    Current Trends in Environmental Impact and Risk Assessment
    (Tailor and Francis, 2026) Alhassan, Alhassan Muhammad; Isibor, Patrick Omoregie; Chimbekujwo, Konjerimam Ishaku; Oyewole, Oluwafemi Adebayo; Adetunji, Charles Oluwaseun
    In the modern world, an essential tool for environmental policy is the Environmental Impact Assessment (EIA). EIAs have been used in almost every country on the earth since they were initially included in the 1969 US National Environmental Protection Act (NEPA). A recent study found that the EIRA was incorporated into the legal frameworks of 183 of the 197 nations that were assessed. These numbers will increase if one accounts for the countries that ratify international accords or other documents mentioning the usage of EIRA even though they do not have legally necessary EIRAs. The use of EIRA has increased across national jurisdictions, financial institutions, and large organizations.

    Current Advances in Aquatic and Marine Toxicology
    (Tailor and Francis, 2026) Isibor, Patrick Omoregie; Oyewole, Oluwafemi Adebayo; Adetunji, Charles Oluwaseun
    Aquatic and marine toxicology is a rapidly evolving field that addresses the complex and multifaceted challenges posed by environmental pollutants and climate change. This comprehensive review highlights key areas of focus and future directions, including advanced technological applications, integrative risk assessment methodologies, emerging contaminants, and the implications of climate change. Automated liquid handling systems (ALHS) and high-content screening (HCS) are revolutionizing toxicological research by enhancing precision, throughput, and data quality. Advanced bioinformatics tools facilitate the management and analysis of large datasets, supporting the identification of toxicological patterns and comprehensive risk assessments. Integrative frameworks, such as Adverse Outcome Pathways (AOPs) and Weight-of-Evidence (WoE) approaches, enhance the robustness of regulatory decisions by linking molecular events to adverse outcomes and combining diverse data sources. Emerging contaminants, including microplastics, nanomaterials, and pharmaceuticals, present new regulatory challenges, necessitating detailed studies on their environmental fate, bioavailability, and toxicological effects. The interplay between climate change and pollution introduces additional complexity, with research focusing on multi-stressor effects and the resilience of aquatic organisms and ecosystems. Public engagement through citizen science and educational programs enhances environmental monitoring and promotes stewardship. Future research directions emphasize integrative approaches, advanced modelling techniques, and innovative monitoring technologies to improve our understanding and management of aquatic and marine toxicology. These efforts are critical for safeguarding aquatic ecosystems and ensuring the sustainability of water resources in an era of unprecedented environmental change.

    Community-Level Metrics
    (ResearchGate, 2026) Isibor, Patrick Omoregie; Oyewole, Oluwafemi Adebayo
    A complete evaluation of ecological stress responses depends on community-level assessment of diversity abundance with functional traits in aquatic systems suffering from pollution. The amount and variety of species present within a community lead to essential information about how disturbance affects ecosystems and provides evidence for habitat damages and toxicity from pollutants. Evaluating functional traits that include eating strategies together with life history features and tolerance capacity gives scientists a fundamental understanding of ecosystems and stress resilience behavior. Such attributes enable researchers to understand the ways communities transform when confronted by pollutants because the communities either select tolerant species or adopt opportunistic species to survive. A biomonitoring framework becomes more effective ecologically and sensitive when it incorporates both structural elements (richness and evenness) alongside functional measurements. Trait based approaches enable scientists to compare different ecosystems through their ability to predict both emerging contaminant and global change reactions. The combined evaluation of key species compositions with ecological functions enables community-based metrics to deliver complete assessment of ecological health, which industry and governmental organizations now integrate into environmental impact assessment and management tactics.

    Agricultural Applications of Novel Mushroom-Based Nanopesticide
    (WILEY Online Library, 2025-03) Isibor, Patrick Omoregie; Oyewole, Oluwafemi Adebayo; Buba, Adamu Binta; Alhassan, Alhassan Muhammad; Adetunji, Charles Oluwaseun
    Nanobiopesticides derived from mushrooms offer a novel approach to tackling agricultural pests and diseases. These nanoparticles utilize bioactive compounds found in mushrooms to provide targeted pest and pathogen control. Their unique properties enhance penetration, allowing precise delivery to pests and pathogens while minimizing non-target effects. This technology reduces environmental impact and toxicity concerns associated with conventional pesticides. Synthesis methods involve green techniques, aligning with sustainable practices. Challenges include variability in effectiveness and regulatory considerations. Nevertheless, the potential benefits are vast, from effective pest management and disease suppression to improved crop yields and ecosystem health. Nanobiopesticides showcase the synergy of nature and technology, aimed at reshaping agricultural practices toward a more sustainable and eco-friendly future. This paper outlines the relevant literary discourse surrounding these concepts while emphasizing the significance of addressing agricultural challenges related to pests and diseases with this novel approach.

    Advancing the One Health Paradigm Through Integrated Biomonitoring
    (Tailor and Francis, 2026) Akinsanya, Bamidele; Isibor, Patrick Omoregie
    People, animals, and the environment are part of the One Health paradigm, which adds how humans and other animals interact with one another and their environment, thereby providing a holistic model for understanding the challenges posed by anthropogenic pressures and ecological changes. Biomonitoring – the systematic observation of biological response to environmental stressors – becomes a vital instrument in operationalizing the One Health concept, especially in the identification of early indicators of ecological damage and exposure to contaminants. This chapter looks at how integrated biomonitoring frameworks can create disciplinary boundaries and improve environmental surveillance and information on holistic risk assessments. By using bioindicators from across trophic levels as well as sentinel species in terrestrial and aquatic systems, biomonitoring offers a strong determination of contaminant mechanisms, ecosystem health, and zoonotic disease threats. The chapter discusses recent methodological progress, such as molecular biomarkers, integration of remote sensing, and community-based participatory monitoring, all of which enhance the predictive capability and spatial extent of biomonitoring networks. Case studies demonstrate how integrated biomonitoring has guided One Health interventions in areas including the following: antimicrobial resistance, pesticide exposure, and climate sensitive vector-borne diseases. The chapter also discusses issues concerning data harmonization, ethical governance and crosssectoral partnerships. In the long term, the advancement of the One Health agenda needs stretching biomonitoring into the policy frameworks, public health approaches, and ecosystem management to build resilience through timely evidence-informed decision-making at the human–animal–environment interface.

    Adaptive Responses and Evolutionary Implications
    (2026) Isibor, Patrick Omoregie; Efuwape, Temitope Oluseun
    For aquatic organisms residing in contaminated habitats, adaptation becomes essential since it represents their key to survival and maintaining their presence. Long-term evolutionary modifications through genetic changes join behavioral changes and biochemical regulations as well as short-term physiological acclimation to form adaptive responses in aquatic organisms. The mechanisms through which organisms defend against pollutant stress involve higher expression levels of detoxification enzymes together with increased antioxidant protection and modified reproductive procedures. Persistent pollution in populations creates selection pressure that results in the development of new tolerant phenotypes alongside different genotypic and phenotypic traits. The physiological changes that help organisms survive environmentally toxic areas potentially reduce their performance levels in non-polluted zones as well as deteriorate their relationships within food chains and potentially lower their capacity for genetic diversity. Ecosystem structure together with resilience and function face significant consequences as a result of evolutionary processes. The accurate prediction of long-term ecosystem responses requires knowledge of adaptive responses together with evolutionary modifications to perform proper environmental risk assessment under changing global conditions.
