We quantify plastic litter (PL, 2 cm) and microplastics (MP, less then 5 mm) from the sediments of a beach formed at a riverine depositional area, at the upper Amazon River basin, Ecuador. In the collection area (4400 m2), the PL density was 0.045 items m-2, where low-density polyethylene bags were the prevalent PL. The beach was classified as "very clean" (Clean Coast Index (CCI) of 1.3 items m-2). Regarding MP, in 55 sampling stations, average MP concentrations ranged from 0 to 2200 items kg-1 of dry sediment (0.5-2 mm), and
