Interactive effect of biochar and compost with Poaceae and Fabaceae plants on remediation of total petroleum hydrocarbons in crude oil contaminated soil

Metal(loid) tolerance, accumulation, and phytoremediation potential of wetland macrophytes for multi-metal(liod)s polluted water.

“…Phytoremediation generally enjoys the status of being a green and eco-friendly method for the treatment of contaminated soils, sediments and/or waters (Yousaf et al 2022). However, the technical and economic potential of phytoremediation and the speci c phytoremediation strategy (e.g., stabilization, accumulation, extraction, etc.)…”

Evaluation of Biostimulation, Bioaugmentation, and Organic Amendments Application on the Bioremediation of Recalcitrant Hydrocarbons of Soil

“…Traditionally, three bioremediation strategies for TPHs pollution have been used: natural attenuation, biostimulation, and bioaugmentation (Khan et al, 2016b;Hussain et al, 2022). Natural attenuation, one of the most straightforward ways to treat soil pollution, uses the intrinsic degradation capability of the autochthonous microorganisms to degrade contaminants; however, it has a long period to achieve successful results due to the low population size of indigenous degrading microorganisms, or the adverse soil physical-chemical conditions (Yousaf et al, 2022). In the present study, control samples did not significantly change TPHs concentrations, neither aliphatic nor aromatic fractions, even though soil incubation was carried out under optimal temperature, aeration, and available water for microbial growth.…”

“…Despite numerous studies focused on decontamination strategies, it remains crucial to gain new, innovative, and sustainable techniques to reduce, degrade, and remove diverse pollutants in soils, sediments, and water bodies. Conventional technologies for cleaning-up contaminated soils (excavation, landfilling, and soil washing) and waters (treatment with activated carbon or ion exchange resins) are generally energy-intensive, expensive, time-consuming, and waste-producing (Yousaf et al, 2022). These technologies are not efficient for treating moderate to low-level polluted sites, which still pose human health and environmental risk.…”

“…An increased pollutant load can delay the profits of remediation using microorganisms (Hussain et al, 2022). Apart from this, the hydrocarbon-impacted soil remediation process is highly dependent on aeration, nutrients content, organic matter, CN ratio and the presence of the hydrocarbon-degrading microbial population (Yousaf et al, 2022). Even if all these factors are maintained to optimal, the biggest challenge to treatment is associated with aged or weathered hydrocarbon-contaminated soils.…”

Performance evaluation of rhamnolipids addition for the biodegradation and bioutilization of petroleum pollutants during the composting of organic wastes with waste heavy oil

“…studied the petroleum-contaminated soil composting with biogas slurry and found that the composting process could significantly improve the degradation of total petroleum hydrocarbons in petroleum-contaminated soil, and the product is less toxic to plants ( Xi et al., 2020 ). Some researchers also added mature compost (composting product) to the soil contaminated by petroleum hydrocarbons and found that the total petroleum hydrocarbon content of the soil decreased after adding the compost product ( Yousaf et al., 2022 ). However, the researchers also emphasized that the use of compost alone had limited the degradation of petroleum hydrocarbons in the soil.…”
