    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

Abstract It has been hypothesised that persistent organic pollutants (POPs) in microplastic may pose a risk to aquatic organisms. Here, we present a conceptual model for bioaccumulation of POPs including uptake from water, food and ingested plastic. The model accounts for dilution of exposure concentration by sorption of POPs to plastic (POP 'dilution'), increased bioaccumulation by ingestion of plastic containing POPs ('carrier'), and decreased bioaccumulation by ingestion of clean plastic ('cleaning'). A dynamically modelled absorption efficiency from plastic is proposed, which is calculated from particle size, POP polymer diffusivities, the time variable gradient between plastic and organism POP concentrations, and gut retention time. The model is parameterised for the lugworm Arenicola marina and evaluated against recently published polychlorinated biphenyl (PCB) bioaccumulation data for this species from laboratory bioassays with polystyrene microplastic. Further scenarios include polyethylene
