Natural extracts-including organic acids, biosurfactants, and humic substances-are increasingly promoted as sustainable alternatives to synthetic chelators such as EDTA. However, existing reviews largely report removal efficiencies without critically assessing stability, soil dependency, scalability, or regulatory feasibility. This bibliometric-mechanistic synthesis analyzes research published between 2000 and 2025 to evaluate technological maturity, normalization inconsistencies, and long-term durability of natural extract-based remediation. Fewer than 15% of studies progressed beyond laboratory scale, and reported efficiencies (often 70%-90%) were strongly dependent on soil pH, organic matter content, and experimental system (aqueous vs soil-solid matrices). By integrating soil chemistry constraints, thermodynamic stability, and mass balance considerations, this review proposes a comparative framework distinguishing mobilization-based extraction from stabilization-oriented immobilization strategies. A Technology Readiness Level (TRL) perspective and regulatory benchmarking are introduced to assess field applicability. The analysis indicates that while natural extracts demonstrate strong short-term kinetic performance, long-term remobilization risk and multi-season validation remain insufficiently addressed, limiting real-world deployment.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"1-28"},"PeriodicalIF":3.1,"publicationDate":"2026-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147771134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that compared with SPI, DRI could weaken the migration of petroleum to deep soil, enhance the absorption of petroleum pollutants by plant roots, and increase the biomass of ryegrass by 13.793%. In addition, applying surfactants through periodic DRI could improve the utilization efficiency of surfactants in soil and promote the absorption and degradation of petroleum by plants. Under DRI, when the mass ratios of sodium dodecyl benzene sulfonate (SDBS) to Tween 80 were 9:1 and 1:1, the phytoremediation efficiencies were 1.66 times and 1.44 times higher than those in the group without surfactants, respectively. Meanwhile, the phytoremediation efficiency of petroleum was much lower than the degradation efficiency of surfactants, which reduced the secondary pollution caused by surfactants.

This study evaluated the potential of Anoxybacillus caldiproteolyticus to mitigate Cd-induced stress in maize (Zea mays L.) under controlled conditions. Plants were exposed to 100 µM Cd with or without bacterial inoculation (102 CFU mL-1). Cd treatment markedly reduced germination (95.3% to 44.1%), root length (16.24 to 7.06 cm), shoot length (8.69 to 4.23 cm), and dry weight (0.0645 to 0.0543 g), while increasing oxidative damage. Bacterial inoculation partially alleviated these effects, improving germination to 49.6% and increasing root and shoot lengths to 11.0 and 5.37 cm, respectively. Under Cd stress, inoculation significantly enhanced antioxidant enzyme activities, with superoxide dismutase, catalase, and glutathione reductase increasing by 117%, 140%, and 13%, respectively, compared to Cd-treated plants. In contrast, peroxidase activity decreased by 48.57%, likely reflecting reduced hydrogen peroxide levels. These changes were accompanied by reduced reactive oxygen species accumulation and lipid peroxidation. Importantly, Cd accumulation in plant tissues was not significantly altered, indicating that stress mitigation was associated with improved physiological tolerance rather than reduced metal uptake. Overall, A. caldiproteolyticus enhances maize resilience through antioxidant modulation and maintenance redox balance.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"1-9"},"PeriodicalIF":3.1,"publicationDate":"2026-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147771128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

B. subtilis was more effective at lower Cu doses, increasing shoot length by up to 24% and root fresh biomass by 65% compared with the control, while maintaining higher photosynthetic rates and stomatal conductance under Cu stress. In contrast, T. harzianum performed better at higher Cu doses, increasing root dry biomass by more than twofold (112%; p < 0.05) and enhancing Cu accumulation in shoots and roots. It also improved plant water use efficiency under higher metal stress. Under controlled conditions, C. ensiformis tolerated Cu levels up to 250 mg kg-1.

The research details the production and comprehensive characterization of olive kernel biochar, specifically examining its efficacy in capturing diclofenac from aqueous solutions. The biochar's structural and chemical properties were analyzed using advanced techniques, including X-ray diffraction, Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, Brunauer-Emmett-Teller surface area analysis, and scanning electron microscopy. The study systematically investigated the impact pH, biochar dosage, diclofenac concentration, temperature, and time on diclofenac adsorption performance. Under optimized conditions (40 mg/L diclofenac, 1 g/L biochar, 35 °C, and 60 min), the biochar achieved a high removal efficiency of approximately 96%, demonstrating strong adsorption capability. Kinetic modeling suggests that the adsorption process is primarily governed by a pseudo-second-order mechanism, with an excellent correlation coefficient (R2=0.9995). Isotherm analysis indicates that the Temkin model best represents the adsorption behavior, highlighting the energetic heterogeneity of the biochar surface.

Here we report, for the first time, the use of carbonaceous soot derived from candle combustion as a priming agent for a bamboo species, Phyllostachys edulis, under lead stress. Germination parameters, lead accumulation, and antioxidant responses were assessed in primed and non-primed seeds exposed to 0-400 mg L-1 lead. Dynamic light scattering analysis revealed that soot particles had a hydrodynamic diameter of ∼210 nm and a stable zeta potential (-33.5 mV). Scanning electron microscopy confirmed strong adherence of aggregated particles on the seed coat. Soot priming significantly improved germination percentage, reduced mean germination time, and enhanced seedling vigor compared with non-primed seeds across all treatments. X-ray fluorescence analysis showed that priming reduced lead uptake by 24-52%. Primed seedlings exhibited lower catalase, peroxidase, and proline levels, indicating reduced oxidative stress. These improvements are attributed to the soot layer functioning as a physical barrier and metal-adsorptive surface, limiting lead entry during imbibition. Overall, candle-derived soot particles effectively enhance germination under lead stress, offering a simple and inexpensive priming strategy for bamboo establishment in contaminated environments.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"1-15"},"PeriodicalIF":3.1,"publicationDate":"2026-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147771132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
