Study of aerotechnogenic pollution in the territory of the Murmansk region using the samples of common pine

Alexandrova E. Yu., Trotcenko A. A.

The article presents the results of a bio-indicative assessment of the state of the environment in the impact zone of the Severonikel integrated industrial complex. It assesses the general state of conifers, determines their stability class, studies the morphometric characteristics of common pine needles, and environmental classes of the target area. Within the framework of the study, we noted a decrease in the linear parameters of the needles, a deterioration in the vital state of the trees when approaching the area of technogenic impact of the Severonikel plant. The state of the environment in Monchegorsk district of the Murmansk region was also determined: up to 20 km from the source of exposure – a zone of increased environmental hazard, 20–30 km – a zone of relative ecological well-being, over 70 km – an environmentally safe zone.
