摘要: Abstract The objective was to establish possible temporal patterns in the microplastics (MPs) abundance water and intertidal sediment an urbanized location of Rio de la Plata estuary (Argentina), relation environmental factors. site sampled monthly for a year (February 2019–January 2020). presence MPs recorded, being more abundant February (110 m−3) April (613 m−2). types found were fibers, fragments, pellets, film foam; while polymers identified polyethylene (PE) polypropylene (PP). Regarding variables, predominance wind from NE direction related greater accumulation sediment, NO associated with lower water. Also, negatively larger sizes particles.
