Size-Dependent Tissue Translocation and Physiological Responses to Dietary Polystyrene Microplastics in Salmo trutta.

ABSTRACT: Microplastics (MPs) are prevalent in freshwater systems; consequently, fish ingest them either accidentally or intentionally. Once ingested, MPs can translocate to various organs and cause physiological effects. Most studies have focused on tropical and marine fishes, and many have used mass-based methods that measure exposure only by the total mass of microplastics, ignoring particle number and size. These studies have also rarely examined MP effects or fate after a depuration period, limiting our understanding of MP impacts on temperate fishes, hindering the harmonisation of toxicological studies, and complicating assessments of food safety for cultured and wild fish. This study investigated the physiological impacts of dietary exposure to polystyrene microplastics (PS-MPs; 1-10 µm) in <
