Abstract

Актуальность. Несмотря на значительное количество работ по исследованию загрязнения объектов окружающей среды полиаренами, недостаточно сведений о накоплении полициклических ароматических углеводородов и, в частности, наиболее токсичного бенз[а]пирена разными видами травянистых растений, что обусловливает актуальность исследований в данном направлении. Проведено изучение распределения бенз[а]пирена по органам растений и органогенным горизонтам почв зоны воздействия Новочеркасской ГРЭС. Цель: выявить закономерности накопления бенз[а]пирена в растениях разных видов и органогенном горизонте почв степных фитоценозов в зависимости от удаления от Новочеркасской ГРЭС. Объекты. В зоне действия Новочеркасской ГРЭС был проведен отбор проб надземной и корневой частей растений и подстилающих их органогенных горизонтов почв на глубину 0-20 см. Для исследования на мониторинговых площадках нами были выбраны доминантные виды травянистых растений: амброзия полыннолистная (Ambrosia artemisiifolia L.), полынь австрийская (Artemisia austriaca Jack.), тысячелистник благородный (Achillea nobilis L), цикорий обыкновенный (Cichorium intybus L.), пижма обыкновенная (Tanacetum vulgare L.), пырей ползучий (Elytrigia repens (L.) Nevski.). Также были исследованы злаковые культуры: овсюг (Avena fatua), пшеница (Triticum aestivum L.), овес (Avena sativa L.), овсяница валлисская, или типчак (Festuca valesiaca L.), тростник обыкновенный (Phragmites australis L.), мятлик луговой (Poap retense L.). Методы. Содержание бенз[а]пирена в образцах растений определяли модифицированным методом омыления. Модификация предполагает замену трехразовой экстракции этоксиэтаном, являющимся прекурсором, на н-гексан. Извлечение поллютанта растворителем проводили после удаления мешающих липидных макрокомпонентов растений, предварительно подвергая кипячению образец в 2-% растворе гидрооксида калия. Определение концентрации бенз[а]пирена осуществляли на хроматографе Agilent 1260 с флуориметрическим детектором. Результаты. На основании кластерного анализа выявлены три группы травянистых растений по уровню содержания бенз[а]пирена: слабого, среднего и активного накопления. Максимальные уровни накопления бенз[а]пирена выявлены для типчака, минимальные для амброзии. Установлено, что массовая доля бенз[а]пирена в почвах и растениях закономерно снижалась по мере удаления от предприятия. Максимальное загрязнение было выявлено по трансекте генерального направления, в 1,6 км от источника. Наименее загрязненными были площадки, заложенные в восточном направлении. Исследование накопления бенз[а]пирена в разных органах растений показало, что наибольшим загрязнением отличались корни всех исследованных видов. Массовая доля бенз[а]пирена в органогенном горизонте почв значительно превышала его содержание в растениях разных видов. The relevance of the research. Despite a significant amount of research of environmental pollution by polyarenes, there is insufficient information on accumulation of polycyclic aromatic hydrocarbons, and in particular the most toxic benzo[a]pyrene, by various types of herbaceous plants, which determines the relevance of research in this direction. The distribution of benzo[a]pyrene over plant organs and organogenic horizons of soils in the Novocherkassk Power Station effect zone was studied. The main aim was to study the accumulation of benzo[a]pyrene in plants of different species and the organogenic soil horizon of steppe phytocenoses depending on the distance from Novocherkassk Power Station. Objects. In the coverage area of the Novocherkassk Power Station, the samples of the aerial and root parts of plants and the underlying soil horizons of the organogenic layers were taken to a depth of 0-20 cm. For the study on monitoring sites, dominant species of herbaceous plants: ragweed (Ambrosia artemisiifolia L.), Austrian wormwood (Artemisia austriaca Jack.), noble yarrow (Achillea nobilis L), common chicory (Cichorium intybus L.), common tansy (Tanacetum vulgare L.), creeping wheatgrass (Elytrigia repens (L.) Nevski.) were selected. The cereals: oatmeal (Avena fatua), wheat (Triticum aestivum L.), oats (Avena sativa L.), Wallis fescue or fescue (Festuca valesiaca L.), common reed (Phragmites australis L.), meadow bluegrass (Poap retense L.) were studied as well. Methods. The content of benzo[a]pyrene in plants was determined by the standard method RD 52.10.556-95 in a modification that allows removing interfering lipid macrocomponents of plants by saponification (saponification method). When benzo[a]pyrene was determined by the method of saponification, the saponifiable lipid fraction was initially removed in the samples by boiling the plant sample in an alcohol solution of alkali, followed by threefold extraction of benzo[a]pyrene with hexane. The basis for determination of benzo[a]pyrene in soils is the PND 16.1:2:2. 2:3. 39-03 technique. Quantitative determination of benzo[a]pyrene in the extract was carried out by high performance liquid chromatography. The results. Based on cluster analysis, three groups of herbaceous plants were identified by the level of benzo[a]pyrene content: weak, medium, and active accumulation. The maximum levels of benzo[a]pyrene accumulation were found for fescue, and the minimum for ragweed. It was found that the mass fraction of benzo[a]pyrene in soils and plants naturally decreased with distance from the enterprise. Maximum pollution was detected by the transect of the general direction, 1,6 km from the source. The least polluted sites were laid in the eastern direction. A study of polyarenes accumulation in different organs of plants showed that the roots of all the species studied differed the greatest pollution. The mass fraction of benzo[a]pyrene in the organogenic horizon of soils significantly exceeded its content in plants of various species.

Abstract

The research of the fundamentals of the behavior of behavior in the soil–plant system during their co-contamination is of high interest because of the absence of technologies for the creation of effective, environmentally friendly and cost-effective remediation methods, as well as integrated systems for predicting the quality of soils co-contaminated with HMs and PAHs. The unique model vegetation experiment was studied with Haplic Chernozem contaminated by one of the priority organic toxicants, benzo[a]pyrene (BaP), applied alone and co-contaminated with Cu with the subsequent vegetation of tomato (Solanum lycopersicum) and spring barley plants (Hordeum sativum Distichum). Biochar obtained from sunflower husks was used as a sorbent for the remediation of the contaminated soil. It was established that by increasing the BaP amount applied to the soil, the rate of BaP degradation improved. The effect was enhanced in the presence of biochar and decreased in the case of joint co-contamination with Cu, which is especially expressed for the soil of tomato plants. The half-degradation time of the BaP molecule varied from 8 up to 0.2 years for tomatoes and barley. [ABSTRACT FROM AUTHOR]

Abstract

16th International Multidisciplinary Scientific Geoconference (SGEM 2016) -- JUN 30-JUL 06, 2016 -- Albena, BULGARIA ?????????, ?????/0000-0002-8603-4038; Turina, Irina/0000-0003-4433-4849; Minkina, Tatiana/0000-0003-3022-0883 WOS: 000391653500006 The purpose of the research is investigation of accumulation, migration and transformation features of benzo[a]pyrene (BaP) in the soil-plant system. The new original method of the BaP analysis by subcritical water extraction was used for BaP extraction from soil and plant samples of the unique model experiment with the ordinary carbonate chernozem, polluted by different doses of BaP. Sampling of soil (carbonate heavy loamy chernozem, virgin, 0-20 cm topsoil) was carried out in the Persianovskaya steppe of the Rostov region (South of Russian Federation) located far from possible contamination sources. As a result the constants of BaP half-destruction (T50) and coefficients of BaP accumulation in a pollutant plants were calculated in the chernozem soil at different levels of pollution. Correlation dependences of these indicators on initial concentration of BaP in the soil were established. Further these characteristics will allow to create model of transformation of BaP and other the polycyclic aromatic hydrocarbons (PAHs) in chernozem soils of a steppe zone. The main features of accumulation, migrations and transformations of BaP under natural conditions were conducted. This model can be used for forecasting of a situation in various regions subject to pollution by such dangerous organic pollutant as PAHs, and also will allow to estimate probability of PAHs accumulation in soil-plant system under technogenic pressure and their involvement in a food chain.

Abstract

The aim of this article is assessment biochar bioremediation potential in the benzo[a]pyrene artificially contaminated Haplic Chernozem with various doses of benzo[a]pyrene (200, 400 and 800 μg/kg) equivalent to 10, 20 and 40 levels of maximal permissible concentrations (MPC) and 1-5% biochar amendment. The main subject of this study is to research the most effective dose of biochar amendment in benzo[a]pyrene contaminated soil in a model experiment with chernozem. The content of benzo[a]pyrene in soil was determined by using new ecologically friendly method of subcritical water extraction instead of traditional methods based on a large amount of organic solvents. The experiment was carried out with Haplic Chernozem, virgin, taken from the upper 0-20 cm layer of soil in the State Soil Preserve "Persianovsky preserved steppe" of Rostov region (south of Russian Federation) located far from contaminated sources. This soil revealed the following physical and chemical characteristics: Corg 3.4%; pH 7.3; cation exchange capacity (CEC) 37.1 mMol(+)/100g; content of CaCO3 0.1%; physical clay 53.1% and clay 32.4%. The experimental soil samples were incubated outdoor during 4 months. The express-method of subcritical water extraction was used for benzo[a]pyrene extraction from samples. Thus, the influence of different doses of biochar was revealed on the dynamics of benzo[a]pyrene content in soils. The influence of natural and technogenic factors on the accumulation and distribution of benzo[a]pyrene in soils has been established. [ABSTRACT FROM AUTHOR]

Abstract

This article is devoted to the assessment of toxic effect of benzo[a]pyrene (BaP) on spring barley (Hordeum sativum distichum) grown in background control Haplic chernozem and that spiked with various doses of BaP (20, 200, 400 and 800 µg/kg) equivalent to 1, 10, 20 and 40 levels of maximal permissible concentrations (MPC). The experimental soil samples were planted every spring and incubated outdoor during 4 years. During the experimental time (almost 4 years), concentrations of BaP decreased by 80-87% in the soil samples spiked with high doses, while only about 41% BaP degraded in the soil with lowest dose of the pollutant. Concentration of BaP in the background and ACN-control soils decreased finally by about 54 and 60% respectively that is also much less compared to highly contaminated soils. Substantial amounts of BaP were accumulated in the spring barley plants. Its concentrations in roots and vegetative part depended on the initial BaP contamination and reduced simultaneously with diminish of BaP concentration in the related spiked samples. The coefficients BaP bioaccumulation in roots and vegetative part fluctuated within 0.035÷0.065 and 0.015÷0.025 respectively at the 1st season and reduced about twice to the end of the experiment. Meantime those values in control soils vice-versa were low at the beginning (0.03 and 0.01 respectively) but increased twice to the 4th season that is explained by the change of BaP availability in the soils.
