- Аннотация: The ecotopic difference in the accumulation of heavy metals (Zn, Cu, Fe, Mn, Ni, Cd, Pb) by botanical objects of indicator significance has been proven. To assess air pollution in Donbass, it is recommended to use the species Ceratodon purpureus (Hedw.) Brid and Bryum argenteum Hedw. to check the accumulation of pollutants in gametophytes and Populus nigra L. on the specific content of the dendroindicator seeds in chalase capillary bristles. The studies were carried out in the the registration sites of the monitoring network in the central Donbass. The plants in the zones of technogenic and particular anthropogenic impacts (industrial enterprises of the metallurgical complex, dumps of coal mines, places of transport load on ecosystems, residential ecotopes) were studied incomparison with the territories of minimal transformation in the zones of the natural reserve fund in the Donetsk region. For the bryophytes of 11 species of the regional natural flora, taxonomic specificity in the accumulationof heavy metals was established, the facts of hyper- and hypoaccumulation in the thalli of bryobionts were noted. Based on the actual accumulation of heavy metals, the facts of the phytogeochemical migration activity of elementsin the surface layer of the atmosphere of an industrially intense region were established. Accumulation of heavy metals in bryophytes occurs during precipitation, and in black poplar seeds freely floating in the air, as a result ofactive capture of dust particles, which causes a difference in accumulation by different phytosubstrates. The facts of the pollen content in other species of poplar fluff have been established, which is also considered in the context of a possible increase in the seasonal allergenic effect in the population.
