AB  - The role of microplastic (MP) as a carrier of persistent organic pollutants 
      (POPs) to aquatic organisms has been a topic of debate. However, the reverse POP 
      transport can occur if relative contaminant concentrations are higher in the 
      organism than in the microplastic. We evaluated the effect of microplastic on the 
      PCB removal in planktonic animals by exposing the cladoceran Daphnia magna with a 
      high body burden of polychlorinated biphenyls (PCB 18, 40, 128 and 209) to a 
      mixture of microplastic and algae; daphnids exposed to only algae served as the 
      control. As the endpoints, we used PCB body burden, growth, fecundity and 
      elemental composition (%C and %N) of the daphnids. In the daphnids fed with 
      microplastic, PCB 209 was removed more efficiently, while there was no difference 
      for any other congeners and SigmaPCBs between the microplastic-exposed and control 
      animals. Also, higher size-specific egg production in the animals carrying PCB 
      and receiving food mixed with microplastics was observed. However, the effects of 
      the microplastic exposure on fecundity were of low biological significance, 
      because the PCB body burden and the microplastic exposure concentrations were 
      greatly exceeding environmentally relevant concentrations.
