However, the health risks associated with metal transfer along the soil-root-cicada pathway require further elucidation. Inductively coupled plasma optical emission spectrometry analysis of soil (n = 36), poplar root (n = 9), and cicada life stage (n = 27) samples revealed distinct heavy metal distribution patterns. Soil concentrations (mg·kg-1) ranged as follows: Cd 0.03-5.67, Pb 2.50-433, Cu 11.25-37.73, Ni 27.00-65.50, Zn 58.33-141.50. Metal partitioning showed Cd (0.16-33.05 mg·kg-1) and Cu accumulating in adult cicadas, while Zn (peak 609 mg·kg-1), Pb (0.30-94.33 mg·kg-1) and Ni were predominantly retained in exuviae. Notably, Zn exhibited particularly strong bioaccumulation from roots. Cd and Pb concentrations in edible cicada stages and Cd in exuviae exceeded safety limits, correlating with substantial root accumulation (Cd: 0.75-19.67, Pb: 4.32-85.33 mg·kg-1). Risk assessment showed negligible non-carcinogenic risks (HQs < 1.0) at typical consumption rates, though adults presented higher Cd-related risks than nymphs. Soil Cd safety thresholds were established at 1.52 mg·kg-1 (adults) and 3.97 mg·kg-1 (nymphs). These findings demonstrate significant trophic transfer amplification of metal risks and provide crucial safety benchmarks for sustainable cicada production.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"1105-1117"},"PeriodicalIF":3.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145700848","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}

In this study, a hydroponic experiment was conducted using Phytolacca americana exposed to lanthanum (La) and yttrium (Y) in combination with varying concentrations of citric acid or malic acid, and plant growth, elemental concentrations and systemic responses were evaluated. Citric acid markedly promoted lanthanum accumulation in aboveground tissues, reversed the inherent plant preference for yttrium and increased the lanthanum to yttrium ratio, consistent with enhanced long distance transport. In contrast, malic acid did not significantly promote lanthanum translocation but instead enhanced root thickening and supported the coordinated uptake of essential nutrients, thereby maintaining ionic homeostasis and biomass. Multivariate analyses confirmed that citric acid induced a lanthanum centered fractionation pattern at the expense of nutrient balance, whereas malic acid sustained nutrient coordination. These findings provide mechanistic insights into the biogeochemical controls governing rare earth element mobility and have direct implications for the design of phytoremediation strategies based on low molecular weight organic acids for soils contaminated by rare earth elements.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"1177-1190"},"PeriodicalIF":3.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145774591","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 demonstrated that continuous grafting significantly reduced both biomass and antioxidant enzyme activities in tomato scions. Specifically, compared to non-grafted controls, the root biomass of secondary and tertiary grafted plants decreased by 40.21% and 40.38%, respectively. Concurrently, a reduction in DNA methylation levels was observed across cuttings and grafted generations. Demethylation emerged as the predominant pattern in seedlings, while hypermethylation was notably present in the progeny of tertiary grafted plants. Although the Cd content in the cuttings themselves was not significantly altered, continuous grafting markedly increased Cd accumulation within various tissues of the subsequent grafted generation plants. Furthermore, it contributed to a reduction in Cd bioavailability in the soil. In summary, continuous grafting suppressed the growth of the grafted cuttings but paradoxically enhanced both growth and Cd uptake capacity in their progeny. This study provides a theoretical foundation for employing grafting techniques to modulate crop physiological responses to Cd-contaminated soil. Subsequent research incorporating transcriptomic analysis is recommended to elucidate the molecular mechanisms underlying these transgenerational effects.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"1235-1245"},"PeriodicalIF":3.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145827588","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}

In this study, Monochoria korsakowii was exposed to 0.1 or 0.3 mM Cd for six days and foliar-sprayed with SA biosynthesis inhibitors (2-aminoindane-2-phosphonic acid and 1-aminobenzotriazole) to elucidate endogenous SA functions under short-term Cd stress. The results showed that Cd stress reduced total chlorophyll content, the net photosynthetic rate, and the performance index on an absorption basis. The upregulation of specific antioxidant enzymes and non-enzymatic antioxidants contributed to limiting malondialdehyde accumulation. Lastly, Cd stress enhanced the activities of benzoic acid 2-hydroxylase (BA2H) and phenylalanine ammonia-lyase (PAL), two key enzymes involved in SA biosynthesis. However, SA inhibitors reversed the Cd-induced upregulation of PAL and BA2H activities and aggravated the Cd-induced decline in photosynthetic performance. Furthermore, compared with the corresponding Cd treatments, SA inhibitors, reduced antioxidant enzyme activities and proline levels, and exacerbated Cd-induced malondialdehyde accumulation. Finally, SA inhibitors significantly increased the levels of phytochelatins and non-protein thiols. These results indicate that SA is a critical endogenous signal for enhancing plant Cd tolerance, which lays a theoretical foundation for developing phytohormone-based phytoremediation strategies.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"2310-2326"},"PeriodicalIF":3.1,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147689913","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}

Optimal biosorption occurred at a dye concentration of 100 mg L-1 using 2% biosorbent at pH 2 within 60 min, resulting in >70% dye removal. Adsorption capacities of biosorbents ranged from 8.7 to 36.6 mg g-1. Kinetic studies demonstrated that dye uptake followed a pseudo-second-order model (R2 > 0.9). Isotherm analysis revealed that adsorption on banana followed the Freundlich model, whereas RB-carrot peel data did not conform to any conventional isotherm model, indicating more complex adsorption behavior in the blended dye system. FTIR, SEM, and BET analyses confirmed pore-filling and surface binding of the dye mediated by weak interactions involving hydroxyl, carboxyl, amine, and aromatic functional groups.

Cr stress severely inhibited plant growth, reducing shoot length, fresh weight, and dry weight by 16%, 20%, and 20%, respectively, while increasing root length by 23%. Photosynthetic pigments, gas exchange attributes, and water use efficiency (WUE) were also significantly impaired under Cr stress. CuONPs surpassed the effects of CuSO4 and increased shoot length, shoot fresh weight, and shoot dry weight by 27%, 27%, and 24%, respectively, in Cr-stressed plants. Additionally, CuONPs enhanced photosynthetic efficiency, reduced oxidative stress markers (malondialdehyde and hydrogen peroxide), and improved antioxidant enzyme activities (SOD, POD, APX, and CAT). Principal component analysis revealed that CuONPs-treated plants under Cr stress were closely aligned with control plants, demonstrating their effectiveness in mitigating Cr-induced damage.

Alkali treatment reduces hydrophilic components, enhancing water stability, while citric acid introduces carboxylic groups that improve dye adsorption. Characterization via FTIR, FESEM-EDX and BET confirmed the presence of polyphenols, porous tube-like structures, and a surface area of 3.79 m2/g. pHzpc of the material is 4.50. The experimentally determined adsorption capacities for CV and MB were 59.19 mg/g and 59.50 mg/g, respectively, at an initial concentration of 1000 mg/L, under optimal conditions (45 min, 0.1 g dose, pH 7). High adsorption capacity despite low surface area highlights the dominant contribution of functional-group-mediated chemical interactions. Adsorption followed pseudo-second order kinetics; CV fit the Temkin isotherm, and MB fit the Langmuir isotherm models. The material was reusable for three cycles with methanol regeneration in CV, and HCl in MB, and common ions caused minimal interference.

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%.
