Представлены материалы по распределению тяжёлых металлов в органах лиственницы Сукачёва (Larix sukaczewii Dyl.) в условиях загрязнения промышленного центра г. Стерлитамака.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. С помощью атомно-абсорбционного метода определялось содержание меди, свинца и кадмия в почвенном покрове, хвое, ветвях и корнях у здоровых и ослабленных деревьев лиственницы.</p></sec><sec><title>Результаты</title><p>Результаты. В условиях промышленного загрязнения относительное жизненное состояние насаждений лиственницы оценивается как ослабленное (LN = 74,25%), в зоне контроля как здоровое (LN = 84,75%). У ослабленных деревьев с увеличением концентрации металлов в почвах и корнях отмечается увеличение концентрации металлов в надземных органах, а у здоровых деревьев больше депонируется в корнях.</p></sec><sec><title>Обсуждение</title><p>Обсуждение. Высокое содержание тяжёлых металлов в почве приводит к перераспределению корненасыщенности почвы поглощающими корнями, что проявляется в снижении биомассы корней в верхних, наиболее загрязнённых слоях почвы, а также негативно отражается на жизненном состоянии древостоев за счёт уменьшения густоты кроны и увеличения на стволах доли мёртвых и отмирающих ветвей.</p></sec><sec><title>Выводы</title><p>Выводы. В условиях загрязнения лиственница способна активно поглощать и депонировать значительное количество Cu, Cd и Pb, тем самым ограничивая их распространение в окружающей среде.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Materials on the distribution of heavy metals in the organs of Larix sukaczewii Dyl. are presented in the conditions of the pollution of the industrial center of Sterlitamak.</p></sec><sec><title>Material and methods</title><p>Material and methods. Using the atomic absorption method, the content of copper, lead, and cadmium in the soil cover, needles, branches, and roots was determined in healthy and weakened larch trees.</p></sec><sec><title>Results</title><p>Results. Under conditions of the industrial pollution, the relative life condition of larch stands is estimated as «weakened» (LN = 74.25%), in the control zone as «healthy» (LN = 84.75%). Weakened trees with increasing metal concentrations in soils and roots show an increase in the concentration of metals in the aerial organs, and in healthy trees, it is more deposited in the roots. </p></sec><sec><title>Discussion</title><p>Discussion. The high content of heavy metals in the soil leads to a redistribution of the root-saturation of the soil with absorbing roots, which is manifested in a decrease in the biomass of the roots in the upper, most contaminated soil layers, and also negatively affects the vital state of the trees by decreasing the density of the tree crown and increasing the share of dead and dying branches on the trunks.</p></sec><sec><title>Conclusion</title><p>Conclusion. Under conditions of contamination, larch is able to actively absorb and deposit a significant amount of Cu, Cd, and Pb, thereby limiting their distribution in the environment.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>лиственница Сукачёва</kwd><kwd>медь</kwd><kwd>свинец</kwd><kwd>кадмий</kwd><kwd>относительное жизненное состояние</kwd><kwd>поглощающие корни</kwd><kwd>промышленное загрязнение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Larix sukaczewii Dyl</kwd><kwd>copper</kwd><kwd>lead</kwd><kwd>cadmium</kwd><kwd>relative life state</kwd><kwd>absorbing roots</kwd><kwd>industrial pollution</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">Коломыц Э.Г., Розенберг Г.С., Глебова О.В., Сурова Н.А., Сидоренко М.В., Юнина В.П.
