ClearMicroplasticsin Aquatic Ecosystems: A MultitieredFramework for Ecological Risk Assessment and Mitigation
This review proposed a multitiered ecological risk assessment (ERA) framework for microplastics in aquatic ecosystems, integrating statistical, mechanistic, and machine learning models. The framework accounts for polymer type, particle size, surface chemistry, and environmental conditions to improve predictive accuracy for long-term ecosystem impacts.

Researchers developed a framework for assessing the ecological risk of microplastic particles, incorporating particle characteristics, environmental concentrations, and species sensitivity data. The assessment identified conditions under which current environmental microplastic levels pose significant risk to aquatic organisms.

Researchers proposed a multilevel risk assessment framework for nanoplastics in aquatic ecosystems that synthesizes complex ecotoxicological datasets into actionable risk indicators, designed to help policymakers set safety thresholds and make decisions about restrictions on petrochemical-derived materials.
Assessment of potential ecological risk for microplastic particles
Researchers applied an ecological risk assessment framework to evaluate the hazard posed by microplastic particles across multiple environmental compartments, using species sensitivity distributions and environmental concentration data. The assessment highlighted specific particle types and size ranges that present the greatest ecological risk.
Assessment of potential ecological risk for microplastics in freshwater ecosystems
Researchers assessed the ecological risk of microplastics across freshwater ecosystems worldwide, including rivers and lakes in China, Vietnam, Europe, and South America. While one risk method showed negligible danger, more comprehensive assessment approaches revealed extreme ecological threats at every location studied, suggesting that microplastic pollution in freshwater may be more serious than previously thought.
[Overview of the Application of Machine Learning for Identification and Environmental Risk Assessment of Microplastics].
This review examines the application of machine learning (ML) methods for identifying microplastics and assessing their environmental risks, covering techniques for improving the accuracy and reliability of microplastic detection across different environmental media. Researchers highlight how ML can systematically analyse pollution characteristics and support ecological risk evaluation of microplastic contamination.
Microplastics: addressing ecological risk through lessons learned
Researchers reviewed the current state of microplastic ecological risk assessment and proposed applying lessons learned from more established fields of environmental research. The study suggests that despite widespread concern about microplastic pollution, scientific understanding of actual ecological risk remains limited, and future research should follow more rigorous risk assessment frameworks.
Review of Recent Advances in Microplastic Ecological Risk Assessment: From Problem Formulation to Risk Characterization
This review of existing research shows that tiny plastic particles called microplastics are contaminating our environment and food chain, carrying harmful chemicals and pollutants that can end up in our bodies. Scientists still don't fully understand how dangerous these microplastics are to human health or how they move through the food we eat, from fish to drinking water. The researchers say we need better methods to study these risks so we can protect people and create policies to reduce plastic pollution.
Risk-based integrated framework for evaluating effects of microplastics to aquatic ecosystems and human health
Researchers developed an integrated risk assessment framework to evaluate how microplastics in water and seafood affect both aquatic ecosystems and human health. They studied microplastic levels in surface water and wild oysters from estuaries in Taiwan and assessed ecological risk, oyster mortality, human intake exposure, and potential liver damage. The study provides a more comprehensive approach to understanding the full chain of risks from microplastic pollution, from waterways to the dinner table.
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.
Global distribution characteristics and ecological risk assessment of microplastics in aquatic organisms based on meta-analysis
This meta-analysis assessed the global distribution of microplastics in aquatic organisms across multiple trophic levels, finding that biological characteristics like body size and feeding strategy significantly influence microplastic ingestion rates. The study provides a framework for ecological risk assessment and proposes strategies to reduce microplastic input into water bodies.
Modeling the spatiotemporal distribution, bioaccumulation, and ecological risk assessment of microplastics in aquatic ecosystems: A review
Researchers modeled the spatiotemporal distribution and ecological risk of microplastics across a coastal marine environment, incorporating hydrodynamic data and bioaccumulation factors for multiple species. The model predicted highest microplastic concentrations near urban outflows with risk extending through the food web.
Toward an ecotoxicological risk assessment of microplastics: Comparison of available hazard and exposure data in freshwaters
Researchers compiled available exposure and toxicity data to perform the first probabilistic risk assessment of microplastics specifically in freshwater environments. The study found that while current concentrations in most freshwaters may not yet pose widespread ecological risk, localized hotspots could exceed harmful thresholds, highlighting the need for more standardized freshwater monitoring.
Analyzing species sensitivity distribution of evidently edible microplastics for freshwater biota
Researchers developed a new framework for assessing the ecological risks of microplastics to freshwater organisms by focusing on species that are known to actually ingest them. The study found that current risk assessment methods may underestimate the danger to freshwater ecosystems and that species known to eat microplastics showed different sensitivity patterns than the broader population of test organisms.

A probabilistic risk framework for microplastics integrating uncertainty across toxicological and environmental variability: Development and application to marine and freshwater ecosystems
Researchers developed a new probabilistic risk assessment framework for microplastics that accounts for uncertainty in how laboratory toxicity data translates to real environmental conditions.
