Орлан – белохвост – редкий, крупный вид хищных птиц. Для восстановления вида создаются в зоологических учреждениях резервные популяции. Птицы имеют достаточно высокий уровень обмена веществ и чувствительны к загрязнителям, поэтому необходимо проводить мониторинг среды содержания и оценивать количественное поступление химических веществ в организм животных.</p><p>Целью исследования явилось изучение влияния загрязнения окружающей среды на накопления тяжелых металлов (цинка, меди, железа, свинца, кадмия и мышьяка) орланами - белохвостыми, проживающих в зоологических учреждениях городов Москвы, Иваново и Ярославля.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Оценка уровня концентрации металлов проводилась с помощью разработанных центильных шкал, которые планируется применять для оценки факторов развития паранеопластических офтальмопатий.</p></sec><sec><title>Результаты</title><p>Результаты. При изучении различий кумуляции тяжелых металлов в перьях орланов - белохвостых установлено достоверное увеличение концентрации кадмия стержне в 3,64 раза, что свидетельствует о его внешнем поступлении. В перьях самцов, по сравнению с самками, выявлено достоверное (р &lt; 0,05) увеличение содержания Cu в 13,98 раза, Zn – в 8,41 раза. У самок установлено достоверное увеличение концентрации Cd в 1,60 раза, As - в 12,18 раза. Выводы. Выявлена достоверная средняя прямая связь между уровнем Zn и Fe, Cu и Pb, Cd и As, что свидетельствует о взаимной симбатности между этими металлами в организме животных. Между Zn и As определено антагонистическое совместное накопление. Средние концентрации Zn, Cu, Pb и Cd установлены у 50 % экземпляров орланов, Fe и As — у 62,5 % от общего количества изученных птиц. В исследуемой выборке животных выявлена тенденция к увеличению накопления Fe и As.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The white-tailed eagle is a rare, large species of bird of prey. To restore the species, reserve populations are created in zoological institutions. Birds have a fairly high level of metabolism and are sensitive to pollutants, so it is necessary to monitor the environment and evaluate the quantitative intake of chemicals into the animal organism. </p></sec><sec><title>Purpose</title><p>Purpose. The aim of the study was to study the effect of environmental pollution on the accumulation of heavy metals (zinc, copper, iron, lead, cadmium and arsenic) by white-tailed eagles living in zoological institutions in the cities of Moscow, Ivanovo and Yaroslavl. </p></sec><sec><title>Materials and Methods</title><p>Materials and Methods. The assessment of the level of metal concentration was carried out using the developed centile scales, which are planned to assess the development factors of paraneoplastic ophthalmopathies. </p></sec><sec><title>Results</title><p>Results. When studying the differences in the accumulation of heavy metals in the feathers of white-tailed eagles, a significant increase in the concentration of cadmium in the rod by 3.64 times was found, which indicates its external intake. In the feathers of males, compared with females, a significant (p &lt; 0.05) increase in the content of Cu by 13.98 times, Zn - by 8.41 times was revealed. In females, a significant increase in the concentration of Cd by 1.60 times, As - by 12.18 times was found. </p></sec><sec><title>Conclusions</title><p>Conclusions. A reliable average direct relationship between the level of Zn and Fe, Cu and Pb, Cd and As was revealed, which indicates the mutual symbation between these metals in the animal body. Between Zn and As defined antagonistic joint accumulation. The average concentrations of Zn, Cu, Pb and Cd were found in 50% of the specimens of sea eagles, Fe and As in 62.5% of the total number of birds studied. In the studied sample of animals, a tendency to an increase in the accumulation of Fe and As was revealed.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>поллютанты</kwd><kwd>токсиканты</kwd><kwd>тяжелые металлы</kwd><kwd>перья</kwd><kwd>орлан-белохвостый</kwd><kwd>биосубстраты</kwd><kwd>паранеопластические офтальмопатии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pollutants</kwd><kwd>toxicants</kwd><kwd>heavy metals</kwd><kwd>feathers</kwd><kwd>white-tailed eagle</kwd><kwd>biosubstrates</kwd><kwd>paraneoplastic ophthalmopathies</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">Еськов, Е.
