Toxic Effects on Accumulation, Hematological Parameters and Antioxidant Responses in Korean Bullhead, Pseudobagrus Fulvidraco by Exposure to Microplastic (Polyamide)

Toxic effects of microplastic (Polyethylene) on fish: Accumulation, hematological parameters and antioxidant responses in Korean Bullhead, Pseudobagrus fulvidraco

Korean bullhead fish exposed to polyethylene microplastics for just 96 hours showed significant toxic effects including microplastic buildup in the gut, gills, and liver. The fish developed blood abnormalities, liver stress, and disrupted antioxidant defenses, with effects worsening at higher concentrations. Since this species is a common freshwater fish, these findings raise concerns about microplastics affecting the health and safety of fish that people eat.
