Published: March 4, 2025

This study investigated the impacts of exogenous amino acid supplementation on uptake, translocation, and accumulation yttrium (Y) in tomato plants (Solanum lycopersicum). To understand how acids enhance nutrient uptake plant growth by using Hoagland solution. The results indicated that combination Y with glutamic (Y + Glu) significantly increased concentration leaves to 28.5 ± 1.42 µg g-1, while histidine His) resulted a markedly lower 2.7 0.06 g-1. Notably, proved be particularly effective enhancing xylem sap. control exhibited higher sap flow rate 0.27 0.008 g h-1, which was greater than those treated (p < 0.05). Histidine levels were elevated His treatment, reaching 194.78 13.79 μmol L-1, tryptophan aspartic showed their highest concentrations respective treatments at 109.92 14.43 L-1 212.95 13.65 L-1. These findings demonstrated substantially enhanced phytoextraction plants, through application acid. Further exploration into molecular mechanisms governing complexation transport within phytoremediation is needed.

BIOREMEDIATION: A SUPERIOR ALTERNATIVE FOR REMEDIATING TANNERY EFFLUENT-CONTAMINATED SOIL

FUDMA Journal of Sciences, Journal Year: 2025, Volume and Issue: 9(2), P. 193 - 208

Published: Feb. 28, 2025

Tannery effluent poses significant risks to soil health, primarily through contamination with heavy metals like chromium, sulphides, and persistent organic pollutants (POPs). These toxic substances inhibit microbial activity, reducing nutrient cycling matter decomposition essential for fertility. Beneficial microorganisms, including nitrogen-fixing bacteria, are particularly affected, leading altered communities dominated by less advantageous, metal-tolerant species. Accumulation of POPs disrupts enzymatic activities, interferes plant root growth, complicates remediation efforts due pollutant migration groundwater potential entry into the food chain. Prolonged exposure such contaminants diminishes fertility, reduces resilience, ecosystem services, posing threats agricultural productivity environmental health. This review was aimed outline what made bioremediation a superior treatment technology among other methods used in remediating tannery contaminated soil. Efforts mitigate impacts involve combination physical, chemical, biological technologies. Physical washing, flushing, thermal desorption focus on removing or isolating contaminants, while chemical approaches as oxidation, reduction, stabilization transform harmful forms immobilize them. Biological leverages microorganisms plants detoxify sustainably. Bioremediation strategies aid bioaugmentation biostimulation do enhance activity address inorganic effectively more than physical methods. Another excellent called phytoremediation can also effectively, Achieving better technique should be coupled stringent industrial regulations, sustainable tanning methods, stakeholder awareness

An Experimental Assessment of Miscanthus x giganteus for Landfill Leachate Treatment: A Case Study of the Grebača Landfill in Obrenovac

Processes, Journal Year: 2025, Volume and Issue: 13(3), P. 768 - 768

Published: March 7, 2025

Water pollution caused by landfill leachate, which contains high concentrations of heavy metals and organic contaminants, poses a serious environmental threat. Among the potential remediation strategies, phytoremediation using Miscanthus x giganteus (giant miscanthus) has gained attention due to its strong resistance harsh conditions capacity accumulate metals. This study evaluates effectiveness in treating with focus on removing key pollutants such as zinc (Zn), nickel (Ni), copper (Cu) simulating wetland conditions. A pilot-scale experiment conducted at Grebača site assessed plant’s ability enhance metal bioavailability, stabilize limit their mobility within leachate system. The results demonstrated that effectively mobilized Zn Ni through rhizospheric activity, whereas Cu remained largely immobile, indicating for phytostabilization. Sequential extraction analysis further confirmed plant significantly reduced mobile fractions soil, highlighting dual role both These findings suggest offers sustainable cost-effective approach treatment, serving viable alternative conventional methods. By integrating this nature-based solution into industrial municipal waste management, it promotes sustainability while enhancing efficiency.

Evaluating Potentially Toxic Elements Under Prolonged Application of Pig Manure in Brazilian Soils

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: March 26, 2025

Pig manure (PM) is crucial for animal protein production, especially in Brazil, where pork widely consumed. However, managing waste remains a challenge. While PM serves as soil amendment, it may also introduce potentially toxic elements (PTEs), such heavy metals, into agricultural soils. Few studies address the impact of long-term application on availability these metals at various depths. This study analysed copper (Cu), zinc (Zn), iron (Fe), manganese (Mn), cadmium (Cd), and lead (Pb) soils with prolonged use Florestal (FL), Pará de Minas (PDM), São José da Varginha (SJV), Brazil. Samples were collected from six depths using Mehlich-1 method, element concentrations determined via atomic absorption spectrophotometry. Data ANOVA Duncan’s test (5% probability). The results showed that had higher levels Cu Zn, Cd elevated only PDM. Fe Mn no significant differences, whilst Pb was FL PDM without PM. increased Zn but did not significantly affect other elements. In conclusion, elevates soils, posing potential risks toxicity. Public policies are needed to regulate usage, reduce pollution, promote sustainable management environmental health.

Sustainability, Journal Year: 2025, Volume and Issue: 17(8), P. 3745 - 3745

Published: April 21, 2025

Soil contamination with heavy metals (HMs) poses a significant environmental threat. Phytoremediation, sustainable and eco-friendly emerging bioremediation approach, utilizes plants to remove, immobilize, or stabilize soil contaminants. This study examines the interactive effects of sulfur (S), ethylenediaminetetraacetic acid (EDTA), olive mill wastewater (OMW) on HM uptake growth maize (Zea mays L.) mustard (Brassica juncea). Mustard exhibited superior dry matter (DM) yield (2.4 g/pot 5% OMW), nutrient uptake, tolerance metal toxicity. The translocation factor (TF) bioaccumulation (BF) for vary significantly different treatments. For maize, S 2T/ha treatment achieved highest TF BF cadmium (Cd), while OMW led maximum chromium (Cr) manganese (Mn) uptake. In mustard, resulted in greatest bioconcentration (BCF) lead (Pb), zinc (Zn), whereas application yielded Cd. overall enhanced most significantly. Lower rate (1 ton/hectare) increased availability Cd Pb, boosting plant instance, 1 ton/hectare elevated 24.102 mg·kg−1 58.705 mustard. EDTA treatments further improved bioavailability, increasing levels (10.09 mg·kg−1) (7.78 mg·kg−1). Mustard’s efficiency identify it as promising candidate phytoremediation HM-contaminated soils arid regions. Innovative sulfur, EDTA, enhance decontamination growth.
