“…Spectroscopy revealed that all MPs particles had an anthropogenic origin and included a majority of nylon (90%), followed by polyisoprene (6%), polyurethane (2%), and 1,2-polybutadiene (2%). This study confirmed that pond-breeding amphibians are exposed to MPs [58].…”

The world is ever evolving and new technologies are popping up everywhere. New inventions and discoveries have created a better world, but not a sustainable one. The whole earth is drowning in various pollutants and garbage. Plastic pollution has garnered sufficient attention and there are various teams and organizations working toward cleaning our beaches, parks, and environment. However, all these actions will not suffice as plastics have trickled down into microplastics, which are posing a greater threat to our water systems and aquatic fauna. Several ongoing researches focus on marine microplastics, while only 13% of studies are on freshwater. Research on microplastics is now on the rise, with new strategies and restrictions being put into place to curb its accumulation in our marine and freshwater environments. In a recent study, microplastics were found to be present in human blood with. Out of 22 people tested, 17 test subjects had microplastics present in their blood. This review focuses on the adverse effects of microplastics in marine and freshwater ecosystems, with special focus on aquatic fauna.

“…The particle size ranged from 550.91 to 2355.51 µm, and a significant positive correlation between the particle length and frog size was found (Pearson's correlation; r = 0.991, p = 0.001). Presumably, larger frogs catch larger prey, which, in turn, can ingest larger particles [39]. Similarly, Jâms et al [32] found a positive relationship between the animal size and length of ingested plastic, and that body length describes over 40% of the variance in the size of the largest plastic item an animal can ingest.…”

Microplastics Occurrence in the European Common Frog (Rana temporaria) from Cottian Alps (Northwest Italy)

Microplastics (MPs) pollution is arousing growing attention, yet knowledge about its occurrence in amphibians is scant to date. With this study, we aimed to determine whether plastic (>5000 μm) and MPs (10–5000 μm) could be detected in adult Rana temporaria from a high-mountain ecosystem (the Cottian Alps, northwest Italy). To do this, aquatic compartments and the digestive tract of adult R. temporaria were analyzed. Water, sediment, periphyton, aquatic macroinvertebrates, and tadpoles tested negative for plastic and MPs. Microplastics were detected in all the adult frogs (n = 5); all the identified items (one per specimen) were fibers (size range: 550.91–2355.51 µm). A statistically significant positive correlation between the particle length and frog size was recorded. The predominant fiber color was blue. The chemical composition was polyamide (60%), polyethylene (20%), and polyethylene terephthalate (20%). Since both the biotic and the abiotic freshwater compartments (tadpoles included) revealed the absence of MPs, it can be assumed that adult frogs ingest MPs from the surrounding terrestrial environment.

“…Similarly, surveys of anuran habitats in China found 0.48 to 21.52 microplastics L –1 across all shapes and polymer types (Hu et al 2018), suggesting that the reduction of trematode transmission to tadpole hosts via microplastics in nature is likely to be limited. However, to date, the number of surveys that have evaluated microplastic contamination in anuran habitats is low (China: Hu et al 2018; Turkey: Karaoğlu and Gül 2020; Poland: Kolenda et al 2020), making it difficult to compare the relevance of our laboratory concentrations with those in the field.…”

Microplastic contamination poses a global threat to aquatic organisms, yet we know little as to how microplastics may indirectly affect organismal health via their influence on species–species interactions (e.g., host–parasite interactions). This is problematic because microplastic‐mediated alterations to host–parasite dynamics could negatively impact individual‐ population‐level health of hosts. Using a larval amphibian (host) and free‐living trematode (parasite) model, we asked whether 1) polyester microplastic fibers influence parasite survival; 2) whether polyester microplastic fiber ingestion by amphibians alters amphibian susceptibility to infection; and 3) whether simultaneous exposure of amphibians and trematodes to polyester microplastic fibers influences infection outcomes. Polyester microplastic fibers did not alter trematode survival, nor did their ingestion by amphibians increase amphibian susceptibility to infection. However, when amphibians and trematodes were exposed simultaneously to the fibers, the infection success of the parasite was reduced. Lastly, we conducted a field survey for microfiber contamination across multiple ponds and found microfibers across each of the sampled ponds. Overall, our results contribute to the limited knowledge surrounding the ecological consequences of microplastic contamination. Environ Toxicol Chem 2022;41:869–879. © 2021 SETAC
