Опубликована: Июнь 20, 2024

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.

Leveraging the One Health concept for arsenic sustainability

Eco-Environment & Health, Год журнала: 2024, Номер 3(3), С. 392 - 405

Опубликована: Март 7, 2024

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.

Heavy metal contamination has gradually become a very much important significant global issue due to its continual existence in the environment and bioaccumulation ecosystems, posing deleterious risks human health. This review aims investigate sources, pathways, toxicological impacts of heavy metals such as cadmium, lead, mercury, arsenic, elucidating their health consequences plausible mitigation strategies. Furthermore, explores dual origins contamination; natural geological processes anthropogenic activities industrial emissions, mining, agricultural practices. These sip into soil, water, food chains, leading bioaccumulation, bio-magnification causing risks, including cardiovascular diseases, neurological disorders, reproductive toxicity. Additionally, addition indigenous case studies from Nigeria, lead poisoning Zamfara State Great Kwa River Cross Rivers underscores disproportionate impact pollution developing nations. reveal socio-economic environmental dimensions issue, providing contextual understanding region-specific vulnerabilities outcomes. To address these problems, evaluates already existing strategies, chelation therapy phytoremediation, while proposing sustainable, cost-effective solutions for reducing exposure mitigating impacts. It emphasizes importance integrative approaches involving policy, community engagement, technological innovations fight effectively. In conclusion, this seminar contributes toxicity, giving showcasing insights sources implications contamination. By integrating theoretical perspectives with practical solutions, provides robust framework informing policy makers advancing sustainable management practices.

Boron-Modulated Electronic-Configuration Tuning of Cobalt for Enhanced Nitric Oxide Fixation to Ammonia

Nano Letters, Год журнала: 2023, Номер 23(15), С. 7120 - 7128

Опубликована: Июль 25, 2023

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.

Unveiling the crucial role of iron mineral phase transformation in antimony(V) elimination from natural water

Eco-Environment & Health, Год журнала: 2023, Номер 2(3), С. 176 - 183

Опубликована: Июль 25, 2023

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.
