Selectivity of larger particles of microplastics occur along the shoreline in coastal areas where debris becomes beached. UV radiation and temperature encourage fragmentation of particles before being reintroduced and resuspended into the marine environment either by wind or wave motion, which is then transported towards offshore areas or may sediment along closer to the shore . Larger particles, sheet type and denser polymers (PET, PVC, PMA, PAA) and other plastics (nylon, polyamide etc.) were found in higher concentration in the sediment compared to the surface water, suggesting a selective sinking of these particles. Overall, our data suggest that rapid selective sinking of microplastics occurs in the coastal areas, before they reach offshore waters.
