“…For example the blue mussels inhabiting the brackish waters of the Baltic Sea (Mytilus trossulus) are markedly smaller than the blue mussels (Mytilus edulis) inhabiting North Sea and the Danish straits (Väinölä and Strelkov, 2011). Moreover, experimental work with the local zooplankton and benthic communities in the northern Baltic Sea (Setälä et al, 2014(Setälä et al, , 2016 have already shown the efficiency of planktonic and benthic animals to ingest relatively small plastic microspheres of 10 μm in size, which are in the size range of their natural food, phytoplankton and small zooplankton. To better estimate the hazards that microscopic litter particles pose to marine organisms, it is evident that also the smaller fractions should be included in the sampling protocols (Syberg et al, 2015).…”

“…In a laboratory study designed to mimic a coastal ecosystem, Setälä et al. () compared the ingestion of microplastics in marine invertebrates with different feeding habits (bivalves, free‐swimming crustaceans and benthic, deposit‐feeding organisms). Microbeads (10 μm) were ingested by all organisms, with the highest quantities taken up in bivalves ( Mytilus tossulus and Macoma balthica ).…”

Following a request from the German Federal Institute for Risk Assessment (BfR), the EFSA Panel for Contaminants in the Food Chain was asked to deliver a statement on the presence of microplastics and nanoplastics in food, with particular focus on seafood. Primary microplastics are plastics originally manufactured to be that size, while secondary microplastics originate from fragmentation. Nanoplastics can originate from engineered material or can be produced during fragmentation of microplastic debris. Microplastics range from 0.1 to 5,000 μm and nanoplastics from approximately 1 to 100 nm (0.001–0.1 μm). There is no legislation for microplastics and nanoplastics as contaminants in food. Methods are available for identification and quantification of microplastics in food, including seafood. Occurrence data are limited. In contrast to microplastics no methods or occurrence data in food are available for nanoplastics. Microplastics can contain on average 4% of additives and the plastics can adsorb contaminants. Both additives and contaminants can be of organic as well of inorganic nature. Based on a conservative estimate the presence of microplastics in seafood would have a small effect on the overall exposure to additives or contaminants. Toxicity and toxicokinetic data are lacking for both microplastics and nanoplastics for a human risk assessment. It is recommended that analytical methods should be further developed for microplastics and developed for nanoplastics and standardised, in order to assess their presence, identity and to quantify their amount in food. Furthermore, quality assurance should be in place and demonstrated. For microplastics and nanoplastics, occurrence data in food, including effects of food processing, in particular, for the smaller sized particles (< 150 μm) should be generated. Research on the toxicokinetics and toxicity, including studies on local effects in the gastrointestinal (GI) tract, are needed as is research on the degradation of microplastics and potential formation of nanoplastics in the human GI tract.

“…Furthermore, particle fate in exposure systems is seldom investigated thoroughly. In some exposure studies of marine invertebrates particle ingestion has been quantified, most commonly by counting particles in animal tissues or feces (e.g., Watts et al ; Setälä et al ); however, the fate of the remaining particles is rarely determined. This hampers the understanding of how the particles behave and where they end up in the system.…”

We present a blue mussel exposure system where the fate of microplastics (polystyrene beads) is tracked during exposure and depuration phases. This enabled the establishment of a complete mass balance. Quantification of beads in mussels was done with a novel enzymatic digestion protocol. We found a similar relative distribution of beads for 2 environmentally realistic concentrations (5 and 100 beads L−1) and no substantial egestion of particles within 2 h of depuration.
