Plastic Leachates Disproportionately Impair Aquatic Animals: A Multifactor, Multieffect, and Multilevel Meta-analytic Model
This large-scale analysis of 115 studies found that chemicals leaching out of plastics significantly harmed aquatic animals, reducing survival by 28%, impairing development by 30%, and hurting reproduction by 13%. Marine species were more sensitive than freshwater species, and smaller organisms at the base of the food chain were most vulnerable. These findings are important because toxic chemicals leaching from plastic waste can accumulate through the food chain and ultimately reach humans through seafood.
Effects of microplastics on the toxicity of co-existing pollutants to fish: A meta-analysis
Meta-analysis of 1,380 biological endpoints from 55 studies found that microplastics in co-existing pollutant solutions significantly increased toxicity to fish beyond what the pollutants caused alone, particularly elevating immune system damage, metabolic disruption, and oxidative stress. The effect depended on fish life stage and microplastic size, but not on pollutant or polymer type.
Aging process potentially aggravates microplastic toxicity in aquatic organisms: Evidence from a comprehensive synthesis
This meta-analysis found that environmental aging of microplastics significantly worsens their toxicity to aquatic organisms overall, particularly harming algae, zooplankton, and fish. However, the effect varied by organism type — aged microplastics were less toxic to aquatic plants. Aging methods, particle characteristics, and environmental conditions all modulated the severity of toxicity.
Microplastics aggravate the bioaccumulation and toxicity of coexisting contaminants in aquatic organisms: A synergistic health hazard
Researchers conducted a quantitative meta-analysis of 870 endpoints from 40 studies to evaluate whether microplastics increase the bioaccumulation and toxicity of co-occurring contaminants in aquatic organisms. They found that microplastics significantly increased co-contaminant bioaccumulation by 31% and exacerbated toxicity by 18%, with effects manifesting as increased oxidative stress, endocrine disruption, and immunotoxicity. The study confirms that microplastics act as vectors that amplify the hazards of other environmental pollutants.
Micro- and nanoplastics effects in a multiple stressed marine environment
Researchers examined how micro- and nanoplastics interact with other environmental stressors in marine settings, finding that realistic multi-stressor scenarios can amplify or modify plastic toxicity in ways single-exposure studies miss.
An enigma: A meta-analysis reveals the effect of ubiquitous microplastics on different taxa in aquatic systems
This meta-analysis pooled data from multiple studies to assess how microplastics affect aquatic organisms including fish, invertebrates, and zooplankton. Results showed that microplastic exposure can reduce feeding, growth, and reproduction across different species, raising concerns about broader impacts on aquatic food webs.
Functional Trait-Based Evidence of Microplastic Effects on Aquatic Species
Researchers merged data from two global meta-analyses on microplastic effects on benthic invertebrates and fish to compare impacts across functional traits, finding that microplastics impair feeding, reproduction, and growth across both vertebrate and invertebrate aquatic species.
Microplastics in Aquatic Ecosystems: A Review of Ecotoxicological Effects, Exposure Pathways and Trophic Transfer Risks
This review synthesises evidence on the ecotoxicological effects of microplastics in marine, freshwater, and estuarine environments, covering ingestion, bioaccumulation, trophic transfer, and physiological harms across aquatic fauna. It identifies chemical co-contamination and particle size as key modulators of toxicity.
Ecotoxicity effect factors for plastic additives on the aquatic environment: a new approach for life cycle impact assessment
Researchers calculated toxicity effect factors for 75 plastic additives — chemicals mixed into plastics to improve flexibility, durability, and color — gathering 461 data points across 75 aquatic species to assess how much these chemicals harm marine and freshwater life. The resulting factors can be used in life cycle assessments to quantify the environmental damage caused by plastic additives leaching into water, helping guide greener plastic design and policy.
Microplastics induce neurotoxicity in aquatic animals at environmentally realistic concentrations: A meta-analysis
Meta-analysis of 35 studies demonstrated that microplastic exposure at environmentally realistic concentrations (median 0.1 mg/L) significantly decreased brain acetylcholinesterase levels by 16.2% in aquatic animals, confirming neurotoxic effects. The neurotoxicity was linked to particle size and exposure duration but was independent of animal species, polymer type, or concentration.
Meta-analysis of the effects of microplastic on fish: Insights into growth, survival, reproduction, oxidative stress, and gut microbiota diversity
A meta-analysis of 3,757 biological endpoints from 85 studies found that microplastic exposure significantly inhibits fish growth, survival, and reproduction while increasing oxidative damage, but does not significantly alter gut microbiota diversity. The severity of toxic effects depends on microplastic type, size, concentration, exposure pathway, and the fish's life stage.
Toxicity Mechanism, Exposure Pathways, and Environmental Risk Assessment of Microplastic Pollution
This book chapter reviews the toxicity mechanisms and exposure pathways of microplastics in aquatic environments, examining how MPs cause harm through physical ingestion, chemical leaching, and facilitation of co-contaminant transport, and discussing frameworks for environmental risk assessment.
An effect factor approach for quantifying the impact of plastic additives on aquatic biota in life cycle assessment
Researchers developed a preliminary effect factor approach to quantify the environmental impact of plastic additives on aquatic organisms within life cycle assessment frameworks, addressing a critical gap in how marine plastic chemical impacts are characterized.
Cross-ecosystem impacts of plastic pollution: a systematic analysis of environmental threats
A systematic analysis of recent literature on plastic pollution across ecosystems found that microplastics impair organisms through physical ingestion, chemical toxicity, and facilitated transfer of co-contaminants, with cross-ecosystem effects linking terrestrial, freshwater, and marine environments.
Effects of microplastics on the functional traits of aquatic benthic organisms: A global-scale meta-analysis
Microplastics had a moderate overall negative effect on functional traits of aquatic benthic organisms, particularly impairing energy assimilation and population-level traits like reproduction, while behavior and feeding traits appeared unaffected.
Meta-analysis unravels the complex combined toxicity of microplastics and antibiotics in aquatic ecosystems
A meta-analysis of 730 datasets found that microplastics amplify antibiotic accumulation in aquatic organisms and worsen effects on growth, development, and immune function, but paradoxically appear to mitigate reproductive toxicity from antibiotics. The impact depends on biological response pathway, microplastic concentration, antibiotic properties, and exposure time, with an inverse relationship between antibiotic toxicity and both microplastic concentration and exposure duration.
The legacy effect of microplastics on aquatic animals in the depuration phase: Kinetic characteristics and recovery potential
A meta-analysis of microplastic depuration studies across 68 kinetic curves from aquatic animals found that many species retain a fraction of ingested MPs even after prolonged exposure-free periods, with retention rates and recovery timelines varying by species and MP type. The findings highlight the legacy effects of microplastic exposure that persist after contamination ends.
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.
Microplastics could be marginally more hazardous than natural suspended solids – A meta-analysis
Species sensitivity distributions constructed from harmonized toxicity data suggest microplastics may be marginally more hazardous to aquatic organisms than natural suspended sediments, though high uncertainty prevents definitive conclusions. The lack of comparable experimental studies and dose-dependent data was a major limitation.
Adverse outcome pathway networks of microplastic ecotoxicity to aquatic organisms: A critical review
Researchers used automated text-mining combined with multi-level ecotoxicological review to construct adverse outcome pathway networks for microplastic toxicity in aquatic organisms. They mapped how microplastics cause harm from initial tissue contact through molecular disturbances to higher-level biological effects in gills, gut, liver, gonads, and brain. The study found strong evidence for early-stage toxic mechanisms but identified critical knowledge gaps in understanding downstream biological consequences.
