“…Biological samples (periphyton, macroinvertebrates, tadpoles, digestive tracts from adult frogs) were pretreated and sonicated as described in detail in Bertoli et al [16]. Briefly, the Creon enzyme (Creon 40,000 at 20 mg per g of tissue; TRIS-buffered pH at 8.00; 37 • C; Mylan, Italia S.r.l, Milano, Italy) was selected as a digestion technique since it allows the removal of the tissue without affecting the identification of plastic polymers.…”

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.

“…Terrestrial and freshwater and ecosystems are recognized as sources of plastics for the oceans. However, studies on MPs in such ecosystems are still scant to date [16]. This reflected a greater extent for mountain ecosystems, which provide a habitat for numerous species (i.e., insects and amphibians), many of which are endangered [17].…”

“…However, no distinction between direct ingestion of MPs and trophic transfer is apparent considering such field investigations (Duis and Coors, 2016). On the other hand, limited data exists on freshwater organisms' ingestion of microplastic particles in field research studies (Sanchez et al, 2014;Hurley et al, 2017;Nel et al, 2018;Bertoli et al, 2022;Buwono et al, 2022). Furthermore, nanoplastic particles could be transferred trophically up the planktonic food chain through multiple secondary aquatic organisms at the higher trophic level.…”

Micro(nano)plastics Prevalence, Food Web Interactions, and Toxicity Assessment in Aquatic Organisms: A Review

et al. 2022

Plastic pollution is a fast-rising environmental catastrophe. Microplastics and nanoplastics (MNPs) are ubiquitous components of most aquatic environments, and their burgeoning prevalence is endangering aquatic organisms. Recent studies have documented the entanglement of marine and freshwater biota by plastic litters, particularly ghost fishing gear, resulting in suffocation, drowning, or starving to death. Numerous reports have shown that aquatic organisms readily ingest and accumulate these emerging contaminants in their digestive systems. Given experimental evidence that contaminants-laden MNPs can persist in the gastrointestinal tract for considerable durations, investigations have documented a high probability of lethal and sublethal toxicological effects associated with direct and indirect MNPs ingestions. These include chronic protein modulation, DNA damage, embryotoxicity, gastrointestinal toxicity, genotoxicity, growth inhibition toxicity, histopathotoxicity, liver toxicity, neurotoxicity, oxidative stress, reproductive toxicity, and tissue damage. Today, reports have proven the transfer of MNPs across the aquatic food web to humans. However, the mechanisms of multiple contaminants-laden MNPs-induced toxicities, size-dependent toxicity, and the comprehensive mode-of-action and alterations of digestive, reproductive, and neurological systems’ functionality in marine organisms are still unclear. Thus, this review mainly addresses the prevalence, food web interactions, and toxicity assessment of micro(nano) plastics in marine and freshwater organisms. It summarizes documented studies based on the following broad objectives: (1) the occurrence and prevalence of micro(nano) plastic particles in marine and freshwater environments; (2) the ingestion of MNPs by aquatic biota and the food web exposure routes and bioaccumulation of contaminated MNPs by higher trophic entities; (3) the adsorption and desorption of persistent organic pollutants, metals, and chemical additives on/from micro(nano)plastics; and (4) the probable ecotoxicological effects of micro(nano)plastics ingestion on aquatic biota.

“…Driscoll et al, 2021 also investigated the presence of MPs in 32 individuals of Gammarus lacustris and observed the presence of MP in only single individual (Driscoll et al 2021). The largest study was carried out on 2772 individuals from 33 taxa, among which 48.5% organism had MPs in their body, the highest numbers of MPs were reported in the collector-gatherers and predators (Bertoli et al 2022) In mollusks, highest numbers of MPs were found in Anadara granosa which was 180.6 ± 21.22 MPs per individual in which bers were the most dominant type of MPs followed by fragments and lms (Fitri &Patria 2019). In a similar study on Gammarous setosu, fragments and bers were the dominant types of MPs with the average contamination of 72.5 MPs per individual (Iannilli et al 2020).…”

Plastic wastes in the environment ultimately reach to the aquatic habitats and becomes available to aquatic organisms. The pathway of microplastic in aquatic system is very less investigated specially in freshwater systems. There have been evidences of MPs ingestion by freshwater biota but the fate of these MPs further in the food chain is unexplored. Thus, we reviewed the status of MPs in freshwater biota and tried to compare the available studies to merge the available information, concepts and perspectives in order to draw a conclusion on bioaccumulation potential, trophic transfer possibilities, biomagnification and trends of ingesting MPs by the biota. In this review the previously available information about MPs in aquatic biota is arranged, analyzed and interpreted to understand all possible route of MPs in freshwater habitats. The review further provides a better understanding about the lack of information and research gaps that are needed to be investigated further to develop a solution to problem of MPs in future
