“…Within controlled experimental studies, freshwater fish MP exposure levels have been highly variable, based on the type, size and shape of MPs, and, taking weight alone, span at least five orders of magnitude from 10 µg/L (Qiao et al, 2019) up to 6 g/L (LaPlaca & van den Hurk, 2020). While these exposure levels are largely within the variation of recorded freshwater environmental loads (e.g.…”

“…Li, Busquets, et al, 2020; Li et al, 2018; Tibbetts et al, 2018), some higher exposure levels can be considered ecologically irrelevant based on these current freshwater data (e.g. LaPlaca & van den Hurk, 2020; Mazurais et al, 2015). Several studies have replicated specific environmental MP loadings appropriate to the life stage and habitat of the model fish (e.g.…”

“…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. Athey et al, 2020; LaPlaca & van den Hurk, 2020; Lei et al, 2018; Xia et al, 2020). Functional disruption of key organs, such as the kidneys, liver and brain, can then impact body fluid composition, neurotransmitter and endocrine pathways (Walpitagama et al, 2019; Wang, Wei, et al, 2019), with survival consequences for the individual (Figure 2).…”

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.

“…A recent study found microplastics, including tire particles, in the stomach content of several wild fish species, showing that fish can also ingest TRWP 31 . Studies investigating direct effects of TRWP remain scarce 21,32,33 which highlights the need to investigate the effects of the particles themselves in addition to the effects of leachates 34 . Indeed, several studies showed that the solubilization of polymer-bound chemicals was enhanced in fish gut fluids compared to water and could promote bioaccessibility of the chemicals for uptake into the circulatory system [35][36][37][38][39][40] .…”

Tire and road wear particles (TRWP) account for an important part of the polymer particles released into the environment. There are scientific knowledge gaps as to the potential bioaccessibility of chemicals associated with TRWP to aquatic organisms. This study investigated the solubilization and bioaccessibility of seven of the most widely used tire-associated organic chemicals and four of their degradation products from cryogenically milled tire tread (CMTT) into fish digestive fluids using an in vitro digestion model based on Oncorhynchus mykiss. Our results showed that 0.06% to 44.1% of the selected compounds were rapidly solubilized into simulated gastric and intestinal fluids within a typical gut transit time for fish (3 h in gastric and 24 h in intestinal fluids). The environmentally realistic scenario of coingestion of CMTT and fish prey was explored using ground Gammarus pulex. Coingestion caused compound-specific changes in solubilization, either increasing or decreasing the compounds’ bioaccessibility in simulated gut fluids compared to CMTT alone. Our results emphasize that tire-associated compounds become accessible in a digestive milieu and should be studied further with respect to their bioaccumulation and toxicological effects upon passage of intestinal epithelial cells.

“…The undesired side effects accompanying the leakage of hazardous compounds from rubber crumb to soil and water present another topic that is not covered sufficiently despite the toxicity for various organisms [ 5 , 26 ]. Li et al [ 27 ] analyzed the release of zinc and PAHs from rubber crumbs and concluded that it should be subjected to more detailed studies due to the toxicity of leachates.…”

Environmental Consequences of Rubber Crumb Application: Soil and Water Pollution

End-of-life tires are utilized for various purposes, including sports pitches and playground surfaces. However, several substances used at the manufacture of tires can be a source of concerns related to human health or environment’s adverse effects. In this context, it is necessary to map whether this approach has the desired effect in a broader relation. While the negative effects on human health were investigated thoroughly and legislation is currently being revisited, the impact on aquatic or soil organisms has not been sufficiently studied. The present study deals with the exposure of freshwater and soil organisms to rubber crumb using the analysis of heavy metal and polycyclic aromatic hydrocarbon concentrations. The obtained results refer to substantial concerns related to freshwater contamination specifically, since the increased concentrations of zinc (7 mg·L−1) and polycyclic aromatic hydrocarbons (58 mg·kg−1) inhibit the growth of freshwater organisms, Desmodesmus subspicatus, and Lemna minor in particular. The performed test with soil organisms points to substantial concerns associated with the mortality of earthworms as well. The acquired knowledge can be perceived as a roadmap to a consistent approach in the implementation of the circular economy, which brings with it a number of so far insufficiently described problems.
