“…The biomass values of P. vulgaris at physiological maturity ( Table 5 ) indicate healthy growth only in agricultural soils without hydrocarbons ( Figure 1 ). This result supports the fact that phytoremediation of any agricultural soil could be applied to soils contaminated with relatively high concentration of hydrocarbons such as those of WMO, if its biorecovery begins with biostimulation followed by bioaugmentation, where X. autotrophicus can decrease WMO concentration and finally when P. vulgaris is enhanced with X. autotrophicus, a facultative endophyte able to invade roots to transform organic compounds of photosynthesis into phytohormones [ 15 , 25 ]. X. autotrophicus induces a root system in P. vulgaris with a greater capacity for the phytodegradation of WMO and simultaneously optimizes the absorption of minerals [ 26 , 27 ].…”

“…The growth of P. vulgaris at seedling level ( Table 4 ) showed its sensitivity to WMO phytotoxicity; this response of P. vulgaris is used as an indicator of the degree of recovery or contamination of the soil to the concentration of WMO [ 15 , 23 ]. Thus, if the WMO concentrations in soil decrease, P. vulgaris starts growth with a pattern analogous to that observed when the soil is not contaminated with WMO in part because bioaugmentation with X. autotrophicus cimulation, bioaugmentation, and phytoremediaauses oxidation of aromatic hydrocarbons and, subsequently, reduction of the concentration of WMO as reported in the literature [ 17 , 19 , 24 ].…”

“…Subsequent bioaugmentation occurs when the soil is inoculated with Xanthobacter autotrophicus, a facultative endophytic bacteria that uses WMO as a source of carbon and energy to remove WMO [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. Biostimulation and bioaugmentation are strategies for reducing WMO and phytoremediation by Phaseolus vulgaris and X. autotrophicus [ 17 ] to ensure that the final WMO concentration is below the limit accepted by NOM-138 [ 4 ].…”

Agricultural soil contamination by waste motor oil (WMO) is a worldwide environmental problem. The phytotoxicity of WMO hydrocarbons limits agricultural production; therefore, Mexican standard NOM-138-SEMARNAT/SSA1-2012 (NOM-138) establishes a maximum permissible limit of 4400 ppm for hydrocarbons in soil. The objectives of this study are to (a) biostimulate, (b) bioaugment, and (c) phytoremediate soil impacted by 60,000 ppm of WMO, to decrease it to a concentration lower than the maximum allowed by NOM-138. Soil contaminated with WMO was biostimulated, bioaugmented, and phytoremediated, and the response variables were WMO concentration, germination, phenology, and biomass of Phaseolus vulgaris. The experimental data were validated by Tukey HSD ANOVA. The maximum decrease in WMO was recorded in the soil biostimulated, bioaugmented, and phytoremediated by P. vulgaris from 60,000 ppm to 190 ppm, which was considerably lower than the maximum allowable limit of 4400 ppm of NOM-138 after five months. Biostimulation of WMO-impacted soil by detergent, mineral solution and bioaugmentation with Xanthobacter autotrophicus accelerated the reduction in WMO concentration, which allowed phytoremediation with P. vulgaris to oxidize aromatic hydrocarbons and recover WMO-impacted agricultural soil faster than other bioremediation strategies.

“…Polluting gases come in a diverse range, which can generally be categorized into five groups: (1) sulfur-containing compounds, such as H 2 S, SO 2 , and thiols [47,48]; (2) nitrogencontaining compounds, including ammonia and amine substances [49]; (3) halogens and their derivatives, such as chlorine gas and halogenated hydrocarbons [50][51][52]; (4) hydrocarbons and aromatic hydrocarbons [53,54]; (5) oxygen-containing organic compounds, like alcohols, phenols, and aldehydes [55]. Dincer et al [56] measured the concentrations of VOCs at a landfill site in Izmir, Turkey, where they identified a total of 48-53 VOCs, as depicted in Figure 3.…”

Volatile organic compounds (VOCs), as a primary pollutant in industrial-contaminated sites or polluted soils, cause severe damage to the soil. Therefore, a comprehensive understanding of the transport of VOCs in soil is imperative to develop effective detection means and removal methods. Among them, biochar possesses potential advantages in the adsorption of VOCs, serving as an effective method for removing VOCs from soil. This review provides an overview of the VOCs within soil, their transport mechanisms, monitoring technology, and removal approach. Firstly, the historical development of the VOC migration mechanism within the capping layer is described in detail. Secondly, the in situ monitoring techniques for VOCs are systematically summarized. Subsequently, one of the effective removal technologies, a capping layer for polluted sites, is simply introduced. Following this, the potential application of a biochar-modified capping layer for the removal of VOCs is comprehensively discussed. Finally, the major challenges in the field and present prospects are outlined. The objective of this study is to furnish researchers with a foundational understanding of VOCs, their relevant information, and their removal approach, inspiring environmental protection and soil pollution control.

“…As for humans and animals, long-term contact with and/or intake of 1,2dichloroethane-containing groundwater could cause cranial nerve injury, gene mutations and cancer [82,83]. Once 1,2-dichloroethane-containing groundwater enters into and accumulates in plants/crops, the photosynthesis and growth of the plants/crops will be inhibited [84].…”

The Junggar Basin in Xinjiang is located in the hinterland of Eurasia, where the groundwater is a significant resource and has important ecological functions. The introduction of harmful organic pollutants into groundwater from increasing human activities and rapid socioeconomic development may lead to groundwater pollution at various levels. Therefore, to develop an effective regulatory framework, establishing a list of priority control organic pollutants (PCOPs) is in urgent need. In this study, a method of ranking the priority of pollutants based on their prevalence (Pv), occurrence (O) and persistent bioaccumulative toxicity (PBT) has been developed. PvOPBT in the environment was applied in the screening of PCOPs among 34 organic pollutants and the risk assessment of screened PCOPs in groundwater in the Junggar Basin. The results show that the PCOPs in groundwater were benzo[a]pyrene, 1,2-dichloroethane, trichloromethane and DDT. Among the pollutants, benzo[a]pyrene, 1,2-dichloroethane and DDT showed high potential ecological risk, whilst trichloromethane represented low potential ecological risk. With the exception of benzo[a]pyrene, which had high potential health risks, the other screened PCOPs had low potential health risks. Unlike the scatter distribution of groundwater benzo[a]pyrene, the 1,2-dichloroethane and trichloromethane in groundwater were mainly concentrated in the central part of the southern margin and the northern margin of the Junggar Basin, while the DDT in groundwater was only distributed in Jinghe County (in the southwest) and Beitun City (in the north). Industrial and agricultural activities were the main controlling factors that affected the distribution of PCOPs.
