Microplastics (MPs) are ubiquitous in a freshwater, and many fishes amphibians used to eat the plastic fragments from those water bodies by mimicking it as food. Amphibians such frogs play an essential role healthy wetlands ecosystem receiving particular attention recent years especially because of their global decline. However, very few studies have assessed frog's exposure MPs. For this purpose, study is carried out evaluate present different environments Bengal delta Twenty-seven nine species were collected habitats observe MP's abundance then compared based on habitat, length, body weight. MPs found gastrointestinal tract (GIT) 90% frog samples, which relatively higher, other conducted tadpole frogs. The was highest (19 MPs/individual) Asian Common Toad (Duttaphrynus melanostictus). Microscopic analysis through stereo microscope showed that common MP particles fiber-like (84%) most colorless. Fourier Transform Infrared done identify possible polymers within polyamide (PA), polystyrene (PS), acrylonitrile butadiene styrene (ABS) vinyl ethylene-vin acetate (EVA) particles. No significant relation between length weight with abundance. GIT indicates high ecological risk animals delta.

Larger Common River Frogs (Amietia delalandii) have Fewer and Shorter Tissue Microplastic Fibres than Smaller Frogs

Bulletin of Environmental Contamination and Toxicology, Journal Year: 2024, Volume and Issue: 112(2)

Abstract Little is known about microplastics (MPs) in adult frogs. We investigated MPs Common River Frogs ( Amietia delalandii ) from Potchefstroom, South Africa. Five kinds of samples were analysed: natural water, water used to rinse the skin, intestine, and remainder body (corpus). Tissues digested. Microplastics occurred all frogs sample types (1128 counted). Fibres most prevalent MP. Fibre lengths between 28 4300 μm, either polyester or polyvinyl alcohol. skin likely derived ambient, corpus translocation via skin. tissues significantly shorter larger frogs, a phenomenon we provisionally assign situ biodegradation. can potentially be transferred through food web higher trophic levels. This study provides first evidence frog avenues for further investigations. Graphical

Given their pervasiveness in the environment, particularly aquatic ecosystems, plastics are posing a growing concern worldwide. Many vertebrates and invertebrates marine, freshwater, terrestrial ecosystems exhibit microplastic (MP) uptake accumulation. Some studies have indicated fatal impacts of MPs on animals possible transfer through food chains. Thus, it is crucial to study MP pollution its environment-sensitive globally threatened animal groups, such as amphibians, which also play an important role energy between ecosystems. Unfortunately, research this field lacking sources organized information scarce. Hence, we systematically reviewed published literature amphibians fill existing knowledge gap. Our review revealed that most previous focused bioaccumulation whereas, only few highlighted impacts. We found more than 80% studied species exhibited were reported persist different organs for long time get transferred other trophic levels.

Effects of Polyester Microplastic Fiber Contamination on Amphibian–Trematode Interactions

Environmental Toxicology and Chemistry, Journal Year: 2021, Volume and Issue: 41(4), P. 869 - 879

Published: March 8, 2021

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