Магнитная восприимчивость – это быстрый, недорогой и надежный метод оценки и мониторинга антропогенного загрязнения почв тяжелыми металлами. Однако важно определить факторы, влияющие на магнитную восприимчивость, прежде чем применять этот метод к экологическим исследованиям. Целью настоящего исследования явилось изучение влияния материнских пород и землепользования на магнитную восприимчивость и концентрации Ni, Pb, Cr, Cd, Cu и Zn, и применения магнитной восприимчивости как показателя антропогенного загрязнения тяжелыми металлами почв г. Вольска Саратовской области Российской Федерации.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Было взято 50 поверхностных образцов почвы (0‐10 см). 1M HNO3 экстрагировали Ni, Pb, Cr, Cd, Cu и Zn определяли методом атомно-абсорбционной спектроскопии. В почве определялась концентрация органического вещества. Измеряли магнитную восприимчивость на низких и высоких частотах (xlf и xhf) и рассчитывали частотно‐зависимую восприимчивость (xfd).</p></sec><sec><title>Результаты</title><p>Результаты. Магнитная восприимчивость варьирует от 1,34 до 29.6 × 10‐7 м3 кг−1. Между Pb и xlf получена положительная сильная корреляция (P=0,01, r=0,55). Существуют значительные взаимосвязи между Pb и xlf, поэтому представляется, что на магнитную восприимчивость существенно повлияла антроогенная деятельность, которая увеличила концентрации Pb в городских почвах.</p></sec><sec><title>Выводы</title><p>Выводы. В исследованных почвах магнитная восприимчивость может использоваться в качестве индикатора антропогенного загрязнения почв тяжелыми металлами.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. Magnetic susceptibility is a fast, inexpensive and reliable technique for estimating and monitoring anthropogenic contamination of soil with heavy metals. However, certain factors affecting magnetic susceptibility need to be determined before applying this technique to environmental studies. The objectives of this study were to investigate: (1) the effect of parent materials and land use on magnetic susceptibility and concentrations of Ni, Pb, Cr, Cd, Cu and Zn; and (2) the possible use of magnetic susceptibility as an indicator of anthropogenic heavy metals contamination of soil in the city of Volsk, Saratov region, Russia.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. Fifty (50) composite surface soil samples (0–10 cm) were selected. 1M HNO3 extractable concentrations of Ni, Pb, Cr, Cd, Cu and Zn were analyzed using atomic absorption spectroscopy. Concentrations of organic matter in the soil were determined. Magnetic susceptibility at low and high frequency (χlf and χhf) were measured and frequency dependent susceptibility (χfd) was calculated.</p></sec><sec><title>Results</title><p>Results. Magnetic susceptibility varied from 1.34 to 29.6 × 10−7 m3 kg−1. A positive strong correlation (P value = 0.01, r = 0.55) was obtained between Pb and χlf. Significant correlational relationships were observed between Pb with χlf, most likely due to significant effects of anthropogenic activities on magnetic susceptibility, therefore enhancing Pb concentrations in urban soils.</p></sec><sec><title>Conclusions</title><p>Conclusions. In the soils studied, magnetic susceptibility could be employed as an indicator of anthropogenic contamination of soil with heavy metals.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Магнитная восприимчивость</kwd><kwd>почва</kwd><kwd>тяжелые металлы</kwd><kwd>никель</kwd><kwd>свинец</kwd><kwd>хром</kwd><kwd>кадмий</kwd><kwd>медь</kwd><kwd>цинк</kwd><kwd>Вольск</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>chromium</kwd><kwd>cadmium</kwd><kwd>copper</kwd><kwd>zinc</kwd><kwd>Volsk</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Президента РФ для поддержки молодых российских ученых (проект МК‐3355.2019.5).</funding-statement><funding-statement xml:lang="en">This research was carried out with funding from a grant by the President of the Russian Federation for the support of young Russian scientists (project MK‐3355.2019.5).</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">Blaha U., Appel E., Stanjek H.
