Evaluating marine environmental pollution using Fuzzy Analytic Hierarchy Process (FAHP): A comprehensive framework for sustainable coastal and oceanic management
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.
The ecological risk and fate of microplastics in the environmental matrices of marine ranching area in coastal water
Researchers surveyed microplastics across five environmental compartments — surface water, middle water, bottom water, sea bottom sediment, and intertidal sediment — in a marine ranching area of Haizhou Bay, China. Sediments carried significantly higher microplastic risk than the water column, and the study found that artificial reefs may drive upwelling that pushes bottom microplastics toward the surface. Aquaculture activities appear to be a key local source, pointing to the need for stricter regulation of plastic gear used in fish farming.
Sensitivity of Natural Environment of Tourist Attractions Based on Fuzzy Comprehensive Evaluation

Multiple approach for assessing lagoon environmental status based on water bodies quality indices and microplastics accumulation
Researchers assessed lagoon environmental status using water quality indices and microplastic accumulation measurements, finding that combining these multiple approaches provides a more comprehensive evaluation of lagoon ecosystem health than single metrics alone.
Development of a framework and toolbox for measuring and evaluating ecosystem interactions of seaweed aquaculture
This Dutch-language study (mostly in Dutch) developed a framework and toolbox for measuring ecosystem integrity in seaweed cultivation areas off the Dutch coast, relevant to scaling up sustainable aquaculture. Healthy coastal ecosystems with minimal microplastic contamination are important for sustainable seaweed production.
A new holistic perspective to assess the ecological risk of microplastics: A case study in Baiyangdian Basin, China
Researchers developed a more comprehensive method for assessing the ecological risks of microplastic pollution by considering not just concentration but also the physical and chemical properties of the particles. Applied to a Chinese wetland basin, the approach revealed that traditional methods significantly underestimate the true ecological risk, with human activity and poor water flow contributing to the highest danger zones.
Spatial heterogeneity of microplastics and ecological risk assessment based on detection of seawater and fish in typical coastal region in Hainan
Spatial heterogeneity in microplastic concentrations across a study area was documented and linked to ecological risk, with hotspots identified near point sources and areas of low water flow. The risk assessment framework developed here can help prioritize sites for remediation or regulatory attention.
Integrated Ecological Risk Assessment of the Agricultural Area under a High Anthropopressure Based on Chemical, Ecotoxicological and Ecological Indicators
Researchers conducted an integrated ecological risk assessment of agricultural land using chemical, ecotoxicological, and ecological indicators, finding that while chemical analysis overestimated risk, the combined approach revealed most of the area had acceptable risk levels despite over a century of anthropogenic pressure.
Impact of microplastic pollution on coastal ecosystems using comprehensive beach quality indices
This study applied three beach quality indices to assess microplastic pollution in Chinese beach sediments, finding that all sampled beaches rated "very high" pollution and "bad" environmental status. The work provides a standardized framework for quantifying microplastic impact on beach environments, which is useful for guiding cleanup priorities and policy decisions.
Microplastic pollution and ecological risk assessment in an estuarine environment: The Dongshan Bay of China
Researchers conducted the first survey of microplastic pollution in Dongshan Bay, a Chinese estuary, and found concentrations averaging 1.66 particles per cubic meter of surface water. The most common plastics were polypropylene, polyethylene, and polystyrene foam, likely originating from local fishing and aquaculture activities. An ecological risk assessment rated the bay at a moderate hazard level, establishing important baseline data for future monitoring.

Microplastic pollution and ecological risk assessment of Yueqing Bay affected by intensive human activities
Scientists surveyed microplastic pollution in Yueqing Bay, China, finding contamination in seawater, sediments, and marine organisms, with mariculture and shipping identified as major sources. The pollution levels ranged from low to medium compared with other coastal areas, but the ecological risk assessment found concerning levels for certain plastic polymers. The study highlights how concentrated human activities along coastlines contribute to microplastic contamination of marine environments and the organisms people harvest for food.
Multidimensional Assessment of Microplastic Pollution in Mangrove Wetlands: Driving Mechanisms, Carbon Contribution, and Ecological Risk
Scientists found tiny plastic particles called microplastics throughout mangrove wetlands in China, with the highest levels in areas used for fishing and fish farming. These plastic particles are building up in the sediment and water, creating pollution hotspots that pose moderate ecological risks to these important coastal ecosystems. This matters because mangroves help protect coastlines and support marine life that humans depend on for food, so plastic pollution in these areas could ultimately affect our food supply and coastal protection.
