AB  - It has been hypothesized that persistent organic pollutants (POPs) in 
      microplastic may pose a risk to aquatic organisms. Here we develop and analyze a 
      conceptual model that simulates the effects of plastic on bioaccumulation of 
      POPs. 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"). The model is parametrized for the lugworm 
      Arenicola marina and evaluated against recently published bioaccumulation data 
      for this species from laboratory bioassays with polystyrene microplastic. Further 
      scenarios include polyethylene microplastic, nanosized plastic, and open marine 
      systems. Model analysis shows that plastic with low affinity for POPs such as 
      polystyrene will have a marginal decreasing effect on bioaccumulation, governed 
      by dilution. For stronger sorbents such as polyethylene, the dilution, carrier, 
      and cleaning mechanism are more substantial. In closed laboratory bioassay 
      systems, dilution and cleaning dominate, leading to decreased bioaccumulation. 
      Also in open marine systems a decrease is predicted due to a cleaning mechanism 
      that counteracts biomagnification. However, the differences are considered too 
      small to be relevant from a risk assessment perspective.
