Industrial contamination leads to modifications of the environmental abiotic conditions on a geochemical scale, and as a result, to the formation of new ecosystems. using the emission of a zinc and lead smelter as an example, the generation is indicated of an industrial borderline of trees and forest. The state of the pine forest vegetation has been studied along with the radial growth of pines. Substantial changes have been found in the pine wood structure on the industrial timberline, these changes manifesting themselves in the diminution of the number and size of tracheids, as compared with the non-contaminated control region.
