“…Several studies have demonstrated dose‐dependent impacts of MP exposure on freshwater fish, though these effects may only occur at a particular MP concentration, suggesting MP thresholds for impact, with the relationship between exposure and impact thus being more complex than a simple linear dose–effect relationship (Lei et al, 2018; Mazurais et al, 2015; Qu et al, 2019; Zhao et al, 2020). MP impacts are often exaggerated when the fish is coexposed to an additional chemical (Banaee et al, 2019; Qiao et al, 2019; Roda et al, 2020), although antagonistic interactions can also occur where MPs modulate the harmful effects of another chemical in the fish, or may also have no interaction at all (Hatami et al, 2019; Oliveira et al, 2013; Wen, Jin, et al, 2018). MP effects may also be life stage‐specific, and are occasionally more detrimental to larval than adult fish, especially when MP exposure affects development (Pannetier et al, 2020).…”

“…Changes to blood composition may result in anaemia, altered immune function and nutrient supply throughout the body (e.g. Hatami et al, 2019; Karami et al, 2016; Roda et al, 2020). MPs in the brain may interfere with the endocrine or central nervous system, which can impact individual growth, body condition, behaviour and/or survival (e.g.…”

Microplastics in freshwater fishes: Occurrence, impacts and future perspectives

et al. 2021

Microplastics (MPs) are small, plastic particles of various shapes, sizes and polymers.Although well studied in marine systems, their roles and importance in freshwater environments remain uncertain. Nevertheless, the restricted ranges and variable traits of freshwater fishes result in their communities being important receptors and strong bioindicators of MP pollution. Here, the current knowledge on MPs in freshwater fishes is synthesized, along with the development of recommendations for future research and sample processing. MPs are commonly ingested and passively taken up by numerous freshwater fishes, with ingestion patterns often related to individual traits (e.g. body size, trophic level) and environmental factors (e.g. local urbanization, habitat features). Controlled MP exposure studies highlight various effects on fish physiology, biochemistry and behaviour that are often complex, unpredictable, species-specific and nonlinear in respect of dose-response relationships.Egestion is typically rapid and effective, although particles of a particular shape and/ or size may remain, or translocate across the intestinal wall to other organs via the blood. Regarding future studies, there is a need to understand the interactions of MP pollution with other anthropogenic stressors (e.g. warming, eutrophication), with a concomitant requirement to increase the complexity of studies to enable impact assessment at population, community and ecosystem levels, and to determine whether there are consequences for processes, such as parasite transmission, where MPs could vector parasites or increase infection susceptibility. This knowledge will determine the extent to which MP pollution can be considered a major anthropogenic stressor of freshwaters in this era of global environmental change.

Exposure to xenobiotics such as Yersinia ruckeri can significantly affect bacterial infections in fish. Microplastics (MPs) may predispose fish to infection and act as carriers in pathogen transmission. Therefore, this study is designed to evaluate MPs' effect on damage caused by exposure to Y. ruckeri in rainbow trout. In this study, blood biochemical parameters and hepatic oxidative biomarkers as clinical signs were measured in the fish co-exposed to Y. ruckeri (5 and 10% LD50) and MPs (500 and 1000 mg Kg-1) for 30 days. There were no significant changes in the creatinine, triglyceride, cholesterol levels, and glutamic-pyruvic transaminase activity in the blood of fish infected with Y. ruckeri. In contrast, exposure to MPs had a significant effect on most clinical parameters. The total protein, albumin, globulin, total immunoglobulins, High-density lipoprotein, low-density lipoprotein, cholesterol levels, and γ-glutamyltransferase activity decreased, whereas glucose, triglyceride, and creatinine levels, and glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, alkaline phosphatase, and lactate dehydrogenase activities increased in the plasma of fish after co-exposure to MPs and Y. ruckeri. Dietary MPs combined with a bacterial challenge decreased catalase activities, glutathione peroxidase, and total antioxidant levels. However, the superoxide dismutase activity and malondialdehyde contents in the hepatocytes increased in the hepatocyte of fish co-exposed to MPs and Y. ruckeri. In conclusion, this study showed that fish exposure to MPs and simultaneous challenge with Y. ruckeri could have a synergistic effect on clinical parameters.

“…With LC 50 values > 100 mg/L, PEGs (200 Da-400,000 kDa) were shown to lack acute toxicity to a number of fish species (Table S9). In a prolonged acute fish test, concentrations of 5 and 10 mg/L of PEG (400 Da) did not affect survival of carp (Cyprinus carpio) during a 21-day exposure [132]. Data on chronic effects of PEGs on fish were not available.…”

Environmental fate and effects of water-soluble synthetic organic polymers used in cosmetic products

Because of their usually high molecular weight, polymers are generally considered as being of low environmental concern and are, therefore, exempted from registration and evaluation within REACH. This exemption is currently being reviewed by the European Commission. Against this background, data on the environmental fate and effects of selected water-soluble synthetic organic polymers used in cosmetic products were evaluated. The considered polymers include non-ionic polyethylene glycols (PEGs), anionic homo- and copolymers of acrylic acid (AA-P&CoPs), and cationic polyquaterniums (PQs). The PEGs are more amenable to biodegradation than the AA-P&CoPs and the PQs, which biodegrade slowly. In wastewater treatment plants, sorption and precipitation are expected to lead to an effective removal of the considered polymers from the wastewater. Uptake and bioaccumulation in aquatic organisms are limited by the large molecular size and, for AA-P&CoPs and PQs, the ionic charge of the polymers. In aquatic ecotoxicity tests, the PEGs and the AA-P&CoPs showed generally no to low toxicity. Effects of AA-P&CoPs on algae and crustaceans are attributed to the chelation of cationic nutrients in soft water, with toxicity being mitigated at higher water hardness. Toxicity of the cationic PQs to aquatic organisms ranged from absent to high, depending on the polymer structure, charge density and molecular weight, as well as on the test organism and test conditions. The observed effects most likely result from interactions with the organisms’ surfaces. Aquatic toxicity of the PQs is reduced by dissolved organic carbon, suspended solids, sediments minerals, and at higher water hardness, representative of natural conditions. Results from toxicity tests with sediment and soil organisms were only identified for homopolymers of acrylic acid, showing no toxicity. The evaluation of the available ecotoxicity data suggests that test methods may need to be adapted to the respective polymer type, and further standardised to improve reproducibility. Based on the identified data, the considered polymers are likely to be of low environmental concern. However, this conclusion must be seen as preliminary, since environmental concentrations could not be estimated, and further ecotoxicity data are required, e.g., for sediment and soil organisms.
