“…The abundance of nano-sized plastic materials in the aquatic environment is continuously increasing with the increasing use of plastic materials and their environmental degradation via physical, chemical, and biological processes [1][2][3]. Concerns about their possible ecotoxicological implications are increasing [4,5]. Hence, the comprehensive understanding of their behavior, bioaccumulation, and toxicity potential is highly sought.…”

“…Indeed, important advancements in the knowledge of the fate and impact of nano-sized plastics in marine systems have been already achieved, as recently reviewed [6,7]. However, similar studies dealing with freshwater ecosystems are rather limited [1,4,5,8,9], despite the fact that freshwaters such as lakes are considered to be highly heterogeneous sinks of plastics.…”

“…The existing literature on the toxic effect of different micro-and nano-sized plastic materials towards freshwater organisms was recently reviewed [4,5,[16][17][18], evidencing both acute and chronic effects in algae, ciliates, crustaceans, and fish. For the cladoceran Daphnia magna, used as a freshwater zooplankton model in the present work, both acute and chronic effects were found upon exposure to NPLs of different size and surface functionalization [14,16,[19][20][21][22][23][24][25][26][27].…”

“…The presence of humic acid reduced the acute toxicity of these PS NPLs with different functional groups and charges to D. magna [29]. However, despite recent progress, systematic studies on the role of nano-sized plastics and their behavior and possible effects in freshwaters are still missing, despite the fact that they are recognized as central for their ecological and ecotoxicological outcome [3][4][5][6]18].…”

Concerns about the possible ecotoxicological implications of nano-sized plastic materials in the freshwater environment are growing with the increasing use of plastic materials. The present study focuses on the behavior and effects of amidine-functionalized polystyrene (NPLs) of 20, 40, 60, and 100-nm-size in freshwaters and different synthetic media. Daphnia magna was exposed to increasing concentrations from 0.5 to 30 mg/L (and from 0.5 to 100 mg/L for 100-nm-sized NPLs). The results revealed no significant aggregation in ultra-pure water, culture media, and synthetic water. In the presence of natural organic matter, NPLs of 20 and 40 nm displayed better stability in both freshwater and synthetic media, whereas a significant aggregation of 60 and 100 nm PS NPLs was found. All the studied PS NPLs with size between 20 and 100 nm exhibited acute toxicity to D. magna. The observed 48-h immobilization strongly depended on the primary size of PS NPLs, with 20 and 40-nm-size PS NPLs inducing a stronger effect in both freshwaters and synthetic media. Water quality variables such as pH, cation and anion composition, and DOC were of secondary importance. The results of the present study confirmed the toxicity of NPLs of different sizes to crustaceans in natural freshwater and synthetic media and demonstrated the importance of the primary size of NPLs in the behavior and effects of NPLs.

“…The most abundant MPs type were fibers (65%), followed by films (26.5%), and the remaining MPs were fragments. In our study, fibers suspected to be of plastic origin were found in the whole body samples (digested in 10% KOH solution for 72 h at 40°C) and in the gastrointestinal tract (digested in 4% NaClO solution at room temperature overnight) (Fig 2b Still, the total number of field studies is relatively low (n = 76) compared to laboratory studies (KUKKOLA et al, 2021). Therefore, this study is of great importance, because protocols for the extraction of microplastics were conducted on the tissues and whole-body samples of wild fish specimens.…”

The presence of microplastics (MPs) in the gastrointestinal tract, muscle, and whole-body samples of common bleak Alburnus alburnus L. from Gruža Reservoir (Central Serbia) was studied for the first time. Different protocols for MPs extraction were applied to determine the most efficient one. The study aimed to modify existing protocols to be cost-effective, efficient in digestion, and with no detrimental effect on potentially present MPs polymers. In this study, the digestion with 10% KOH during 48 h at 40°C was efficient for the gastrointestinal tract and muscle. Digestion with 10% KOH during 72 h at 40°C was the most efficient for whole-body samples. The usage of NaClO proved successful in digestion of the gastrointestinal tract overnight at room temperature. Fibers detected in the samples are assumed to be of plastic origin. The general goal was to establish a protocol for extracting MPs from fish tissue in wild populations to obtain results and determine the degree of pollution.

Microplastic categorization schemes are diverse, thereby posing challenges for cross-study comparisons. Further, categorization schemes are not necessarily aligned with and, thus, useful for applications such as source reduction initiatives. To address these challenges, we propose a hierarchical categorization approach that is "fit for purpose" to enable the use of a scheme that is tailored to the study's purpose and contains categories, which, if adopted, would facilitate interstudy comparison. The hierarchical categorization scheme is flexible to support various study purposes (e.g., to support regulation and toxicity assessment) and it aims to improve the consistency and comparability of microplastics categorization. Categorization is primarily based on morphology, supplemented by other identification methods as needed (e.g., spectroscopy). The use of the scheme was illustrated through a literature review aimed at critically evaluating the categories used for reporting microplastic morphologies in North American freshwater environments. Categorization and grouping schemes for microplastic particles were highly variable, with up to 19 different categories used across 68 studies, and nomenclature was inconsistent across particle morphologies. Our review demonstrates the necessity for a "fit for purpose" categorization scheme to guide the information needs of scientists and decision-makers for various research and regulatory objectives across global, regional, and local scales.
