“…Interestingly, the phytotoxic effects of PHs on maize growth were greatly reduced in the presence of strain MN54 and biochar, indicating the significant role of microbes and biochar addition on plant growth [60]. Because it has been reported that microbes due to their plant growth promoting characteristics (such as P solubilization, ACC-deaminase activity and siderophore formation) enhance plant growth even under pollutant stress or toxic environment [22,61]. Moreover, the presence of active sites and pore spaces on biochar influences the bioavailability of pollutants (and it might be due to the concentration of) in contaminated soil, and found to be effective in improving plant growth under stress conditions [62,63].…”

“…The remarkable reduction in the chlorophyll contents, photosynthetic rate, transpiration rate, and stomatal and sub-stomatal conductance of maize plants was observed under contaminant stress [64]. It could be due to the induced contaminant stress that cause photosynthetic pigments reduction, genetic and transcriptional changes, drought stress, reduced leaves turgor pressure and clogging of stomatal openings by impair thalakoid membrane, mitochondria, vacuoles and ribosomes [56,61,65]. Moreover, the phytotoxic effects of PHs on plant physiology were greatly reduced in the presence of bacteria and biochar, suggesting the inevitable role of contminant-tolerant bacteria and biochar addition on plant physiology [60,61,66].…”

Contamination by petroleum hydrocarbons (PHs) is a great threat to environment due to the higher persistence and bio-toxicity of PHs. Therefore, removal of PHs from contaminated environment and strategies to reduce their toxic effects on living organisms are crucial for environmental safety and human health. The toxic effects of PHs from the polluted soil can be reduced by the addition of microbes and biochar. In this study, a pot trial was carried out to evaluate the effects of sugarcane bagasse (SB) biochar and Bacillus sp. MN54 addition on phytoremediation of PHs and growth of maize (Zea mays L.) in soil artificially contaminated with diesel. Maize seeds were sown in uncontaminated or contaminated (with PHs) soil, treated with biochar and Bacillus sp. MN54. The results revealed that PHs showed significant phytotoxicity to maize plants and the application of strain MN54 and biochar greatly reduced the toxic effects of PHs on plants growth and physiology by increasing the nutrients uptake in PHs contaminated soil. Interestingly, the phytotoxicity of PHs on maize plants was further reduced in the co-supplementation of strain MN54 and biochar. Plants physiological (25–48%) and agronomic (38–47%) attributes were significantly higher as compared to only PHs contaminated soil in the co-supplementation of strain MN54 and biochar. Similarly, nitrogen (41%), phosphorus (43%) and potassium (37%) concentrations were also increased in the co-supplementation of strain MN54 and biochar. Furthermore, maize plants successfully phytoremediate a considerable amount of PHs from soil particularly in the presence of strain MN54 and biochar, and this PHs removal was further enhanced in the co-supplementation of strain MN54 and biochar (i.e., 46% and 77% of initial PHs were removed in unplanted and planted treatments, respectively). The present results indicate that co-supplementation of biochar and Bacillus sp. MN54 could be effective in enhancing the degradation of PHs and improving plant growth in the hydrocarbons contaminated soil.

“…Heavy metals in tailings can cause changes in plant physiology, hydraulics, photosynthesis and induce anatomical changes [ 7 , 8 , 9 , 10 ], which negatively impact the plant survival and remediation processes in contaminated environments. Understanding the enrichment mechanism of heavy metals by plants under stress of tailings can help to design the best phytoremediation scheme and improve the efficiency of phytoremediation [ 11 , 12 ].…”

The physiological mechanisms and phytoremediation effects of three kinds of native quinoa in a desert mining area were studied. We used two different types of local soils (native soil and tailing soil) to analyze the changes in the heavy metal content, leaf physiology, photosynthetic parameters, stem hydraulics, and anatomical characteristics of potted quinoa. The results show that the chlorophyll content, photosynthetic rate, stomatal conductance, and transpiration rate of Kochia scoparia were decreased, but intercellular CO2 concentration (Ci) was increased under heavy metal stress, and the net photosynthetic rate (Pn) was decreased due to non-stomatal limitation. The gas exchange of Chenopodium glaucum and Atriplex centralasiatica showed a decrease in Pn, stomatal conductance (Gs), and transpiration rate (E) due to stomatal limitation. The three species showed a similar change in heavy metal content; they all showed elevated hydraulic parameters, decreased vessel density, and significantly thickened vessel walls under heavy metal stress. Physiological indicators such as proline content and activity of superoxide dismutase (SOD) and peroxidase (POD) increased, but the content of malondialdehyde (MDA) and glutathione (GSH), as well as catalase (CAT) activity, decreased in these three plants. Therefore, it can be concluded that these three species of quinoa, possibly the most dominant 30 desert plants in the region, showed a good adaptability and accumulation capacity under the pressure of heavy metal stress, and these plants can be good candidates for tailings remediation in the Jinchang desert mining area.

“…It was established that HM bioaccumulation in spring barley affected the physiological and ultrastructural changes in plants grown on Technosols. However, the application of biochar impaired the toxic effects of HMs and showed insignificant changes in the maximal quantum yield of photosystem II (one of the most commonly used photosynthesis measuring parameters) compared to plants grown on clean soil [ 74 ]. For example, soil amended with biochar showed a significantly higher biomass of maize than the control and plants grown on non-amended soils [ 75 ].…”

The presence of heavy metals in the soil could impose serious problems on soil-plant systems due to the accumulation of heavy metals in plants. Even vital elements such as Cu and Zn have a toxic effect in the case of excessive intake by living organisms. The present work aimed to investigate the content of loosely bound (exchangeable, complexed, and specifically sorbed) compounds of Cu and Zn and their availability to spring barley (Hordeum sativum distichum) in contaminated Haplic Chernozem soil under the conditions of a model experiment (five approximate permissible concentrations (APC) and 10 APC of metal). Changes in the bioavailability of the metals upon application of carbon sorbents were observed. An increase in loosely bound metal compounds has been shown under conditions of soil contamination with metals (up to 57% of the total content). The increase in the availability of Cu in the soil was mainly due to the formation of complexed metal forms with organic matter (up to 17%). The availability of Zn was found to be associated with an increase in exchangeable (up to 21%) and specifically sorbed compounds (up to 27%). Granular activated carbon (GAC) and biochar have high sorption properties. A decrease in the content of loosely bound compounds of metals was established, especially in the most mobile forms such as exchangeable and complexed forms. The introduction of sorbents into the soil opened up a new venue for binding heavy metals in situ, eventually leading to a decrease in their bioavailability. The inactivation of Cu and Zn in the soil upon the application of sorbents led to a decrease in metal absorption by spring barley. The highest efficiency of biochar application was established at a dose of 2.5% and 5% in soil contaminations of 5 APC and 10 APC of Cu or Zn. The efficiency of the use of sorbents was more influenced by the dose of application than by the type of sorbent. There was no significant difference between biochar and GAC. Stabilization and inactivation of metals may improve soil fertility and plant growth.
