“…Ecotoxicological effects of MPs/NPs on marine phyto/zooplanktons, invertebrates, and plants are widely documented [20][21][22][23][24][25][26][27][28][29][30], and have been recently reviewed [5,[31][32][33]. MPs/NPs could also be ingested and accumulated in larger marine fauna by trophic transfer from prey to predator, as demonstrated earlier with invertebrates, such as mussel-consuming crabs [34].…”

Fragmented or otherwise miniaturized plastic materials in the form of micro- or nanoplastics have been of nagging environmental concern. Perturbation of organismal physiology and behavior by micro- and nanoplastics have been widely documented for marine invertebrates. Some of these effects are also manifested by larger marine vertebrates such as fishes. More recently, possible effects of micro- and nanoplastics on mammalian gut microbiota as well as host cellular and metabolic toxicity have been reported in mouse models. Human exposure to micro- and nanoplastics occurs largely through ingestion, as these are found in food or derived from food packaging, but also in a less well-defined manner though inhalation. The pathophysiological consequences of acute and chronic micro- and nanoplastics exposure in the mammalian system, particularly humans, are yet unclear. In this review, we focus on the recent findings related to the potential toxicity and detrimental effects of micro- and nanoplastics as demonstrated in mouse models as well as human cell lines. The prevailing data suggest that micro- and nanoplastics accumulation in mammalian and human tissues would likely have negative, yet unclear long-term consequences. There is a need for cellular and systemic toxicity due to micro- and nanoplastics to be better illuminated, and the underlying mechanisms defined by further work.

“…BaP is ubiquitously distributed in coastal and offshore environments (Antunes et al, 2013;Liu et al, 2015;Châtel et al, 2017), and PAHs including BaP are known to adsorb at high rates to different types of MPs in seawater, particularly to PE (Rochman et al, 2013a;Ziccardi et al, 2016;Schönlau et al, 2019). Furthermore, BaP adsorbed to MPs has been documented to be transferred via trophic transfer to biota (Batel et al, 2016(Batel et al, , 2018Bour et al, 2018;O'Donovan et al, 2018;Pittura et al, 2018).…”

As wide-spread pollutants in the marine environment, microplastics (MPs) have raised public concern about potential toxic effects in aquatic organisms, and, among others, MPs were suspected to act as a vector for organic pollutants to biota. The purpose of the present study was to investigate effects by three model pollutants, oxybenzone (BP3), benzo[a]pyrene (BaP), and perfluorooctane sulfonate (PFOS) adsorbed to polyethylene MPs on the basis of a standard assay, the acute fish embryo toxicity test (FET; OECD TG 236) with zebrafish (Danio rerio) supplemented by additional endpoints such as induction of ethoxyresorufin-O-deethylase (EROD) activity, modification of cyp1a gene transcription and changes in larval swimming behavior. FET assays were performed in three laboratories using slightly different husbandry and exposure conditions, which, however, were all fully compatible with the limits defined by OECD TG 236. This allowed for testing of potential changes in the FET assay due to protocol variations. The standard endpoints of the FET (acute embryotoxicity) did not reveal any acute toxicity for both virgin MPs and MPs spiked with BP3, BaP, and PFOS. With respect to sublethal endpoints, EROD activity was increased after exposure to MPs spiked with BP3 (3 h pulse) and MPs spiked with BaP (96 h continuous exposure). Cyp1a transcription was increased upon exposure to MPs spiked with BP3 or BaP. For the selected combination of MPs particles and contaminants, the basic FET proved not sensitive enough to reveal effects of (virgin and spiked) MPs. However, given that the FET can easily be supplemented by a broad variety of more subtle and sensitive endpoints, an enhanced FET protocol may provide a relevant approach with developmental stages of a vertebrate animal model, which is not protected by current EU animal welfare legislation (Directive EU 2010/63).

“…Microplastics in seawater accumulate passively at oceanographic features, such as eddies, but are also found concentrated along coastlines with high human population-densities and industrial centers (Wright et al, 2013). In contrast, microplastics can accumulate in sediments by being buried beneath sand or rocks after settling from the water column as they become less buoyant over time or are submerged by fouling organisms (Barnes et al, 2009;Cole et al, 2011;Bour et al, 2018). Again, microplastics adhere to the surface of macroalgae (Bhattacharya et al, 2010;Gutow et al, 2016) or can be deposited within dense clusters at low flow.…”

“…The adherence of microplastics to the surface of macroalgae can inhibit photosynthesis and trigger an oxidative stress response, though this was recorded under microplastic concentrations much higher than those observed in nature (Bhattacharya et al, 2010;Wright et al, 2013). The ingestion or digestion of microplastic leads to a wide range of physiological consequences for herbivorous grazers including decreases in energy reserves (Bour et al, 2018), physical blockages of the gastrointestinal system (Wright et al, 2013), intoxication by persistent organic pollutants (Rochman et al, 2013), translocation into the circulatory system (Browne et al, 2007(Browne et al, , 2008, and disruption of the microbiome (Zettler et al, 2013). Grazers can also suffer reductions in recruitment (Green, 2016) and juvenile growth rates (Lo and Chan, 2018), leading to decreased population biomass that may change the structure of the intertidal community (Green, 2016).…”

“…Microplastics have been documented to adhere superficially to the surface of primary producers, posing a risk to the macroalgal physiology while also incorporating them into food webs (Bhattacharya et al, 2010;Wright et al, 2013). Consumers are at risk of accumulating microplastics by direct consumption (Wright et al, 2013) via misidentification of plastics for prey (Schuyler et al, 2014), which leads to physiological (Wright et al, 2013;Bour et al, 2018;Rochman et al, 2013;Browne et al, 2008;Zettler et al, 2013) and reproductive (Green, 2016;Lo and Chan, 2018) (Green, 2016). In addition to direct consumption, macroscopic primary producers may also facilitate incidental ingestion by herbivorous grazers (Gutow et al, 2016) or secondary attraction to plastics with epiphytic biofilms in larger predators (Savoca et al, 2016).…”

A B S T R A C TToxic chemicals within and adsorbed to microplastics (0.05-5 mm) have the potential to biomagnify in food webs. However, microplastic concentrations in highly productive, coastal habitats are not well understood. Therefore, we quantified the presence of microplastics in a benthic community and surrounding environment of a remote marine reserve on the open coast of California, USA. Concentrations of microplastic particles in seawater were 36.59 plastics/L and in sediments were 0.227 ± 0.135 plastics/g. Densities of microplastics on the surfaces of two morphologically distinct species of macroalgae were 2.34 ± 2.19 plastics/g (Pelvetiopsis limitata) and 8.65 ± 6.44 plastics/g (Endocladia muricata). Densities were highest in the herbivorous snail, Tegula funebralis, at 9.91 ± 6.31 plastics/g, potentially due to bioaccumulation. This study highlights the need for further investigations of the prevalence and potential harm of microplastics in benthic communities at remote locations as well as human population centers.
