detected levels of the investigated chemical elements in fir needles cannot be the reason of degradation of fir forest within the reserve. Anomalous Cl content in raspberries is of unclear nature and requires further investigation.
