Sediment reworking activity of two marine polychaetes (H. diversicolor; A.marina) representing different bioturbation types resulted in considerable differences in microplastic transport. Size-selective feeding activity of A. marina caused a long-term retention of larger microplastic particles in considerable sediment depths down to 20 cm, emphasizing the ability of certain bioturbation types to facilitate deep or fast particle transport.
