All living systems, including the soil–pine system, are affected by some external and internal factors. The balance of a system depends on the nature of the influencing factors and the extent of their impact. When the balance is disturbed, the quantitative and qualitative changes in the chemical composition and the functions of a tree can be observed. Using the method of dynamic factors it has been deter - mined that a biotic factor (a pathogen) stimulates biophilicity and bioaccumulation of macroelements in the pine tissue, whereas an abiotic factor (pollution) intensifies biophilicity and bioaccumulation of microelements. The external abiotic factor (pollution) has a stronger influence on the linear logarithmic distribution of metal concentrations in the soil–pine system than the external biotic factor (a pathogen). The strongest effect is produced on the balance between metal concentrations in pine tissue and the concentration of metals in the mobile form in soil.
