Abstract The development of the mining industry has led to the appearance in many parts of the world of vast technogenic territories from which toxic heavy metals enter the environment and food chains. Physical, chemical, and biological methods of cleaning industrial land due to technological complexity and high cost are relatively little used on a large scale. Natural forest overgrowth of mining sites and the removal of heavy metals by woody plants can be an effective form of recovery. Therefore, the study of this process is of significant scientific and practical interest. The analysis of the annual growth in height and width of the annual rings of the stem of Scots pine (Pinus sylvestris L.) in 2004–2019 was made on the territory of the Uchalinsky mining and processing plant (South Ural, Russia) contaminated with heavy metals. Relatively high concentrations of copper and zinc were found in soils, roots, bark, young shoots, comparable to exceeding the maximum allowable concentrations. Despite the spatial uniformity of the heavy metal content in The online version is available at http://www.springerlink.com. Corresponding editor: Zhu Hong.

Introduction Industrial pollutants cause significant harm to human health due to their toxicity, long-term circulation of substances, and the pollution of all components of natural ecosystems (Aelion et al. 2009). Among them, heavy metals dominate which, together with mineral oils, are a source of pollution to 60% of soils of European Union countries. The total cost 4
