The purpose of the present study is estimating the PAH distribution distance in the tundra zone under the impact of thermal power plant (TPP). The study was conducted in the Bolshezemelskaya tundra area of the Vorkuta region (Komi Republic, Russia). The surface accumulation and total content of PAHs in Pleurozium schreberi and organic horizon of tundra surfacegley soils (Stagnic Cambisols) at the background site and sites removed from the TPP at 0.5; 1; 1.5; 3; 5 and 12 km were studied. The PAH content in Pleurozium schreberi under the impact of TPP changes with distance not linearly. The maximum accumulation was noted at 3 km distance, then the content of PAHs decreased and reached a background level of 12 km from the source. The high molecular weight structures seemed to be transported at distance of no more than 3 km and fell down to the moss surface. The light structures could fly further. This fact responded for concentration of heavy and light structures on particles with different diameter. The moss surface at the background and polluted sites did not contain naphthalene. The total polyarene capacity on the moss surface is relatively the same for the background and polluted sites. At 3 km site, there was a sharp increase in the mass fraction of surface PAH by a factor of 3 due to an increase in the mass fraction of 4-5 - nuclear polyarenes. Being contaminated, the moss activates the bioaccumulation processes of PAHs and so transports polyarenes from its surface to inner organs. The exclusion is a site at a distance of 3 km where the proportion of surface accumulation increased with maximum pollution, i.e., PAH ingress into moss decreased. Determined that the dead part of Pleurozium schreberi or the whole plant is to be used for true identification of polyarenes. The changes in polyarene content in organic soil horizons are the same as in Pleurozium schreberi . By the obtained data, PAHs in tundra can move at large distances. The background-like PAH values are estimated for the site as 12 km from the pollution source for Pleurozium schreberi . The background-like PAH values for organic soil horizons are not estimated. The obtained results agree with the cluster analysis data.</p></abstract><trans-abstract xml:lang="ru"><p>Pleurozium schreberi Brid. широко распространен в тундровой зоне и чувствителен к изменениям в составе полициклических ароматических углеводородов (ПАУ) в экосистемах во временном отношении и с расстоянием, поэтому может использоваться в качестве индикатора загрязнения тундровых биоценозов полиаренами. Целью исследования было оценить дальность распространения ПАУ в условиях тундровой зоны на примере воздействия теплоэлектростанции. Работы проводились в Большеземельской тундре в Воркутинском районе Республики Коми. Исследовано поверхностное накопление и общее содержание ПАУ в Pleurozium schreberi и органогенном горизонте тундровых поверхностно-глеевых почв (Stagnic Cambisols) на фоновом участке и удалении от ТЭС 0,5; 1; 1,5; 3; 5 и 12 км. Содержание ПАУ в Pleurozium schreberi под воздействием ТЭС с расстоянием изменялось нелинейно. Максимум накопления отмечен на расстоянии в 3 км, затем содержание ПАУ снижалось и достигало фонового уровня в 12 км от источника. Высокомолекулярные ПАУ перемещались на расстояние до 3 км, где выпадали на поверхность мхов, легкие распространялись дальше, что обусловлено концентрированием тяжелых и легких структур на частицах разного диаметра. На поверхности мха фонового и загрязненного участка не выявлено присутствие нафталина. Суммарное содержание полиаренов на поверхности мхов примерно одинаково. На участке в 3 км отмечено резкое повышение массовой доли поверхностных ПАУ в 3 раза за счет возрастания массовой доли 4-5-ядерных полиаренов. В условиях загрязнения активизировались процессы биоаккумуляции ПАУ, полиарены с поверхности мха активно транспортировались внутрь. Исключением являлся участок в 3 км от ТЭС, где доля поверхностного накопления возрастала при максимальном загрязнении, то есть поступление ПАУ внутрь мха снижалось. Установлено, что для правильной идентификации пиков поступления полиаренов необходимо использовать отмершую часть Pleurozium schreberi или мох в целом. Изменения в содержании полиаренов в органогенных горизонтах почв идентичны с Pleurozium schreberi. Показано, что ПАУ в условиях тундры способны перемещаться на значительные расстояния. Приближенные к фоновым значения содержания ПАУ в Pleurozium schreberi выявлены лишь на расстоянии в 12 км от ТЭС, для органогенных горизонтов почв значения близкие к фоновым не выявлены.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Pleurozium schreberi</kwd><kwd>Stagnic Cambisols</kwd><kwd>Pleurozium schreberi</kwd><kwd>Stagnic Cambisols</kwd><kwd>polyarenes</kwd><kwd>bioaccumulation</kwd><kwd>spread</kwd><kwd>tundra</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>полиарены</kwd><kwd>биоаккумуляция</kwd><kwd>распространение</kwd><kwd>тундра</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was partially supported by the RFBR in frames of the scientific project No. 18-05-60195 (No. TSITiS АААА-А18-118062090029-0) and the state budget theme No. АААА-А17-117122290011-5.</funding-statement><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке РФФИ в рамках научного проекта № 18-05-60195 (№ ЦИТиС АААА-А18-118062090029-0) и госбюджетной темы № АААА-А17-117122290011-5.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Demin BN, Graevskii AP, Demeshkin AS, Vlasov SV.
