Tundra ecosystems have high recourse potential but also are characterized by a low resistance to anthropogenic influences. The aim of our research was to study possible use of organogenic soil horizons, plants and lichens to trace temporary changes in PAH content in south tundra communities under the aerotechnogenic pollution. Monitoring of PAH content was conducted in organogenic soil horizons and plants from lower vegetation layer of southern tundra. Soils and plants were sampled both from the вackground site and from the sites established in 0,5; 1 and 1,5 km north-east from the coal mine “Vorkutinskaya” taking into account the wind rose. The samples were collected at the polluted sites in 2013 and 2015. The model species - lichen Peltigera leucophlebia Nyl., moss Pleurozium schreberi Brid. and dwarf shrub Vaccinium myrtillus L. (leaves). ASE-350 accelerated solvent extraction system (Thermo Fisher Scientific, USA) was used to extract PAHs from plants and soils. PAH content in the sample was determined by HPLC method.13 PAH structures were identified in organogenic horizons, plants and lichens from the sites under study. Coal dust was found to be the main PAH source for soils and plants affected by the mine “Vorkutinskaya”. Light polyarenes made the greatest contribution to the total PAH content. Their proportion remained stable in time at different distances from the mine indicating the constant nature of the contamination. Decrease of PAH content in plants during the two-year period was caused by decrease of mine effect intensity. Plants responded on changes in PAH streams faster than soil organogenic horizons. So, we suppose that plants can be used as better indicators of environmental changes. The largest level of PAH accumulation was revealed for moss Pleurozium schreberi, which due to its wide spread and active PAH accumulation ability can be used to indicate the contamination level in zones affected by coal mining industry.</p></abstract><trans-abstract xml:lang="ru"><p>В связи с быстрым развитием промышленности во всем мире усиливается загрязнение окружающей среды полициклическими ароматическими углеводородами (ПАУ). Тундровые экосистемы наряду с высоким ресурсным потенциалом характеризуются низкой устойчиво-стью к антропогенным воздействиям. Целью исследования было изучение возможностей использования органогенных горизонтов почв, растений и лишайников для диагностики временных изменений содержания ПАУ в фитоценозах южной тундры при аэротехногенном воздействии. Были проведены мониторинговые исследования содержания ПАУ в органогенных горизонтах почв и растениях нижнего яруса южной тундры. Почвы и растения отбирали на фоновом участке и в районе действия угольной шахты «Воркутинская» на расстоянии 0,5; 1,0 и 1,5 км от источника эмиссии с учетом розы ветров в северо-восточном направлении. В зоне действия угледобывающего предприятия отбор был осуществлен в 2013 и 2015 годах. В качестве модельных видов были выбраны лишайник - Peltigera leucophlebia Nyl., мох - Pleurozium schreberi Brid. и листья кустарничка - Vaccinium myrtillus L. Для извлечения ПАУ из почв и растений использовали систему ускоренной экстракции растворителями ASE-350 (Thermo Fisher Scientific, США). Содержание ПАУ в пробе определяли методом ВЭЖХ.В органогенных горизонтах почв, растениях и лишайниках исследованных участков было идентифицировано 13 структур ПАУ. Основным источником ПАУ в почвах и растениях зоны действия шахты Воркутинская, была угольная пыль. В состав ПАУ почв и растений максимальный вклад вносили легкие полиарены, при этом их доля оставалась устойчивой во времени на разном удалении от шахты, что свидетельствует о постоянном характере загрязнения в течение исследованного периода. Уменьшение содержания полиаренов в растениях за двух-летний период свидетельствовало о снижении интенсивности воздействия шахты на изучаемые фитоценозы. Растения быстрее реагировали на изменение потоков полиаренов в тундровых фитоценозах по сравнению с органогенными горизонтами почв, поэтому они могут быть использованы как более чуткие индикаторы изменения состояния окружающей среды. Среди исследованных видов растений наибольшим накоплением полиаренов в условиях загрязнения отличался мох Pleurozium schreberi, который в силу своей широкой распространенности и способности к активной аккумуляции ПАУ может быть использован в целях биоиндикации уровня загрязнения в зонах действия угледобывающей промышленности.</p></trans-abstract><kwd-group xml:lang="en"><kwd>polycyclic aromatic hydrocarbons</kwd><kwd>soil</kwd><kwd>plants</kwd><kwd>temporary changes</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>полициклические ароматические углеводороды</kwd><kwd>почва</kwd><kwd>растения</kwd><kwd>времен-ные изменения</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Abakumov E.V., Lodygin E.D., Gabov D.A., Krylenkov V.A.
