Uptake, Whole-Body Distribution, and Depuration of Nanoplastics by the Scallop Pecten maximus at Environmentally Realistic Concentrations

Abstract: Previous studies of uptake and effects of nanoplastics by marine organisms have been conducted at what may be unrealistically high concentrations. This is a consequence of the analytical challenges in tracking plastic particles in organisms at environmentally relevant concentrations and highlights the need for new approaches. Here, we present pulse exposures of 14C-radiolabeled nanopolystyrene to a commercially important mollusk, Pecten maximus, at what have been predicted to be environmentally relevant concen… Show more

“…Nevertheless, several laboratory‐based studies have reported translocation of microplastic particles, mostly nanosized plastic, from the gastrointestinal tract into other tissues (Browne et al 2008; Rosenkranz et al 2009; von Moos et al 2012; Farrell and Nelson 2013; Avio et al 2015; Brennecke et al 2015; Mattsson et al 2017; Skjolding et al 2017; Al‐Sid‐Cheikh et al 2018; Chae et al 2018; Ding et al 2018; Pitt et al 2018; Triebskorn et al 2019), implying that when exposure to microplastic particles of a particular size is elevated, translocation from the gastrointestinal tract to internal organs is possible. In some studies, particles coated with a fluorescence dye were used to visually observe the behavior of particles, such as in an early study by Rosenkranz et al (2009).…”

“…Given the research that has been conducted into the bioaccumulation of ENMs, considerable knowledge may already be accessible, and it is recommended that opportunities to build on currently available information should be optimized (Hüffer et al 2017). For instance, 14 C‐labeled polystyrene nanoplastic has recently been employed to study the uptake and depuration of nanosized particles at environmentally relevant concentrations (Al‐Sid‐Cheikh et al 2018). Al‐Sid‐Cheikh et al (2018) observed relatively rapid depuration of the particles, but proposed further research using 14 C‐labeled particles aimed at better characterizing and quantifying the mechanisms of uptake, absorption, and elimination of particles in chronic exposures, which may help us to better understand the fate of biologically ingested particles.…”

“…The majority of studies that do exist, focus on macroorganisms such as mussels ( Mytilus edulis ) and oysters ( Crassostrea virginica ), which have been shown to take up 100 nm polystyrene beads (Ward and Kach, ). Recently, the commercially important mollusc Pecten maximus was shown to uptake polystyrene nanoparticles at environmental concentrations of less than 0.015 ppm (Al‐Sid‐Cheikh et al ., ).…”
