ClearEffects of micro(nano)plastics on amphibian cell lines
This study assessed the effects of micro- and nanoplastics on amphibian cell lines as an alternative model system for evaluating plastic toxicity, responding to growing concerns about particle impacts on amphibians and the value of cell-based testing. Plastic particles caused measurable cellular damage in amphibian cells, supporting their use as a screening tool.
Ecotoxicological perspectives of microplastic pollution in amphibians
This review summarizes research on how microplastics affect amphibians, which are considered important indicator species for freshwater pollution. Researchers found evidence that microplastics can impair amphibian growth, immune function, and gene expression, with effects varying by species and particle characteristics. The findings raise concerns about the vulnerability of amphibian populations already threatened by habitat loss and other environmental stressors.
Microplastics as an emerging threat to amphibians: Current status and future perspectives
This review summarizes existing research on microplastic contamination in amphibians like frogs and salamanders, finding that over 80% of studied species had accumulated microplastics. The particles persisted in organs, showed toxic and gene-damaging effects, and could transfer through the food chain. Since amphibians are indicators of environmental health, widespread microplastic accumulation in these animals signals broader ecosystem contamination that can ultimately affect human food and water sources.
How much are microplastics harmful to the health of amphibians? A study with pristine polyethylene microplastics and Physalaemus cuvieri
Researchers exposed frog tadpoles (Physalaemus cuvieri) to polyethylene microplastics and found significant harmful effects including DNA damage, cell toxicity, and abnormal physical development. The microplastics accumulated in multiple tissues including the gills, gut, liver, muscle, and blood. The study provides some of the first evidence that microplastics can affect amphibian health, adding to concerns about their impact on freshwater wildlife.
Microplastic pollution and amphibian health: Complex physiological effects of different microplastic types on juvenile Glandirana rugosa
Researchers studied how polypropylene and polyethylene microplastics affect juvenile frogs and found significantly higher mortality rates in microplastic-exposed groups. The frogs showed elevated stress hormones, signs of oxidative damage, and elongated intestines, suggesting their bodies were trying to adapt to the particles. The study highlights that microplastics pose both physical and chemical risks to amphibians, which may contribute to population declines.
Variation in microplastic characteristics among amphibian larvae: a comparative study across different species and the influence of human activity
Scientists examined microplastics inside amphibian larvae from 10 species and found plastic particles in all of them, with blue fibers being the most common type. Larger larvae tended to contain longer plastic fragments, and there was a relationship between human activity levels near habitats and the characteristics of the plastics found. This study shows that microplastic contamination has penetrated freshwater food webs, affecting animals during their most vulnerable developmental stages.
Micro(nano)plastics as an emerging risk factor to the health of amphibian: A scientometric and systematic review
Only 12 studies have examined microplastic effects on amphibians, concentrated in Brazil and China and limited mostly to the Anura order; lab-tested concentrations were far from environmentally relevant levels, leaving significant knowledge gaps about mechanisms of toxicity in this vertebrate group.
Is cell culture a suitable tool for the evaluation of micro- and nanoplastics ecotoxicity?
This review assessed cell culture as a tool for evaluating micro- and nanoplastic ecotoxicity in aquatic organisms, identifying its advantages for high-throughput screening while noting limitations related to relevance to whole-organism and ecosystem-level effects.

This review examines cellular effects of microplastic and nanoplastic exposure in aquatic organisms, synthesizing laboratory evidence that plastics alone or combined with other toxicants cause membrane lysis, mitochondrial damage, reactive oxygen species generation, genotoxicity, and apoptosis.
Toxicity of silver, lead an nanoplastics to early life stages of amphibians
This study tested the toxicity of silver, lead, and nanoplastics on early life stages of amphibians, which are already declining globally due to human disturbances. Results indicate these contaminants pose additional risks to a group of vertebrates that is highly sensitive to environmental changes due to their permeable skin.
Microplastics from miscellaneous plastic wastes: Physico-chemical characterization and impact on fish and amphibian development
Researchers created microplastics from real-world miscellaneous plastic waste and tested their effects on zebrafish and frog embryo development. The waste-derived microplastics, which more closely resembled environmental particles than commercial microspheres, caused species-specific effects including delayed hatching in zebrafish and intestinal accumulation and tissue stress in frog embryos.

Genotoxicity, mutagenicity and immunotoxicity assessment of microplastics and nanoparticle mixture in bullfrog tadpoles
Researchers exposed bullfrog tadpoles to polyethylene microplastics and titanium dioxide nanoparticles, both individually and in combination, for 15 days to assess genetic damage and immune effects. While the pollutants did not cause direct DNA damage at the tested concentrations, the microplastics alone and in combination with nanoparticles triggered changes in immune cell composition. The study suggests that even at relatively low concentrations, microplastics can alter immune function in amphibians, which are among the most threatened vertebrate groups worldwide.
