Мурманск (ТЭЦ, мусоросжигательный завод, морской торговый порт) проведены исследования содержания тяжелых металлов (Cu, Ni, V, Cd, Zn) в репродуктивных органах рябины Городкова (Sorbus gorodkovii Pojark.). Наиболее загрязнены тяжелыми металлами образцы из окрестностей мусоросжигательного завода. В окрестностях ТЭЦ, работающих на мазуте, выявлены высокие концентрации ванадия (4,2–4,8 мг/кг), превышение ПДК по Cu, Ni, Cd, Zn. Биомониторинг жизнеспособности пыльцы S. gorodkovii показал, что во всех образцах понижено содержание фертильной пыльцы по сравнению с контролем. На пробных площадках Центральной и Южной ТЭЦ доля фертильной пыльцы составляет 35–41 % (в контроле – 72 %). Индуцированная стерильность более чем в 2 раза превышает спонтанную. Высокие концентрации ванадия и других токсичных металлов в выбросах мурманских ТЭЦ оказывают гаметоцидное воздействие на мужской гаметофит S. gorodkovii. Выделены размерные группы фертильных и стерильных пыльцевых зерен по длине полярного диаметра: карликовая, нормальная, гипертрофированная. Показано, что в окрестностях ТЭЦ на угле и мазуте снижается доля фертильной пыльцы нормальных размеров (62–69 %), увеличивается содержание карликовой (16– 18 %) и гипертрофированной (17,4–22,7 %). Стерильные пыльцевые зерна в основном имеют карликовые размеры (63–70 %). Результаты биомониторинга свидетельствуют о том, что ТЭЦ загрязняют городскую среду ванадием и другими токсичными металлами, вызывающими стерилизацию мужских гамет S. gorodkovii. Для улучшения экологической ситуации необходим переход котельных г. Мурманск на использование природного газа.</p></abstract><trans-abstract xml:lang="en"><p>This article investigates the content of heavy metals (Cu, Ni, V, Cd, Zn) in the reproductive organs of the Gorodkov’s rowan (Sorbus gorodkovii Pojark.) growing in the impact zone of environmentally hazardous facilities in Murmansk (CHP plants, waste incineration plant and trade sea port). The samples most contaminated by heavy metals were registered in the vicinity of the incineration plant. High concentrations of vanadium (4,2–4,8 mg/kg) and Cu, Ni, Cd, and Zn exceeding the limits of MPC are revealed in the impact zone of CHP plants operating on fuel oil. Biomonitoring of the viability of S. gorodkovii pollen showed that in all samples, the content of fertile pollen grains was reduced compared to that in the control. At the test sites of the Central and South CHP plants, the proportion of fertile pollen was 35–41 % (compared to 72 % in the control sample). The induced sterility was more than two times higher than the spontaneous sterility. High concentrations of vanadium and other toxic metals in emissions of Heating Plants have a gametocidal effect on the male gametophyte of S. gorodkovii. Groups of fertile and sterile pollen grains were selected according to their size: dwarf, normal, or hypertrophied. In the vicinity of the CHP plants, the proportion of fertile pollen of normal size decreased (62–69 %), whereas the content of dwarf (16–18 %) and hypertrophic pollen (17.4–22.7 %) increased. Sterile pollen grains were mostly dwarf (63–70 %). The results of biomonitoring indicated that CHP plants polluted the urban environment with vanadium and other toxic metals, which caused sterilization of S. gorodkovii male gametes. To improve the ecological situation in Murmansk, it is necessary to switch the thermal stations for the use of natural gas.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биомониторинг</kwd><kwd>Арктика</kwd><kwd>тяжелые металлы</kwd><kwd>Sorbus gorodkovii Pojark.</kwd><kwd>стерильность пыльцы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biomonitoring</kwd><kwd>Arctic</kwd><kwd>heavy metals</kwd><kwd>Sorbus gorodkovii Pojark.</kwd><kwd>pollen sterility</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Воробьев А.Е., Мозолькова А.В.
