Сопоставить результаты изучения магнитных свойств и концентрации тяжелых металлов в почвах рекреационной зоны «Дубравный лес» города Казани для обоснования применения петромагнитного метода при проведении эколого-геохимических исследований на урбанизированных территориях.Материал и методы. Объектом исследования является почвенный покров в лесном массиве «Дубравный лес», исследованный петромагнитными методами (магнитная восприимчивость, дифференциальный термомагнитный анализ) и методом атомной абсорбционной спектрометрии.Результаты. Согласно результатам проведенных исследований, в изученной светло-серой лесной почве измерения магнитной восприимчивости и концентрации подвижных форм тяжелых металлов не противоречат друг другу и свидетельствуют об отсутствии в исследуемых почвах магнитных минералов и тяжёлых металлов техногенного происхождения.Заключение. Результаты исследований магнитной восприимчивости указывают на отсутствие загрязнения почв соединениями тяжёлых металлов, что было подтверждено по результатам определения подвижных форм тяжёлых металлов атомно-абсорбционным методом.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To compare the results of studying the magnetic properties and concentration of heavy metals in the soils of the Dubravniy Forest recreational zone of Kazan to justify the use of the petromagnetic method in conducting ecological and geochemical studies in urbanised areas.Material and Methods. The object of the study is the soil cover in the "Dubravniy Forest", using petromagnetic methods (magnetic susceptibility, differential thermomagnetic analysis) and atomic absorption spectrometry.Results. According to the results of the studies conducted into the lightgray forest soil, the measurements of magnetic susceptibility and concentration of mobile forms of heavy metals do not contradict each other and indicate the absence of magnetic minerals and heavy metals of technogenic origin.Conclusions. The results of magnetic susceptibility studies indicate the absence of soil contamination with heavy metal compounds, which was confirmed by the results of the determination of mobile forms of heavy metals by the atomic absorption method.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Магнитная восприимчивость</kwd><kwd>почва</kwd><kwd>тяжёлые металлы</kwd><kwd>никель</kwd><kwd>свинец</kwd><kwd>медь</kwd><kwd>цинк</kwd><kwd>Казань</kwd><kwd>Дубравный лес</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Magnetic susceptibility</kwd><kwd>soil</kwd><kwd>heavy metals</kwd><kwd>nickel</kwd><kwd>lead</kwd><kwd>copper</kwd><kwd>zinc</kwd><kwd>Kazan</kwd><kwd>Dubravniy forest</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена за счет средств субсидии, выделенной Казанскому федеральному университету для выполнения государственного задания проект № FZSM-2023-0023 в сфере научной деятельности и за счет средств Программы стратегического академического лидерства Казанского (Приволжского) федерального университета (ПРИОРИТЕТ-2030).</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>This work was funded by the subsidy allocated to Kazan Federal University for the state assignment project № FZSM-2023-0023 in the sphere of scientific activities and has been supported by the Kazan Federal University Strategic Academic Leadership Program (PRIORITY-2030).</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">Еремин В.Н., Шешнев А.С., Решетников М.В., Теслинова О.В.
