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.
Effects of microplastics and nanoplastics on host–parasite interactions in aquatic environments
Researchers reviewed how microplastics and nanoplastics affect the interactions between parasites and their hosts in aquatic environments. Evidence indicates that plastic particles can influence infection rates, parasite transmission, and host immune responses, though the effects vary widely depending on the species and type of plastic involved.

Researchers found that microplastic exposure increases the susceptibility of midwife toad larvae to the chytrid fungus Batrachochytrium dendrobatidis, suggesting that plastic pollution may worsen the impacts of this devastating amphibian disease.
Less impact than suspected: Dietary exposure of three-spined sticklebacks to microplastic fibers does not affect their body condition and immune parameters
Researchers found that dietary exposure to polyester microplastic fibers at environmentally relevant and elevated concentrations had no significant effects on growth, body condition, or immune parameters of three-spined sticklebacks over nine weeks.
Life on both environment in semi-aquatic frogs: Impact of aquatic microplastic (MP) from MP enrichment to growth, immune function and physiological stress
Researchers exposed juvenile black-spotted pond frogs to different concentrations of microplastics in water to study effects after metamorphosis. They found that microplastics accumulated primarily in the digestive tract and caused reduced growth, increased stress markers, and weakened immune function at higher concentrations. The study suggests that microplastic pollution in freshwater habitats could pose significant health risks to amphibians during vulnerable life stages.
Microplastics Facilitate Protozoan Pathogen Contamination in Shellfish
Researchers found that microplastics can facilitate the contamination of shellfish with disease-causing parasites including Cryptosporidium, Giardia, and Toxoplasma. Oysters exposed to both protozoan pathogens and polyester microfibers harbored significantly more parasites than those exposed to pathogens alone, suggesting microplastics may serve as vectors that increase pathogen levels in seafood.
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.
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.

Distribution of microplastics in tadpoles, adults, and habitats of three water frogs of Pelophylax spp.
Researchers examined microplastics in water frogs and their habitats across Turkey, finding that while tadpoles showed almost no microplastic ingestion, 44% of adult frogs had microplastics in their digestive tracts — mostly fibers from synthetic textiles. The findings highlight how microplastic contamination increases with life stage and proximity to human activity, threatening amphibian populations already under environmental stress.
Microplastic Contamination in Three Amphibian Species: Implications for Amphibian Ecosystems
Researchers investigated microplastic contamination in tadpoles of three amphibian species collected from two Thai provinces, finding 26 microplastic particles — both fragments and fibers — across all species following hydrogen peroxide digestion and stereomicroscopic analysis. The banded bullfrog (Kaloula pulchra) carried the most particles (15), all fibers, indicating widespread environmental exposure even at early developmental stages.
Microplastics exacerbate virus-mediated mortality in fish
Researchers discovered that microplastics can significantly worsen virus-related mortality in fish, finding that salmonids co-exposed to a virus and microplastics, particularly microfibers, died at higher rates than fish exposed to the virus alone. Natural non-plastic microparticles did not produce the same effect, indicating a plastic-specific interaction. The study presents evidence that microplastic pollution may amplify the impacts of infectious disease in aquatic populations.
