Effects of polystyrene nanoplastics on apoptosis, digestive enzymes, and intestinal histological structure and flora of swamp eel (Monopterus albus)
Summary
Researchers exposed swamp eels (Monopterus albus) to polystyrene nanoplastics and found inflammation in the liver and intestine, significant gene expression changes in the liver, and shifts in intestinal microbial community composition toward more pathogenic taxa. The results demonstrate that nanoplastic exposure disrupts apoptosis pathways, digestive enzyme activity, and gut microbiome health in this freshwater fish.
After the swamp eel ( Monopterus albus ) was exposed to NPs, it showed inflammation in the liver and intestine, significant changes to genes in the liver, and an increase in the abundance of pathogenic bacterial populations in the intestine.

Polystyrene nanospheres-induced hepatotoxicity in swamp eel (Monopterus albus): From biochemical, pathological and transcriptomic perspectives
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.
Dietary polystyrene nanoplastics exposure alters hepatic glycolipid metabolism, triggering inflammatory responses and apoptosis in Monopterus albus
Researchers fed swamp eels different concentrations of polystyrene nanoplastics and found dose-dependent liver damage, including disrupted fat and sugar metabolism, inflammation, and cell death. Higher nanoplastic doses caused more severe oxidative stress and activated harmful signaling pathways in liver tissue. The study adds to growing evidence that nanoplastic ingestion can significantly impair liver function in aquatic species.
Effect of polystyrene nanoplastics on the intestinal histopathology, oxidative stress, and microbiota of Acrossocheilus yunnanensis
Researchers studied the effects of polystyrene nanoplastics on the intestinal health of a freshwater fish species and found significant damage to the gut lining, including ruptured tissue and damaged nutrient-absorbing structures. The nanoplastics also increased oxidative stress markers and shifted the composition of gut bacteria, reducing beneficial species. The findings suggest that nanoplastic exposure can compromise both the physical barrier and microbial balance of fish intestines.
Effects of polystyrene nanoplastic exposure on energy metabolism, lipid metabolism, and amino acid changes in Monopterus albus
Researchers exposed Asian swamp eels to different concentrations of polystyrene nanoplastics over 35 days to study effects on metabolism. Evidence indicates that high concentrations of nanoplastics disrupted energy metabolism by altering gluconeogenic pathways and affected amino acid profiles, suggesting that nanoplastic ingestion through the food chain may pose metabolic risks to aquatic organisms.
Interactions between intestinal microbiota and metabolites in zebrafish larvae exposed to polystyrene nanoplastics: Implications for intestinal health and glycolipid metabolism
Zebrafish larvae exposed to polystyrene nanoplastics suffered intestinal damage, including inflammation, oxidative stress, and disrupted gut bacteria -- with increases in bacteria linked to gut disease. The nanoplastics also altered metabolism related to sugar and fat processing, suggesting that ingesting these tiny particles could harm digestive health and disrupt how the body processes nutrients.
