Low levels of microplastics (MP) in wild mussels indicate that MP ingestion by humans is minimal compared to exposure via household fibres fallout during a meal.

Investigation of Microplastics in Freshwater Mussels (Lasmigona costata) From the Grand River Watershed in Ontario, Canada

Microplastics have been identified as a widespread, persistent environmental pollutant. The investigation of microplastics in marine ecosystems has been prevalent in the literature; however, much

No evidence of spherical microplastics (10–300 μm) translocation in adult rainbow trout (Oncorhynchus mykiss) after a two-week dietary exposure

This research suggests that the consumption of fish fillets may not be a significant exposure pathway for microspheres >10 μm in size to contaminate humans, and suggests that translocation of spherical microplastics of this size range does not occur in adult rainbow trout.

Microplastics in commercial bivalves harvested from intertidal seagrasses and sandbanks in the Ria Formosa lagoon, Portugal

The unexpectedly high number of MPs recorded in the three commercially exploited species suggests that this semi-closed lagoon system is experiencing a higher anthropogenic pressure than are open coastal systems.

Dietary Exposure to Additives and Sorbed Contaminants from Ingested Microplastic Particles Through the Consumption of Fisheries and Aquaculture Products

Microplastics and nanoplastics may be found in the gastrointestinal tract of some aquatic animals and could potentially be ingested by humans if consumed whole. Information on the toxicity of plastic

Accumulation of microplastic on shorelines woldwide: sources and sinks.

It is shown that microplastic contaminates the shorelines at 18 sites worldwide representing six continents from the poles to the equator, with more material in densely populated areas, but no clear relationship between the abundance of miocroplastics and the mean size-distribution of natural particulates.

Uptake and effects of microplastics on cells and tissue of the blue mussel Mytilus edulis L. after an experimental exposure.

Proof of principle is provided that microplastics are taken up into cells and cause significant effects on the tissue and cellular level, which can be assessed with standard cytochemical biomarkers and polarized light microscopy for microplastic tracking in tissue.

Optimisation of enzymatic digestion and validation of specimen preservation methods for the analysis of ingested microplastics

Enzymatic digestion using trypsin provides a suitable, time and cost effective method to extract microplastics from M. edulis, serving to highlight the suitability of biological samples preserved either way for future inquiries into ingested microplastic research.
