Soil toxicity is a major environmental issue that leads to numerous harmful effects on plants and human beings. Every year huge amount of Pb dumped into the environment either from natural sources or anthropogenically. Being heavy metal it highly toxic non-biodegradable but remains in for long time. It considered neurotoxic exerts living In present review article, investigators have emphasized side plants. Further, authors focused various environment. Investigators responses including molecular, biochemical, morphological levels Pb. Further emphasis was given effect elevated microbial population rhizospheres. remediation strategies removal soil water sources.

Arsenic (As) is a naturally occurring chemical element widely distributed in the Earth's crust. Human activities have significantly altered As presence environment, posing significant threats to biota as well human health. The environmental fates and adverse outcomes of various species been extensively studied past few decades. It imperative summarize these advances whole provide more profound insights into cycle for sustainable development. Embracing One Health concept, we systematically reviewed previous studies this work explored following three fundamental questions, i.e., what trends associated changes are contamination, how living organisms interact cope with most importantly do achieve future As. By focusing on one critical question each section, review aims full picture complexity To tackle research challenges gaps pollution mitigation, further proposed framework potential coping strategies, guiding coordinated agenda dealing legacy environment ensuring future.

Electrocatalytic nitric oxide reduction (eNORR) to ammonia (NH3) provides an environmental route alleviate NO pollution and yield great-value chemicals. The evolution of eNORR has been primarily hindered, however, by the poor reaction kinetics low solubility in aqueous electrolytes. Herein, we have rationally designed a cobalt-based composite with heterostructure as highly efficient catalyst. In addition, integrating boron modulate electronic structure, catalyst CoB/Co@C delivered significant NH3 315.4 μmol h–1 cm–2 for outstanding power density 3.68 mW Zn-NO battery. excellent electrochemical performance is attributed enrichment cobalt dual-site adsorption fast charge-transfer kinetics. It demonstrated that pivotal enhancement NO, suppression hydrogen evolution, Co oxidation boost performance.

Antimony (Sb) in natural water has long-term effects on both the ecological environment and human health. Iron mineral phase transformation (IMPT) is a prominent process for removing Sb(V) from water. However, importance of IMPT eliminating Sb remains uncertain. This study examined various Sb-Fe binding mechanisms found different pathways water, shedding light underlying mechanisms. The revealed that presence goethite (Goe), hematite (Hem), magnetite (Mag) significantly affected concentration Elevated pH levels facilitated higher Fe content iron solids but impeded Sb(V). To further our understanding, polluted samples were collected locations surrounding smelter sites. Results confirmed converting ferrihydrite (Fhy) to Goe reduced (<5 μg/L) emergence secondary phases resulted greater electrostatic attraction stabilized surface complexes, which was most likely cause decline comprehensive findings offer new insights into factors governing as well behavior control.

With the development of industrial activities and agricultural mining industries, farmland soils are facing serious problems related to heavy metal contamination, especially cadmium (Cd) arsenic (As) contamination. In this study, two by-products, phosphogypsum (PG) red mud (RM), were modified by lanthanum (La) impregnation form a new composite (L-PR) investigate adsorption performance Cd(II)/As(V) in both single binary systems. The mechanisms on L-PR analyzed using SEM, XRD, FTIR, XPS. passivation effect Cd-As contaminated soil was confirmed through cultivation experiment. experiments revealed that showed superior capabilities for Cd(II) As(V) compared PG RM. Additionally, found be less affected changes pH. kinetic studies indicated followed second-order model most accurately. Isothermal more accordance with Freundlich model, while Langmuir model. involved electrostatic attraction, ion exchange, complexation, precipitation. is dominated complexation precipitation, exchange complexation. Soil significantly reduced available Cd As concentrations 86.01% 27.80%, respectively, it could induce transformation non-stable stable residual. summary, exhibits facile preparation, excellent performance, capable simultaneously removing from aqueous solutions immobilizing these contaminants soil. These remarkable attributes made highly promising alternative simultaneous treatment various toxic contaminants.
