Почвы являются важнейшими компонентами всех наземных экосистем и играют роль пространственной основы экосистем. Несмотря на многочисленные исследования, проведенные в различных секторах Антарктики, почвы этого региона остаются недостаточно изученными. Целью данного исследования является изучение процессов биогенной аккумуляции вещества и биогенно-абиогенных взаимодействий в почвах Берега Правды и архипелага Хасуэлл, Восточная Антарктида — окрестности круглогодичной станции Мирный. В ходе исследования были проведены полевые наблюдения и лабораторные анализы почв, с акцентом на определение химического состава и уровней накопления органического вещества. Установлено, что почвы имеют умеренно кислую и близкую к нейтральной реакцию. На острове Хасуэлл зафиксированы высокие уровни накопления общего углерода, обусловленные орнитогенным влиянием. В отличие от других почв Восточной Антарктиды, здесь наблюдается наличие гумусоподобной плазмы. Изученные почвы характеризуются низким (или умеренным) уровнем загрязнения согласно геоаккумуляционному индексу Igeo, однако отмечается увеличение темпов аккумуляции поллютантов в орнитогенных местообитаниях и на поверхности торфяных горизонтов.</p></abstract><trans-abstract xml:lang="en"><p>In view of the continuing human expansion in Antarctica, it is crucial to implement a wide range of measures to effectively protect the natural environment and uphold the fundamental principles of the Antarctic Treaty system. Soil is the most important component of all terrestrial ecosystems, which plays a crucial role as the spatial basis of ecosystems. Despite the considerable research performed in different sectors of Antarctica, soils and soil-like bodies of Antarctica remain poorly investigated. The aim of this study is to investigate the processes of biogenic accumulation of substances and biogenic-abiogenic interactions in the soils of the Pravda Coast and the Haswell Archipelago, East Antarctica — vicinities of the Antarctic station Mirny. Field observations and laboratory analyses were conducted, focusing on determining the chemical composition and levels of organic matter in the soils. It was found that the soils exhibit a moderately acidic to near-neutral pH. High levels of organic carbon accumulation were recorded on Haswell Island, influenced by ornithogenic factors. Unlike most soils in East Antarctica, these soils display a presence of humus-like plasma. The soils studied are characterized by low (or moderate) levels of contamination, according to Igeo (geoaccumulation index); however, an increase in pollutant accumulation rates is observed in ornithogenic habitats and on the surfaces of peat horizons.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>криогенные почвы</kwd><kwd>орнитогенные почвы</kwd><kwd>микроморфология</kwd><kwd>тяжелые металлы</kwd><kwd>Восточная Антарктида</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cryogenic soils</kwd><kwd>ornithogenic soils</kwd><kwd>micromorphology</kwd><kwd>heavy metals</kwd><kwd>East Antarctica</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 24-27-00361,  https://rscf.ru/project/24-27-00361/.</funding-statement><funding-statement xml:lang="en">This study was supported by Russian Science Foundation, grant № 24-27-00361, https://rscf.ru/project/24-27-00361/.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Глазовская М.А.
