Abstract The development of industry has led to an increase in environmental pollution. primary objective this study was evaluate the selective absorption Pb and Zn by kaolinite soil binary single-component systems. Furthermore, kinetics isothermal adsorption at low high concentrations were investigated. To end, under controlled experimental conditions, initially combined with lead zinc artificially contaminated solutions containing 5 20 Cmol kg-1 separate systems a ratio 1:20 triplicate. Subsequently, samples prepared according EPA method. results showed that decreasing pH 2 both systems, pollutants, concentrations, percentage decreased significantly. However, alkaline acidic conditions for pore fluids exceeded Zn. Pb2+ remained constant systems; however, Zn2+ significantly reduced component-system compared system. Additionally, findings indicated Langmuir isotherm exhibited highest consistency two heavy metals studied concentrations. Moreover, pollutants better described first Pseudo equation, rate values equation second Zn2+> Pb2+.

AbstractSoil pollution from potentially toxic elements (PTEs) is a serious environmental issue worldwide that affects agricultural safety and human health. Arbuscular mycorrhizal fungi (AMF), as ecosystem engineers, can alleviate PTE toxicity in crop plants. However, the comprehensive effects of AMF on performance PTE-contaminated soils have not yet been recognized globally. Here, meta-analysis 153 studies with 3213 individual observations was conducted to evaluate growth accumulation five staple crops (wheat, rice, maize, soybean, sorghum) contaminated soils. Our results demonstrated had strong positive shoot root biomass. This because effectively oxidative damage induced by PTEs stimulating photosynthesis, promoting nutrition, activating non-enzymatic enzymatic defense systems also decreased 23.6% increased 0.8%, demonstrating inhibited transfer uptake shoot. Meanwhile, AMF-mediated were weaker pH > 7.5. Overall, this global survey has essential implications ability enhance provides insights into guidelines for safe production worldwide.Keywords: fungipotentially elementscrop growthbioaccumulationphysiological activitiesmeta-analysisHANDLING EDITORS: Jörg Rinklebe Lena Q.

Lignin is a phenolic heteropolymer found in most terrestrial plants that contributes an essential role plant growth, abiotic stress tolerance, and biotic resistance. Recent research grass lignin biosynthesis has differences compared to dicots such as Arabidopsis thaliana . For example, the prolific incorporation of hydroxycinnamic acids into secondary cell walls improve structural integrity vascular elements via covalent crosslinking. Conversely, fundamental monolignol chemistry conserves mechanisms translocation polymerization across phylum. Emerging evidence suggests compositions contribute periods often alter cereal hinder pathogenesis. This same recalcitrance also inhibits industrial valorization biomass, making alterations reductions field research. review presents update biosynthesis, translocation, polymerization, highlights how lignified development responses, briefly addresses genetic engineering strategies may benefit applications.

A comprehensive understanding of cadmium (Cd) migration in soils near contaminated hotspots is crucial for optimizing remediation efforts and ensuring crop health. This study investigates agricultural from four sites mining sewage-irrigation areas, assessing the impact inorganic organic fertilizer application on soil Cd remobilization. Results revealed that fertilization, particularly with mineral phosphorus, disrupts stability, substantially increases short-term mobility vulnerable regions. Random Forest analysis identified elevated dissolved matter pH changes as key drivers Monte Carlo simulation, integrating Michaelis-Menten reaction kinetics model, further accessed potential risk The model predicted probabilities grain exceeding thresholds ranged 021.6 % rice, 13.8 %100 wheat, 084.2 maize absence use. Fertilization significantly increased these exceedance by 6.1 %87.4 %, highest risks observed irrigation-contaminated soils, under phosphorus fertilization. Nevertheless, it recommended while fertilization can elevate remobilization hotspots, strategies might not always be necessary. highlights hybrid data-driven approaches, combining machine learning, mechanistic stochastic prediction to simplify complex environmental process, allowing integrated evaluations.
