      <abstract xml:lang="ru">
        <p>Целью данного исследования являлось получение диагностических признаков и критериев распределения тяжелых металлов в техногенно-нарушенных почвах в зоне промышленных объектов в зависимости от их измененных геохимических свойств, позволяющих закреплять химические элементы в ландшафтах (образование геохимических барьеров). На основе геоэкологической оценки выявлены нарушения буферных свойств почв, что проявляется в изменении ионного состава, защелачивании, повышении pH, сульфатно-хлоридном засолении. Это формирует щелочной барьер на пути распространения тяжелых металлов, например, для Cu, Pb, Zn, N, способствует их аккумуляции и последующей концентрации в слое почвы за счет обменных взаимодействий химических элементов с катионами Na+, K+, Cа2+. Насыщение почвенной среды сульфатами также повышает вероятность закрепления металлов в почвенном слое. Показано, что в техногенно-измененных почвах внутрипрофильная почвенная миграция нефтепродуктов (одного из наиболее распространенных загрязнителей промышленных территорий) и химических элементов происходит до глубины 30-50 см, где формируется техногенный барьер в виде нефтепродуктов на глинистом сорбционном слое. Обнаружена прямая зависимость содержания нефтепродуктов в почве от суммы токсичных сульфатных и хлоридных солей. Совокупность выявленных факторов создает условия для взаимообусловленного фиксирования поступающих на поверхность загрязняющих веществ и химических элементов, в том числе тяжелых металлов, формируя спонтанные техногенно обусловленные геохимические барьеры в зоне промышленных производств.</p>

        <p>The purpose of this study was to obtain diagnostic features and criteria for the distribution of heavy metals in technogenically altered soils in the area of industrial facilities, depending on their altered geochemical properties, which make it possible to fix chemical elements in landscapes (the formation of geochemical barriers). On the basis of the geoecological assessment, disturbance of the soil buffer properties, which is reflected in the ionic composition change, alkalization, pH increase, and sulfate-chloride salinization have been revealed. This forms the heavy metals alkaline barrier. For example, in case of Cu, Pb, Zn, and N, it contributes to their accumulation and subsequent concentration in the soil layer due to the exchange interactions between chemical elements and Na+, K+, Ca2+ cations. Soil saturation with sulphates also increases the probability of metals demobilization in the soil layer. It has been shown that intra-sectional soil migration of oil products (one of the most common pollutants of industrial areas) and chemical elements occurs at a depth of 30-50 cm, where the oil products based on a clay sorption layer form a technogenic barrier.</p>
