Rezumat: On sample plots were selected samples of model trees. The defining of the content of mineral elements and heavy metals are made in the laboratory "Arctic". Roentgenofluorescent analysis was performed by spectrometer LabCenterXRF-1800 with the use of crystal-analyzers. Preliminarily dried and crushed samples were merged in tablets. Total content of mineral elements and heavy metals in spruce was higher than in pine wood. Content chemical elements in spruce depends on the category of the trees viability is the following picture: the deterioration of the trees there is a decrease in the calcium content of 0.05%. Sapwood and heartwood differ by total content of mineral elements and metals from pine to 1-2%. The content of mineral elements and heavy metals does not depend on the location of the cross-section in the tree trunk. For spruce the greatest concentration of chemical elements, including heavy metals, marked trees fifth category viability, first category viability - for pine. Stand near a highway has a more precarious situation of forest ecosystems. Deterioration of the trees there is a decrease in the calcium content of 0.05%.
