摘要：The paper presents the results of a study of the state of the environment in the area of the Kola Mining and Metallurgical Plant using a bio-indicator of the Siberian spruce needles (Picea obovata). The following deviations in the morphometric parameters of Picea obovata needles were found: a decrease in the length and width, a reduction in the total surface, different types of damage and wilting. In areas with a more intense impact, a regular increase in the average percentage of damaged plants is observed compared to baseline samples. The state of the environment for the suppression of the Siberian spruce needles was assessed as "satisfactory" and "good".
