Evaluating marine environmental pollution using Fuzzy Analytic Hierarchy Process (FAHP): A comprehensive framework for sustainable coastal and oceanic management
Summary
Researchers applied a fuzzy decision-making framework to rank the relative severity of five major marine pollution sources: chemical contaminants, microplastics, oil spills, eutrophication, and noise pollution. The analysis found that chemical contaminants posed the highest risk, with microplastics ranking second. The study provides a structured tool for policymakers to prioritize environmental protection efforts in coastal and ocean management.
Marine pollution poses a significant threat to ecosystems, biodiversity, and human health, necessitating a structured evaluation framework. This study applies the Fuzzy Analytic Hierarchy Process (FAHP) to prioritize five major marine pollution sources: chemical contaminants, microplastics, oil spills, eutrophication, and noise pollution. The FAHP results indicate that chemical contaminants (0.312) pose the highest risk, followed by microplastics (0.256), oil spills (0.182), eutrophication (0.147), and noise pollution (0.103). Sensitivity analysis confirms ranking stability, with slight variations when specific impact dimensions are prioritized. The findings emphasize the urgent need for regulatory enforcement on industrial discharge, microplastic bans, and oil spill prevention strategies. While eutrophication and noise pollution rank lower, their regional and long-term impacts warrant targeted mitigation efforts. Despite methodological strengths, limitations include expert judgment subjectivity and regional variability in pollution severity. Future research should focus on real-time pollution monitoring and interdependency assessments. This study provides a structured, quantifiable, and regionally adaptable basis for policymakers and environmental managers to prioritize pollution sources. While the types of marine pollutants addressed are broadly recognized, this work offers a reproducible decision-support model tailored to regional environmental contexts and resource constraints, supporting more effective, targeted mitigation strategies.

Assessment of Sustainable Wastewater Treatment Technologies Using Interval-valued Intuitionistic Fuzzy Distance Measure-based Mairca Method
Researchers developed a decision-making framework for evaluating sustainable wastewater treatment technologies using fuzzy set theory and multi-criteria analysis. The method accounts for uncertainty in expert assessments while comparing technologies across economic, environmental, and social criteria. The study provides a systematic approach for selecting wastewater treatment solutions that can address emerging contaminants including microplastics.
Ranking of potential hazards from microplastics polymers in the marine environment
Researchers developed a model to rank which types of microplastic polymers pose the greatest health risk from marine exposure pathways, based on their chemical toxicity when broken down and their particle size. Polyurethane, PVC, and polyacrylonitrile ranked as the most hazardous, while the toxicity of the broken-down chemical components was the single biggest factor in determining risk. This ranking system could help policymakers prioritize which plastic types to regulate first to protect human health.
Which Micropollutants in Water Environments Deserve More Attention Globally?
This review analyzed over 80 studies to determine which chemical micropollutants in water deserve the most attention for cleanup efforts worldwide. Using risk-based methods, researchers identified hundreds of compounds from pharmaceuticals, pesticides, and industrial chemicals that pose risks to aquatic life and human health. While not focused on microplastics directly, the findings are relevant because microplastics can absorb and concentrate many of these same chemicals, potentially increasing human exposure through contaminated water.
