ClearSame genus, same burden: Microplastic pollution in banded newts
Researchers examined microplastic ingestion in three species of banded newts from freshwater habitats across Turkey and found plastic particles in 29-43% of individuals. PET fibers were the most common type detected, with no significant differences between species despite their different habitats. The consistent contamination levels across all three species suggest that microplastic pollution is widespread in freshwater environments and that these amphibians may serve as useful indicators of water quality.
Microplastic prevalence in anatolian water frogs (Pelophylax spp.)
Researchers found microplastics in the tissues of anatolian water frogs (Pelophylax spp.) collected from freshwater habitats in Turkey, documenting prevalence and characteristics of plastic particles in these amphibians whose populations are already stressed by multiple environmental pressures.
Spatiotemporal distribution of microplastics in true frogs (Ranidae:Pelophylax) populations from Türkiye
Researchers examined preserved frog stomach contents from 146 true frogs collected across Turkey and found microplastics in nearly 60% of individuals, with plastic fibers being the most common form. The findings show that frogs — which live both in water and on land — are useful indicators of microplastic contamination across multiple ecosystems, and that exposure has been occurring for decades.
Microplastic contamination and ecological risk assessment in two tree frog species (Hyla orientalis and Hyla savignyi) across Türkiye
Researchers examined microplastic contamination in the gastrointestinal tracts of two tree frog species across 24 provinces in Turkiye. The study found 192 microplastic particles total, predominantly PET fibers, with significant geographic variation in contamination levels and microplastic characteristics, suggesting widespread environmental distribution of microplastic pollution across the region.
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.
First record of microplastic contamination in adult endemic amazonian anuran species
For the first time, researchers documented microplastic contamination in two frog species found only in the Amazon, examining their digestive, respiratory, and skin systems. Both species had significant microplastic contamination, with the skin and digestive tract showing the highest levels. This study is important because it shows microplastics have reached even remote Amazonian ecosystems and are contaminating amphibians, which serve as indicators of overall environmental health.
Spatiotemporal variation in the ingestion of microplastics in aquatic and terrestrial salamanders endemic to Türkiye
Researchers examined microplastic ingestion in both aquatic and land-dwelling salamander species across Turkey. They detected microplastics in about 34% of the 232 salamanders studied, with juvenile animals showing higher concentrations than adults, and fiber-shaped particles being most common. The study suggests that microplastic contamination affects amphibians regardless of whether they live in water or on land, indicating the pervasive reach of this pollution.
Microplastic contamination in the gastrointestinal tracts of the Caucasian toad and its habitat at Karagöl Lake, Türkiye
Researchers examined microplastic contamination in Caucasian toads and their lake habitat in a protected area of Turkey. They found that nearly half the toads contained microplastics in their digestive tracts, mainly fibers likely linked to textile and recreational activities. The study shows that even remote, high-altitude environments are not safe from microplastic pollution, underscoring the need for monitoring in amphibian habitats.
Microplastic accumulation in a lizard species: Observations from the terrestrial environments
Researchers examined 152 snake-eyed lizards from 18 populations in Turkey and found microplastics in the digestive tracts of about 22% of them. Fibers and fragments were the most common types, likely coming from synthetic textiles and plastic waste in the lizards' habitats. This is one of the first studies showing that microplastic contamination has spread to terrestrial reptiles, meaning land-based food chains are also affected.
Microplastic ingestion by tadpoles of pond-breeding amphibians—first results from Central Europe (SW Poland)
This study found microplastics in the guts of tadpoles from five amphibian species collected from eight ponds in southwestern Poland, identifying polyethylene and polypropylene as the most common polymer types. The detection of microplastics in freshwater amphibian larvae in Central European ponds confirms that plastic pollution has reached small, inland water bodies and is affecting early developmental stages of amphibians.
Characterization of microplastic pollution in tadpoles living in small water-bodies from Rize, the northeast of Turkey
Researchers characterized microplastic pollution in tadpoles (Pelophylax ridibundus and Rana macrocnemis), sediments, and surface water from small water bodies in northeastern Turkey, finding MPs across all compartments with tadpole tissue containing 302.62-306.69 items per gram. PET, nylon, and polyacrylic were the dominant polymers in tadpoles, while PP and PE dominated sediments, highlighting microplastic transfer across freshwater and terrestrial habitats.
Microplastic footprints in marsh frogs (Pelophylax ridibundus) from two Turkish lakes
Researchers examined microplastic contamination in marsh frogs and their habitats at two Turkish lakes with different levels of human activity. Microplastics were found in frog digestive tracts, water, and sediment at both locations, with fibers being the most common particle type. The lake near higher human activity showed greater contamination, suggesting that urbanization and human presence are significant drivers of freshwater microplastic pollution.
Microplastic Contamination of the Turkish Worm Lizard (Blanus strauchi Bedriaga, 1884) in Muğla Province (Türkiye)
Researchers examined the Turkish worm lizard (Blanus strauchi) for microplastic contamination, finding MPs in digestive tract contents and providing the first evidence of microplastic ingestion in this fossorial reptile species from a Mediterranean habitat.
Occurrence of microplastics in the gastrointestinal tracts of some edible fish species along the Turkish coast
Researchers examined the gastrointestinal tracts of 243 individual fish from five edible species along the Turkish coast, documenting the occurrence and characteristics of ingested microplastics. The study found microplastics present in multiple commercially important fish species, raising implications for seafood safety and human dietary exposure.
Microplastics pollution in larvae of toads, frogs and newts in anthropopressure gradient
Researchers examined microplastic contamination in the larvae of toads, frogs, and newts across sites with varying levels of human activity in Poland. They found microplastics in larvae at all locations, with higher concentrations near urban and agricultural areas compared to natural habitats. The study raises concerns about how microplastic exposure during sensitive developmental stages may affect already-declining amphibian populations.
Hazard assessment of microplastics and heavy metals contamination in Levant frogs (Pelophylax bedriagae): A bioindicator in Western Iran
Scientists examined frogs from 16 locations in western Iran and found microplastics and heavy metals in their digestive tracts, confirming these animals are useful indicators of environmental contamination. Fibers were the most common microplastic type found, mainly from polyethylene and polypropylene. The study shows that microplastic pollution has reached freshwater habitats in Iran and is being ingested by amphibians that are part of broader food webs.

Researchers found microplastics in 19.35% of Apathya cappadocica lizards examined in Türkiye, with 27 total particles detected, predominantly fibers in navy blue, red, and black colors ranging from 50 to 1,727 micrometers, marking one of the first records of microplastic ingestion in this endemic reptile species.
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.

Researchers conducted the first study on microplastic ingestion by terrestrial herpetofauna in southwestern Paraguay, finding microplastics in three species including Rhinella diptycha toads, Hemidactylus mabouia geckos, and a Tropidurus lizard species collected between 2019 and 2020.
Microplastic Pollution at Different Trophic Levels of Freshwater Fish in a Variety of Türkiye`s Lakes and Dams
This study surveyed microplastic contamination in seven freshwater fish species from lakes and reservoirs across Türkiye, finding microplastic particles in the gastrointestinal tracts of all 406 fish examined. All ingested microplastics were fibres, predominantly blue in colour, suggesting textile sources. The broad geographic scope and 100% prevalence across species and water bodies indicate that microplastic contamination of freshwater fish is widespread throughout Türkiye, with implications for human exposure through fish consumption.
Microplastic ingestion in invasive mosquitofish (Gambusia holbrooki): a nationwide survey from Türkiye
Researchers conducted a nationwide survey of microplastic ingestion in 621 invasive mosquitofish across 24 freshwater sites in Turkey. They found that fibers were the dominant particle shape at 66%, with PET and polyethylene being the most common polymer types, and that fish from sites with higher anthropogenic pressure contained more microplastics. The study provides large-scale evidence that freshwater fish widely ingest microplastics, with contamination levels reflecting local human activity.
