The studies were carried out under the conditions of a vegetation experiment, in which the processes of bioremediation of soils contaminated with various oil products were simulated using microbiodestructors and humic preparations (“Ekorost” and “Gumi”). It has been established that the implementation of bioremediation measures using microbio-destructors does not allow for complete detoxification of soil contaminated with various oil products. The manifestation of detoxifying properties of humic preparations in relation to oil-hydrocarbon pollution of soils during their bioremediation was revealed. The severity of these properties varies and depends on the type of oil-polluting product, its concentration, as well as on the properties of the preparations themselves.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Приводятся результаты экспериментальных исследований по оценке фитотоксичности почв, загрязненных нефтепродуктами различных фракций (бензин, дизельное топливо, мазут), в процессе их микробиологической ремедиации при внесении гуминовых препаратов. Исследования осуществлялись в условиях вегетационного эксперимента, в котором моделировались процессы биоремедиации почв, загрязненных различными нефтепродуктами, с применением микробиодеструкторов и гуминовых препаратов («Экорост» и «Гуми»). Установлено, что биоремедиационные мероприятия с использованием микробиодеструкторов не позволяют осуществить полную детоксикацию почвы, загрязненной различными нефтепродуктами. Выявлено проявление гуминовыми препаратами детоксифицирующих свойств в отношении нефтеуглеводородного загрязнения почв при их биоремедиации. Выраженность этих свойств варьирует и зависит от типа нефтепродукта-загрязнителя, его концентрации, а также от свойств самих препаратов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>soil pollution</kwd><kwd>petroleum products</kwd><kwd>bioremediation</kwd><kwd>microbiodestructors</kwd><kwd>phytotoxicity</kwd><kwd>humic preparations</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>загрязнение почвы</kwd><kwd>нефтепродукты</kwd><kwd>биоремедиация</kwd><kwd>микробиодеструкторы</kwd><kwd>фитотоксичность</kwd><kwd>гуминовые препараты</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by a grant from the RFBR and the Government of the Ryazan Region No. 18-45-623003 r_mol_a “Investigation of the effect of biosurfactants based on humic substances on the processes of microbiological remediation of natural environments contaminated with oil products”.</funding-statement><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке гранта Российского фонда фундаментальных исследований и Правительства Рязанской области № 18-45-623003 р_мол_а «Исследование влияния биоПАВ на основе гуминовых веществ на процессы микробиологической ремедиации природных сред, загрязненных нефтепродуктами».</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Liu Q, Tang J, Gao K, Giesy JP.
