Аннотация: The ecotopic difference in the accumulation of Ni, Zn, Mn, Al, Se, Cs, La and Sm in bryophyteCeratodon purpureus (Hedw.) Brid was studied during a long-term experiment in the anthropogenicallydisturbed environment of Donbass. The concentrations of elements in moss gametophytes were determinedby neutron activation analysis. The moss samples were exposed from November 2018 throughMay 2019 at 24 test plots in the central Donbass with varying degrees of technogenic transformationof geosystems. When comparing ecologically stressed areas with intact or restored ecotopes, the differencein the accumulation of Ni was 6.9 times, Zn – 10.2, Mn – 6.3, Al – 5.3, Se – 9.6, Cs – 3.9, La –5.9, and Sm – 5.4 times. There were structural and functional modifications in the leaf apparatus ofbryophyte, suitable for using in further phytomonitoring studies for express diagnostics. According to theresults of the factor analysis, two groups of pollutants were identified, differing in the source of origin:(1) Al, Ni, Mn, and Zn, (2) Cs, Se, La, and Sm. The obtained data are considered as part of the primaryscreening of biogeochemical characteristics in the Donbass in 2018–2019. Within the gradient of toxicload and local impact, the leading role of mining and metallurgical facilities in the pollution of naturalecosystems of Donbass was proved.
