Microplastics are a pervasive pollutant of aquatic ecosystems and are reported to interact with a wide range of aquatic biota. The complexities of natural food webs means that the transfer and accumulation of microplastics is difficult to assess, and only a handful of studies have attempted to quantify trophic transfer in freshwater biota. Bioaccumulation models can provide a valuable tool to explore the transfer of microplastics along complex food webs, but such approaches have been rarely applied to freshwater ecosystems. Here, a food web accumulation model was implemented to assess the transfer, bioaccumulation and hence biomagnification potential of microplastics along a food web located in the River Slaney catchment in south-east Ireland. Literature feeding values and environmental field data were used to simulate microplastic uptake in benthic macroinvertebrates, with fish and Eurasian otter (Lutra lutra (Linnaeus, 1758)) comprising the higher trophic levels. Microplastic concentrations from the model were used to form a basis of comparison with empirical data for benthic macroinvertebrates and brown trout (Salmo trutta Linnaeus, 1758).
