ClearMeta-analysis of the hazards of microplastics in freshwaters using species sensitivity distributions
This meta-analysis built species sensitivity distributions for microplastics in freshwater and found that predicted no-effect concentrations for pristine microplastics were lower than for weathered ones, suggesting lab studies with new plastics may overestimate real-world hazards. The research highlights that most ecotoxicological studies use pristine microplastics at concentrations far exceeding environmental levels, complicating ecological risk assessment.
Systematic assessment of the mechanisms and risks of micro- and nanoplastic particle exposure in marine invertebrates
Researchers systematically evaluated microplastic and nanoplastic toxicity across diverse marine invertebrate species using data from the ToMEx database. The study constructed species sensitivity distributions and found that nanoplastics generally posed greater hazards than microplastics, with sea urchins and filter-feeding organisms among the most sensitive species, providing ecologically relevant thresholds for risk assessment.
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.

Nanoplastics toxicity in aquatic organisms: a review of effects on selected marine and freshwater species
This review synthesizes findings from 128 studies on the effects of nanoplastics on five representative freshwater and marine species, from microalgae to fish. Researchers found that even at low concentrations, nanoplastic exposure can cause oxidative stress, membrane damage, developmental disorders, and reproductive impairment across species. The study highlights significant knowledge gaps around chronic, environmentally realistic exposure levels and calls for standardized testing methods.
Non-traditional species sensitivity distribution approaches to analyze hazardous concentrations of microplastics in marine water
Researchers analyzed species sensitivity distribution curves for microplastic toxicity in marine water using non-traditional approaches, determining hazardous concentration thresholds across multiple toxicity endpoints to support environmental risk assessment.
Risk-based management framework for microplastics in aquatic ecosystems
This meta-analysis pooled data from 21 toxicity studies to create a risk management framework for microplastics in water. The researchers identified specific concentration thresholds where microplastics begin to harm aquatic life — either by diluting their food supply or by particles entering their tissues. This framework could help regulators set pollution limits to protect ecosystems and, ultimately, human food sources.
Nanoplastics toxicity in aquatic organisms: a review of effects on selected marine and freshwater species
This review analyzed 128 studies on the effects of nanoplastics on five representative freshwater and marine species, including microalgae, bivalves, crustaceans, and fish. Researchers found that even low concentrations of nanoplastics can cause oxidative stress, membrane damage, developmental disorders, and immune and nervous system dysfunction. The study highlights that particle size, concentration, aging status, and the presence of co-contaminants all influence toxicity, and calls for more research at environmentally realistic exposure levels.
