Abstract A simulated one-dimensional column system was established with seawater and natural sea sand to investigate the cotransport of 1μm polystyrene microplastics (PS) and fullerene (C60) in seawater-saturated marine media. The results showed that, in single suspension, the mass percentage recovered from the effluent (Meff) and maximum effluent concentration (MEC) of the well-dispersed PS (15mg/L) were 36.8%, and 0.42, respectively, while the aggregation (agglomeration) of C60 at 15mg/L was obviously presented with 16.8% of Meff and 0.22 of MEC, respectively. When 15mg/L PS and 15mg/L C60 were coexisted, PS might form stable co-aggregates with part of C60 thereby promote the transport of C60. Conversely, C60 inhibited the transport of PS. If the concentration of PS in binary suspension increased from 15mg/L to 45mg/L, the enhancing effect of PS on transport of C60 was eventually transformed into the inhibition of C60 transport, which was mainly due to the increase in the volume and number of PS-C60 co-aggregates.
