В ДРЕВОСТОЯХ ПРИ ТЕХНОГЕННОМ ВОЗДЕЙСТВИИ The issues of variability of pinewood (Pinus sylvestris L.) properties in growing stock located in the vicinity of operating industrial facilities is still relevant. The paper aims to assess
the technogenic impact on the radial increment as well as the physical and mechanical properties of pinewood in the conditions of Northern Taiga. The impact of the distance from the
source of emissions on variability of the radial increment and the volume and technical
properties of wood were determined. Distribution maps of the conventional wood density
and its compressive strength along the fibers inside the trunk were formed. It is found that
with a decrease in the distance from the source of emissions, the average value of the radial
increment of trees occurs. It is revealed that there is a decrease in wood density from the
butt to the top, and from the pith to the sapwood. Also, it is determined that wood density
increases as the distance to the source of emissions decreases. However, there were obtained
no valid differences of the indicator of wood resistance to compression along the fibers at
various distances from to the source of emissions.
