“…Soil samples of carbonate Haplic chernozem were saturated with an aqueous CuO solution at doses of 300 and 2000 mg/kg. The dose of 300 mg/kg of soil corresponded to the level of soil contamination in Rostov region [1]. A high level of soil pollution (up to 2000-10000 mg/kg and more) occurs near chemical enterprises, enterprises for non-ferrous metal ores extraction and processing [11].…”

“…The presence of hydrophobic organic pollutants, such as PAHs, often accompanies HM contamination in the soils of industrial areas: tailing facilities, thermal power plants, oil refineries, etc. [1,2,3]. The need to study the mechanism for transformation and degradation of hydrophobic organic compounds in soils contaminated with HM is due to the peculiarities of HM absorption by soils under combined contamination with organic pollutants, which depend on intermolecular interactions of toxicants [4].…”

The environmental contamination by heavy metals (HM) and polycyclic aromatic hydrocarbons (PAH) is often due to exposure to complex sources of industrial and agricultural activities. The aim of the work is to evaluate the combined effect of CuO and benzo(a)pyrene (BaP) on the state of spring barley plants. It was established that the soil combined pollution by CuO and BaP has a negative effect on all morphobiometric parameters of barley. The most sensitive indicators of combined contamination are the length of the roots, the mass of 1000 grains and the yield of barley.

“…It is well known that the pH and OC affect not only the physicochemical possessions of the soil but also the binding as well as retention capacity of HMs (Liu et al 2014). In this saline habitat, high value of pH can be regarded as an indicator for a potential risk of HM pollution because under high pH conditions, HM (like Zn, Fe) become less mobile and more efficiently retained in the soil (Zeng et al 2011;Minkina et al 2017). Iron content indicated its greater concentration than that of Mn and other HMs in this habitat.…”

Assessment of phytoremediation capacity of three halophytes: Suaeda monoica, Tamarix indica and Cressa critica

Halophyte is a distinctive group of plants that can survive, even well flourish, at a concentration of Na + and Cl − ions along with heavy metals that would be lethal to most of the agricultural crop species. These capabilities make certain halophytes good contenders for phytoremediation through phytoextraction or phytostabilization of the salt and heavy metals (HMs) in polluted soils. Thus, the present study elucidates the phytoextraction capacity of three halophytes (Suaeda monoica, Tamarix indica and Cressa critica) growing in saline soil (EC 112 ds m −1), with higher level of HMs rather than a cultivated soil. The accumulation of ions in above-ground tissue was determined in the all three studied plants, considering the fact that maintaining a stable cytosolic Na + /K + ratio has become a crucial salinity tolerance mechanism. The higher salinity of soil resulted in high level of Na + ions in leaves, increased synthesis of osmolyte components and robust antioxidant activities to combat the oxidative stress. As whole, changes in cellular metabolites were determined by using FT-IR spectroscopy, evident as differential FT-IR profiles in both leaves and stem specific to these metabolites. The considerable amounts of HMs accumulation including Zn, Fe, Mn, Cu, Cr, and Cd with highest being Fe in above-ground tissue of all three studied halophytes were obtained. These preliminary findings represent S. monoica, T. indica and C. cretica as potent phytoremediation plant using phytosequestration to accumulate HMs. The present study project a light on the use of these three plants in reclamation of degraded saline soils.

“…Присутствие гидрофобных органических загрязняющих веществ, таких как ПАУ, часто сопутствует загрязнению ТМ в почвах промышленных территорий: хвостохранилища, тепловые электростанции, нефтеперерабатывающие комбинаты и т.п. [2,3,4]. Необходимость изучения механизма трансформации и деградации гидрофобных органических соединений в почвах, загрязненных ТМ, обусловлена особенностями поглощения ТМ почвами при сочетанном загрязнении с органическими поллютантами, которые основаны на межмолекулярных взаимодействиях токсикантов.…”
