The territory of modern central Donbass is considered as an experimental site for the implementation of an ingredient biomonitoring program. Bryophytes were transplanted and exposed in the geolocalities of the direct impact of enterprises of coal mining and processing complexes, metallurgical and chemical industries, ruderal and residential ecotope...

... The biocheochemical peculiarities of the territory of modern Donbass have been little studied so far. Technogenic processes in combination with the factor of hostilities (Gosudarstvennyi komitet, 2022) brought a geochemical contrast here, when the content of individual elements in indicator substrates varied significantly in the environment (Safonov et al., 2023). ...
... Brid were sampled in the buffer zone of the Republican Landscape Park "Donetsky Kryazh". This species was set as a model one due to its wide ecological niche and the highest survival rate compared to other moss species, also dominant in the region, as obtained in previous studies Safonov and Morozova, 2021;Safonov et al., 2023). In November 2018, the samples of live moss were transplanted to the test plots (Fig. 1); all of them were in the same conditions (open to the precipitation). ...
Проведен мониторинговый эксперимент установления экотопической разницы по накоплению Ni, Zn, Mn, Al, Se, Cs, La и Sm мохообразным Ceratodon purpureus (Hedw.) Brid в условиях антропогенно нарушенной среды Донбасса. Концентрации элементов в гаметофитах растения определены методом нейтронного активационного анализа. Экспозиция образцов проводилась с ноября 2018 г. по май 2019 г. на 24 учетных площадках Центрального Донбасса с разной степенью техногенной трансформации геосистем. Показана разница по накоплению Ni в 6.9, Zn – 10.2, Mn – 6.3, Al – 5.3, Se – 9.6, Cs – 3.9, La – 5.9 и Sm – 5.4 раза при оценке экологически напряженных территорий в сравнении с малонарушенными или восстановленными экотопами. Установлены структурно-функциональные модификации в листовом аппарате бриофита, пригодные для которые рекомендованы для фитомониторинговых исследований в экспресс-диагностике. По результатам факторного анализа были выделены две группы загрязняющих элементов, различающихся по источнику происхождения: в одну из них вошли Al, Ni, Mn, Zn, в другую – Cs, Se, La, Sm. Реализованный опыт рассматривается как элемент первичного скрининга биогеохимических характеристик в Донбассе периода 2018–2019 гг.
The ecotopic difference in the accumulation of Ni, Zn, Mn, Al, Se, Cs, La and Sm in bryophyte Ceratodon purpureus (Hedw.) Brid was studied during a long-term experiment in the anthropogenically disturbed environment of Donbass. The concentrations of elements in moss gametophytes were determined by neutron activation analysis. The moss samples were exposed from November 2018 through May 2019 at 24 test plots in the central Donbass with varying degrees of technogenic transformation of geosystems. When comparing ecologically stressed areas with intact or restored ecotopes, the difference in 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 of bryophyte, suitable for using in further phytomonitoring studies for express diagnostics. According to the results 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 primary screening of biogeochemical characteristics in the Donbass in 2018–2019. Within the gradient of toxic load and local impact, the leading role of mining and metallurgical facilities in the pollution of natural ecosystems of Donbass was proved.
