“…Plastic represented the main litter category found in the GIT of examined demersal elasmobranchs, as also observed in previous studies on Mediterranean demersal sharks (Anastasopoulou et al, 2013a;Kühn et al, 2020;Cartes et al, 2016;Alomar and Deudero, 2017;Valente et al, 2019;Capillo et al, 2020;Mancia et al, 2020) and on a wide range of marine organisms (Campani et al, 2013;Romeo et al, 2015Romeo et al, , 2016Battaglia et al, 2016;Bernardini et al, 2018;Digka et al, 2018a;Bottari et al, 2019;Savoca et al, 2019Savoca et al, , 2020Schirinzi et al, 2020). G. melastomus and R. clavata ingested only plastics while S. canicula ate also chicken remains (probably used as bait by local artisanal fishermen targeting common octopus) and polyacrylamide The abundance (average number ± standard deviation, SD) and percentage of occurrence (%O) of fibers observed in samples and controls are provided together with the corrected values after application of control procedures.…”

This study aims to assess the litter ingestion in some demersal elasmobranchs, combining a classical gastro-intestinal tract (GIT) analysis with a procedure methodology to reduce airborne fibers contamination. In order to prevent the overestimation of litter ingestion, we applied severe mitigation measures to avoid airborne contamination during the analyses, integrating a new approach for the correction of estimates of fibers abundance using control procedure. In this study, we assessed the anthropogenic litter ingestion in four elasmobranch species from the southern Tyrrhenian Sea: Scyliorhinus canicula (n = 27), Etmopterus spinax (n = 16), Galeus melastomus (n = 12), and Raja clavata (n = 6). The GIT of each specimen was analyzed by visual sorting and the polymers identified by Fourier transform infrared spectroscopy technique. Overall, 19 litter particles were found in the GIT of 13 demersal elasmobranchs (%O = 21) and for the first time, evidence of litter ingestion by R. clavata in Mediterranean waters was also reported. In G. melastomus and R. clavata all anthropogenic particles were plastics, whereas in S. canicula other litter categories were also found. No litter ingestion was instead observed in E. spinax. More than 50% of litter particles belonged to microlitter category (<5 mm). Polyamide was the only polymer typology found in all examined species. We described the procedures to control the airborne contamination applied at each step of laboratory analysis and, thanks to the application of our control method, it was possible to exclude the 95% of fibers found in samples from the assessment. Moreover, we compared fibers abundances observed in samples and controls. This study, combining an approach for minimizing the bias associated to airborne fiber contamination, provided a reliable assessment of marine litter ingestion in demersal elasmobranchs.

“…Generally, signals with strong IR intensity have weak Raman intensity and vice versa. For instance, carbonyl groups, being polar functional groups, are well detected by IR, whereas aromatic bonds and double bonds are better identified using Raman [ 109 ].…”

“…Microplastic fibers were recently detected on the external surface and in the gastrointestinal tract of clupeid fishes (larval and juvenile stages) from the Mediterranean Sea, i.e., Sardina pilchardus (0.53 items/specimen) and Engraulis encrasicolus (0.26 items/specimen). Since these clupeids are among the main food sources for several marine species, these results give rise to concern relating to the possible transfer of microplastics through the marine food web and into humans [ 109 ].…”

Recently, studies on microplastics (MPs) have increased rapidly due to the growing awareness of the potential health risks related to their occurrence. The first part of this review is devoted to MP occurrence, distribution, and quantification. MPs can be transferred from the environment to humans mainly through inhalation, secondly from ingestion, and, to a lesser extent, through dermal contact. As regards food web contamination, we discuss the microplastic presence not only in the most investigated sources, such as seafood, drinking water, and salts, but also in other foods such as honey, sugar, milk, fruit, and meat (chickens, cows, and pigs). All literature data suggest not-negligible human exposure to MPs through the above-mentioned routes. Consequently, several research efforts have been devoted to assessing potential human health risks. Initially, toxicological studies were conducted with aquatic organisms and then with experimental mammal animal models and human cell cultures. In the latter case, toxicological effects were observed at high concentrations of MPs (polystyrene is the most common MP benchmark) for a short time. Further studies must be performed to assess the real consequences of MP contamination at low concentrations and prolonged exposure.

“…Since microplastics (MPs) and nanoplastics (NPs) ingestion by aquatic organisms is reported by laboratory and field studies with a regard to commercial species too [36][37][38], an unavoidable concern is whether MPs and NPs, one ingested by fish, can be absorbed by the gastrointestinal (GI) tract and can pass into other body districts. However, this field of knowledge just started to be investigated recently.…”

Micro and Nano Plastics Distribution in Fish as Model Organisms: Histopathology, Blood Response and Bioaccumulation in Different Organs

Micro- and nano-plastic (MP/NP) pollution represents a threat not only to marine organisms and ecosystems, but also a danger for humans. The effects of these small particles resulting from the fragmentation of waste of various types have been well documented in mammals, although the consequences of acute and chronic exposure are not fully known yet. In this review, we summarize the recent results related to effects of MPs/NPs in different species of fish, both saltwater and freshwater, including zebrafish, used as model organisms for the evaluation of human health risk posed by MNPs. The expectation is that discoveries made in the model will provide insight regarding the risks of plastic particle toxicity to human health, with a focus on the effect of long-term exposure at different levels of biological complexity in various tissues and organs, including the brain. The current scientific evidence shows that plastic particle toxicity depends not only on factors such as particle size, concentration, exposure time, shape, and polymer type, but also on co-factors, which make the issue extremely complex. We describe and discuss the possible entry pathways of these particles into the fish body, as well as their uptake mechanisms and bioaccumulation in different organs and the role of blood response (hematochemical and hematological parameters) as biomarkers of micro- and nano-plastic water pollution.
