Toxic Effects of Microplastic (Polyethylene) Exposure: Bioaccumulation, Hematological Parameters, and Antioxidant Responses in Crucian Carp, Carassius Carassius

Polyethylene Microplastics Induce Concentration- and Time-Dependent Hematophysiological Impairment and Oxidative Stress Following Tissue Accumulation in Rock Bream (Oplegnathus Fasciatus)

Toxicity Impact of Polyethylene Microplastics on Biochemical Parameters and Oxidative Stress in Benni Fish (Barbus sharpeyi)

AI summary · Read the abstract

Benni fish exposed to increasing concentrations of polyethylene microplastics showed significant liver enzyme disruption, elevated cholesterol and triglycerides, and clear signs of oxidative damage in their cells. These dose-dependent biochemical changes suggest that microplastic exposure causes systemic physiological stress in fish, raising concerns about the health of species humans consume.

The damaging effects of polyethylene microplastics exposure on juvenile carp and the ameliorative role of Opuntia Milpa alta extract

AI summary · Read the abstract

Researchers exposed juvenile carp to polyethylene microplastics for 45 days, documenting liver damage, inflammation, and gut microbiota disruption, then found that Opuntia cactus extract significantly reduced liver enzyme markers and restored microbial diversity, suggesting natural plant extracts may help counteract microplastic toxicity.

New Insights into the Effects of Polystyrene Microplastics on Freshwater Fish, Labeo rohita: Assessment on Histopathology, Mineral Composition, Bioaccumulation and Antioxidant Activity

AI summary · Read the abstract

Researchers fed Labeo rohita fish diets containing up to 2.5% polystyrene microplastics over 90 days and found dose-dependent intestinal damage, reduced antioxidant enzyme activity, altered mineral composition in muscle tissue, and bioaccumulation of particles, suggesting risks to farmed fish health and potentially to people who consume them.

Toxic effects of microplastic (polyethylene) exposure: Bioaccumulation, hematological parameters and antioxidant responses in crucian carp, Carassius carassius

AI summary · Read the abstract

Researchers exposed crucian carp to polyethylene microplastics at various concentrations and found that the particles accumulated in tissues including gills, gut, and liver. The microplastics altered blood cell counts and disrupted the fish's antioxidant defense system in a dose-dependent manner. The study suggests that even common polyethylene microplastics can cause measurable biological harm in freshwater fish.
