This study was designed to discover the potential of polyethylene glycol (PEG) seed priming in alleviating NaF stress in R. sativus. During this study, seeds of R. sativus were divided into two groups: primed seeds and nonprimed seeds. Polyethylene glycol was used at four different concentrations (PEG-10%, PEG-20%, PEG-30%, and PEG-40%) for seed priming, and PEG-30% proved to be the most effective against the adverse effects of NaF. Compared with nonprimed plants, plants primed with PEG-30% showed increase in various growth parameters, including shoot length (51.13%), root length (46.06%), shoot fresh weight (58.18%), shoot dry weight (86.62%), root fresh weight (74.62%) and root dry weight (66.66%) under NaF stress.

By analyzing the morphological transformation of heavy metals and their accumulation in plants, the passivation effects on various heavy metals were evaluated. Results showed that FA converted exchangeable iron (Fe), copper (Cu), zinc (Zn) and cadmium (Cd) to a residual state, and CS reduced the reducible Cu and Zn concentrations. The FC transformed Fe, manganese (Mn), lead (Pb) and Cd from exchangeable and reducible states to oxidizable and residual states. At the 6% addition rate, the passivation efficiencies of FC for Fe, Mn, Pb and Cd reached 34.33, 9.98, 14.92 and 17.32%, respectively. Meanwhile, FC inhibited the enrichment of Cu, Zn, Pb, and Cd in ryegrass.

The optimal conditions for maximum biosorption were obtained at pH 5, 0.5 g biosorbent dosage per 10 mL, 6 h of contact time, and initial concentration of 17 and 30 µg/mL for Cu (II) and Ni(II).

Thermodynamic analysis revealed the spontaneous and endothermic nature of the biosorption process. The SEM, EDX, and FTIR analysis were conducted to determine the metal uptake and presence of functional groups responsible for biosorption of metals. FESEM analyses has confirmed the surface morphology; the presence of Cu(II) and Ni(II) peaks after adsorption were confirmed by EDX; and the FTIR study confirmed the presence of hydroxyl, carboxyl, amine, phosphate, and amide functional groups in the biomass. The results demonstrated that SMC exhibited greater biosorption efficiency [93.88% for Cu(II) and 88.5% for Ni(II)] than ABM [91.43% for Cu(II) and 86.63% for Ni(II)], in order Cu(II) > Ni(II), making both viable options for the removal of heavy metals from aqueous medium.

The process effectively treated 500 mL of synthetic wastewater containing 100 ppm zinc ion and the process could be enhanced to achieve the removal efficiency of 90% by adjusting the solution pH to slightly acidic (pH 5) and increasing the mass of duckweed to its saturation point (20 g). Excessive zinc intake by duckweed led to chlorophyll reduction, negatively impacting the duckweed growth rate. Scanning electron microscopy (SEM) analysis revealed that the duckweed fronds' surface became uneven after the treatment, with the irregular small particles attached due to cellular damage. The energy dispersive X-ray (EDX) analysis confirmed the successful uptake and accumulation of zinc in the duckweed cells from the synthetic wastewater.

The study highlights the benefits of native species in enhancing soil quality and resilience. Key soil parameters, including pH, moisture, and organic carbon, were monitored to study their effects on geotextile biodegradation and plant growth. Our findings indicate that jute geotextiles offer a sustainable alternative to synthetic materials, degrading within 1-2 years while promoting vegetation, making them ideal for short to medium-term projects.

To yield a worthwhile remediation performance, phytoremediation technology involves amalgamating multifarious techniques and strategies. The primary objective of this research was to look into the effects of seasonal changes, contamination level, and EDTA chelation on Brown mustard's potential to extract Lead (Pb) from synthetically contaminated soil and its response to antioxidant enzyme activity. Soil samples containing 5 mg kg-1 of EDTA were spiked with 200, 500, and 1000 mg kg-1 of Pb, while the control group (unspiked) without EDTA addition was used. The results indicated that adding EDTA in winter (winter + EDTA) significantly increased (p < 0.05) plant growth by 18.83%. Observing the seasonal variation, the removal efficiency of Pb was achieved in this order: summer + EDTA > winter + EDTA > summer + No EDTA > winter + No EDTA. The results also showed that the removal rate had improved up to 52.53% as the concentration of Pb rose from 67 to 500 mg kg-1 but showed a decline after reaching 1000 mg kg-1, indicating a maximum Pb stress level. Additionally, the EDTA chelation during winter demonstrated a significant effect on the ability of Brown mustard to accumulate higher levels of Pb in both roots and leaves, with 500 mg kg-1 as the optimal level taken by the plant throughout the experiment. Except for CAT, the increased enzyme activities were observed under EDTA chelation while Pb-stress (1000 mg kg-1) reduced the enzyme activities by over 4%. The findings suggest that having 143 U/g CAT, 285 U/g SOD, and 14.9 U/g MDA in the summer season with EDTA amendments were the most suitable recourse for decontamination of Pb-polluted soil compared to a single-factor treatment.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"1-13"},"PeriodicalIF":3.4,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143995371","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}
