Microplastics (MP) have been recorded in marine ecosystems around the world; however, little is known about the temporal and spatial variation of PM on marine beaches in Peru. In this work, PM were evaluated in Emerita analoga (Crustacea: Hippidae) and in the sediments of eight sandy beaches, north and south of the city of Lima, in two seasons. Thirty individuals of E. analoga and sediment samples were collected from each of the eight beaches for each season (winter and summer). The PM were extracted, counted and characterized. An abundance of 0.02 ± 0.13 to 1.82 ± 6.31 PM items/individual was observed in E. analoga and in the sediments they varied from 41 ± 31.07 to 5353 ± 4013 PM items/kg. Fragments were the predominant type in the sediments, whereas fibres were the predominant type in E. analoga. Transparent was the most frequent color. Particle sizes in the sediment ranged mainly between 1000 and 3000 μm, and in E. analoga less than 1000 μm. It can be affirmed that spatio-temporal variation plays a more important role in the dynamics of PM in sediments compared to E. analoga. The abundance of PM in the beach sediment was not related to the proportion of individuals in E.
