Abstract
Microplastic (MP) pollution poses increasing environmental and food safety risks, yet the role of hydrodynamics in MPs bioaccumulation and fish physiology is unclear. This study assessed the effects of 5 μm polystyrene MPs (1000 μg/L) on Ctenopharyngodon idella under static conditions and at water velocities of 1, 3, and 5 body lengths per second (BL/s). Fish exposed to high velocity showed highest MPs bioaccumulation (58.1 ± 10.5 × 10 3 μg/kg), and histological damage, including fiber degeneration, necrosis, and hemorrhage. Biomarkers indicated oxidative stress, neurotoxicity, and disrupted energy metabolism, while endocrine and neurochemical disturbances reflected systemic stress and reduced tissue quality.…
