“…According to Uzbek and Halahan, in the technogenic landscapes, the edaphotope is a man-made, spatially limited bioinert system that is in constant development under the influence of soil formation factors [1]. In work [2], the contribution of the moss cover Campylopus introflexus (Hedw.) Brid.…”

Landfills cause significant technogenic pressure on the environment, being the center of depositing large volumes of hazardous materials in a relatively small area. Interacting with each other they form hazardous substances and compounds. In this study, we describe three genetic soil horizons that are within the impact zone of the landfill of a city of millions of people. It was established that the distribution of mobile forms of heavy metals according to the profile of the studied soils tended to gradual decrease with depth. When describing the genetic horizons of three profiles located in the impact zone of the landfill, it was established that the content of heavy metals in them does not exceed the MPC, except for Pb. The soil at the foot of the landfill turned out to be the most contaminated with heavy metals (profile No. 3). The activity of micromycetes in this soil was the lowest here. In general, all soils in the impact area of the landfill are impoverished in micromycete distribution. The taxonomic composition of mycelial fungi and the identified species’ ecological and biological characteristics indicate significant ecosystem pollution by household waste.

The tolerance of vegetative and generative clones of mosses of B. argenteum and F. hygrometrica from background and anthropogenically transformed territories to the influence of heavy metal ions was experimentally investigated. It has been established that the increase of the resistance of moss to the influence of heavy metal ions occurs through the activation of growth and physiological-biochemical processes. The level of adaptability of mosses depended on the concentration of toxic ions, the growing environment, and the vital strategy of the moss. It was established that with increasing concentration of lead ions in the environment, the generative propagation of mosses was suppressed, the percentage of germination of spores decreased, the differentiation of protonema and the speed of gametophore development slowed down, the size of cells, number and size of leaves decreased. Obviously, under the influence of elevated lead concentrations, significant changes in metabolic processes occurred in moss cells and showed signs of xeromorphism. The results of the analysis of the rates of gametophyte differentiation and the state of the antioxidant system of mosses B. argenteum and F. hygrometrica, depending on the content of heavy metal ions, show different adaptive capacity. Changes in the rate of gametophyte differentiation and the activity of superoxide dismutase and catalase antioxidant enzymes have been shown to be sensitive biomarkers of the resistance of generative and vegetative moss clones to heavy metal contamination of man-made territories.
