“…Studies investigating animal's behavior are of extreme importance to draw conclusions about potential effects on ecosystem function. There are many relevant species for ecosystem function that need scientific attention (Rochman 2016;Wieczorek et al 2018), such as different functional groups of fishes (Vendel et al 2017).…”

Plastic has become indispensable for human life. When plastic debris is discarded into waterways, these items can interact with organisms. Of particular concern are microscopic plastic particles (microplastics) which are subject to ingestion by several taxa. This review summarizes the results of cutting-edge research about the interactions between a range of aquatic species and microplastics, including effects on biota physiology and secondary ingestion. Uptake pathways via digestive or ventilatory systems are discussed, including (1) the physical penetration of microplastic particles into cellular structures, (2) leaching of chemical additives or adsorbed persistent organic pollutants (POPs), and (3) consequences of bacterial or viral microbiota contamination associated with microplastic ingestion. Following uptake, a number of individual-level effects have been observed, including reduction of feeding activities, reduced growth and reproduction through cellular modifications, and oxidative stress. Microplastic-associated effects on marine biota have become increasingly investigated with growing concerns regarding human health through trophic transfer. We argue that research on the cellular interactions with microplastics provide an understanding of their impact to the organisms' fitness and, therefore, its ability to sustain their functional role in the ecosystem. The review summarizes information from 236 scientific publications. Of those, only 4.6% extrapolate their research of microplastic intake on individual species to the impact on ecosystem functioning. We emphasize the need for risk evaluation from organismal effects to an ecosystem level to effectively evaluate the effect of microplastic pollution on marine environments. Further studies are encouraged to investigate sublethal effects in the context of environmentally relevant microplastic pollution conditions.

“…It is important to disentangle the risks associated with ingested particles in an ecologically relevant context (Koelmans et al 2017a). In a future of ever smaller particles, many organisms will be confronted with them, regardless of the size of the organism (Mattsson et al 2017;Vendel et al 2017;Critchell and Hoogenboom 2018).…”

“…Among those characteristics, shape, size, surface area, roughness, solubility, surface porosity, and surface chemistry were certified to play important parts in the biological reactivity of MPs . More and more researches have testified that MPs have the ability to transfer into the intestinal tissue of animals, which can induce scratch injuries . Uptake of polystyrene nanoparticles will lead to the accumulation of MPs in the gut, which subsequently resulting in thinning of gut epithelium therefrom promoting inflammatory reaction and oxidative stress .…”

Microplastics (MPs) pollution is a global paradigm that raises concern in relation to environment and human health. In order to investigate the molecular toxicity mechanisms of MPs, transcriptomic analyses were performed on in vitro Caco‐2 cell model. After observing that polystyrene microplastics (PS‐MPs) decreased cell viability in a dose‐dependent manner, the responsible genes and involved pathways that might make contribution to PS‐MBs‐induced toxicity to Caco‐2 cells were identified with Illumina RNA seq. A total of 442 genes including, 210 up‐regulated ones and 232 down‐regulated ones, showed differential expression after treatment by PS‐MPs with a concentration of 12.5 mg L−1 or 50.0 mg L−1 for 24 hours. Gene Ontology (GO) annotation enriched unigenes can be grouped into three separated clusters: cellular component (CC), biological process (BP), and molecular function (MF). The dominate pathways related to NF‐κB, MAPK signaling, cytokine‐cytokine receptor interaction, and toll‐like receptor were strongly influenced by PS‐MBs. These pathways are involved in modulating cell inflammatory and proliferation. The qPCR were applied to investigate the transcriptional level of five proliferation related genes (Ras, ERK, MER, CDK4, Cyclin D1) and four inflammation related genes (TRPV1, iNOS, IL‐1β, IL‐8), and the results were consistent with RNA‐seq data. This study has provided new insight into the understanding of the toxicity effects of PS‐MBs‐induced intestinal inflammatory diseases.

“…Similarly, European commercial fishes sampled from the North Sea and the English Channel demonstrated an overall microplastic ingestion of 2.6% and 36.5%, respectively (Foekema et al 2013;Lusher et al 2013). Plastic ingestion in fishes occurs across a wide variety of feeding types or guilds, and this grouping may offer important insights on predicting microplastic accumulation in fish (Vendel et al 2017;McNeish et al 2018). Different feeding strategies among species as well as the heterogeneous distribution of plastics in the environment likely account for some of these observations (Lusher et al 2017;Peters et al 2017).…”

As global seafood consumption rises, it is important to understand the mechanisms by which fisheries are affected by microplastic pollution. A growing body of literature describes the occurrence and effects of microplastics in commercial species, primarily from Europe, Asia, and South America; however, there are far fewer studies conducted in North America. In this article, we review the evidence available for the presence and effects of microplastics on commercially valuable fishery species of North America and possible consequences of human consumption. We identify key priorities for future research on this topic including geographic and taxonomic representativeness; physiological, organismal, and population level effects; microplastics as multiple stressors; human health risks; and standardization of field and lab protocols. AbstractCommercial fisheries yield essential foods, sustain cultural practices, and provide widespread employment around the globe. Commercially harvested species face a myriad of anthropogenic threats including degraded habitats, changing climate, overharvest, and pollution. Microplastics are pollutants of increasing concern, which are pervasive in the environment and can harbor or adsorb pollutants from surrounding waters. Aquatic organisms, including commercial species, encounter and ingest microplastics, but there is a paucity of data about those caught and cultured in North America. Additional research is needed to determine prevalence, physiological effects, and population-level implications of microplastics in commercial species from Canada,
