报告摘要：

She is currently Research Associate Professor and also the head of laboratory “Intellectual Agoecosystems” at South Federal University, Russia. She is also the head of laboratory "Soil health" organized under MEGA Project of Russia. Her current research directions include study of the content of organic pollutants (polycyclic aromatic hydrocarbons, pesticides, polychlorinated biphenyls) in the soil-plant system, study of the toxic effect of organic pollutants on the growth and development of plants as well as transformation and migration of organic pollutants in natural and technogenic landscapes in the south of Russia. She is expert in development of methods for restoring technogenically contaminated soils using innovative microbiological biological products isolated from native soils subject to stress. She was awarded top 100 young scientists of the Southern Federal University in Rostov region of Russia. She is also the winner of competitions under the President of the Russian Federation for state support of young Russian scientists. She has published more than 100 papers in leading Q1 Journals and have h-index of more than 35 with over 5000 citations. She is author of 3 invention patents, 1 utility model patent, 3 computer program patents and 19 databases. She participated in 37 grants (including 15 grants as Principal investigator) from the Ministry of Education and Science of the Russian Federation, the Russian Science Foundation (RSF), the Russian Foundation for Basic Research, the Civil Research and Development Foundation (CRDF), the Project Council of the President of the Russian Federation, and the Innovation Promotion Fund. She also leads the key national project (i.e., Russian strategic leadership program "PRIORITY 2030). She is also involved in several key international cooperation projects with China in NSFC-RSF and also BRICS.

报告人简介：

Benzo[a]pyrene (BaP) is a member of polycyclic aromatic hydrocarbons known as highly persistency and toxicity. Technologies of BaP sorption through solid matrixes has received relatively more attention. The present study was devoted to the phytotesting investigations of two different groups of sorbents, such as carbonaceous, including biochar and granulated activated carbon (GAC), and mineral, including tripoli and diatomite. Evaluation of the BaP removing efficiency was carried out using the phytotesting method with spring barley in Haplic Chernozem contaminated with different levels of contamination (200 and 400 μg kg^-1 BaP). The sorbents efficiency for BaP remediation was estimated in the sorbents doses from 0.5% to 2.5% per kg of soil. It was shown that biochar and GAC decreased the soil toxicity class to a greater extent than mineral sorbents ones. The effect intensified with an increase in applying sorbents doses. The optimal dose of carbonaceous sorbents into the soil contaminated with 200 µg kg^-1 was 1%, decreasing the BaP content up to 57-59% in the soil. Simultaneously, the optimal dose of the mineral sorbents was found to be 1.5%, which decreased the BaP content in the soil up to 41-48%. Increasing the BaP contamination level up to 400 µg kg^-1 showed the necessity of an sorbent dose increasing. In these conditions, among all applied sorbents, only 2% GAC could reduce the soil toxicity class to the normal level. It was shown that BaP tended to migrate from the soil to the roots and further into the vegetative part of spring barley.
