“…While not included in the results of this study, fibers were observed tangled within blue crab sample gills. With bivalves, microplastic studies involve digestion of the whole organisms, with the most common digestants being either 30% H 2 O 2 , 10% KOH, or HNO 3 (Li et al ; Van Cauwenberghe et al ; Fang et al ). Some digestants, particularly HNO 3 , can degrade plastic polymers like nylon, which may affect their results (Van Cauwenberghe et al ).…”

Microplastic pollution has been observed in marine environments around the world and has the potential to negatively impact marine organisms if ingested. Blue crabs (Callinectes sapidus) are susceptible to this pollution because they feed in sediment where dense plastics accumulate. Microplastic ingestion by blue crabs was assessed in Corpus Christi Bay, TX. Crab stomachs were extracted and digested using a hydrogen‐peroxide based tissue destruction method followed by material confirmation using microattenuated total reflectance Fourier transform infrared spectroscopy (μ‐FTIR). From the 39 blue crabs sampled, 28 fully synthetic fragments and fibers and 24 semisynthetic fibers were found within their stomachs. After correcting for possible contamination, 36% of collected blue crabs contained fully synthetic fragments and fibers and semisynthetic fibers with an estimate of 0.87 items per crab. This study demonstrates the need for further studies that assess the impacts of plastic ingestion on blue crabs.

“…24 Other studies have also proven the occurrence and accumulation of large plastic items in the deep sea, 25−27 and recently published data show that plastic objects have been ingested by animals of the benthic zone, assuming a sedimentation behavior of the plastic particles. 28,29 Sedimentation of plastic particles is only possible if the density of plastics is higher than that of seawater (which is the case for roughly a third of all polymers produced) or if they become negatively buoyant by the formation of biofilms and adherence to other particles. 30−33 The smaller the particles are, the faster they can reach their critical sinking density.…”

On account of environmental concerns, the fate and adverse effects of plastics have attracted considerable interest in the past few years. Recent studies have indicated the potential for fragmentation of plastic materials into nanoparticles, i.e., "nanoplastics," and their possible accumulation in the environment. Nanoparticles can show markedly different chemical and physical properties than their bulk material form. Therefore possible risks and hazards to the environment need to be considered and addressed. However, the fate and effect of nanoplastics in the (aquatic) environment has so far been little explored. In this review, we aim to provide an overview of the literature on this emerging topic, with an emphasis on the reported impacts of nanoplastics on human health, including the challenges involved in detecting plastics in a biological environment. We first discuss the possible sources of nanoplastics and their fates and effects in the environment and then describe the possible entry routes of these particles into the human body, as well as their uptake mechanisms at the cellular level. Since the potential risks of environmental nanoplastics to humans have not yet been extensively studied, we focus on studies demonstrating cell responses induced by polystyrene nanoparticles. In particular, the influence of particle size and surface chemistry are discussed, in order to understand the possible risks of nanoplastics for humans and provide recommendations for future studies.

“…By far, Fang et al (2018) provided the most comprehensive investigation of microplastic ingestion by multiple benthic invertebrate species from the Arctic and sub-Arctic regions of the Bering and Chukchi Seas. In this study conducted in 2017, 431 individuals from 11 different speciesincluding bivalves, gastropods, echinoderms and crustaceanswere investigated for the presence of microplastics.…”

Microplastics are increasingly recognized as being globally widespread, but relatively little is known about the presence and abundance of microplastics in samples collected in Polar Regions. Here we review the current knowledge about microplastic occurrence and distribution in polar environments, with a particular focus on the relevance of the data and comparability between Arctic and Antarctic investigations. In the Arctic, microplastics have been found in seawater, marine sediments, ice, and snow and in the gut content of several species at different
