Size-dependent effects of polystyrene Nanoplastics on hepatic Immunometabolism and the gut-liver Axis in the Swamp Eel (Monopterus albus)

Gauging the effects of a chronic exposure to polystyrene nanoplastics in the liver and intestine of Carassius auratus

Polystyrene nanospheres-induced hepatotoxicity in swamp eel (Monopterus albus): From biochemical, pathological and transcriptomic perspectives

AI summary · Read the abstract

Researchers exposed swamp eels to polystyrene nanoplastics for 28 days and found significant liver damage including oxidative stress, tissue abnormalities, and disrupted gene expression related to immune response and metabolism. Higher concentrations caused more severe liver injury, with changes detectable at both the biochemical and genetic levels. This study adds evidence that nanoplastic exposure can harm liver function in freshwater species important to aquaculture and local food supplies.

Physiological Alterations and Immune Modulation in Fish Exposed to Microplastics
