Small microplastics on beaches of Fernando de Noronha Island, Tropical Atlantic Ocean

A study on the beaches of Fernando de Noronha Island, part of the UNESCO World Heritage Sites, reveals that small microplastics (SMP) are prevalent, with synthetic fibers being the predominant type. The research analyzed SMP from 15 sandy beaches, categorizing them by shape, color, and size. No significant difference was found in the concentration of SMP between windward and leeward beaches, indicating that environmental factors controlling the transport and deposition of synthetic fibers may differ from those affecting fragments. While allochthonous sources are challenging to prevent at a small scale, the study underscores the necessity for management actions to curb autochthonous sources of microplastics on the island.
