ClearExposure to polystyrene nanoplastics induces apoptosis, autophagy, histopathological damage, and intestinal microbiota dysbiosis of the Pacific whiteleg shrimp (Litopenaeus vannamei)
Exposing Pacific white shrimp to nanoplastics caused intestinal damage, cell death, disrupted immune function, and increased the abundance of harmful gut bacteria. Higher concentrations of nanoplastics led to more severe effects, including visible damage to the intestinal lining and formation of autophagosomes (cellular waste structures). These findings add to growing evidence that nanoplastic contamination in seafood farming can compromise the health of organisms that many people eat.

The study adds to growing evidence that nanoplastics can harm the health of commercially important marine species.
Polystyrene nanoplastics induce lipid metabolism disorder and alter fatty acid composition in the hepatopancreas of Pacific whiteleg shrimp (Litopenaeus vannamei)
Researchers exposed Pacific whiteleg shrimp to different concentrations of polystyrene nanoplastics for 28 days and found significant disruption to fat metabolism in the shrimp's digestive organ. Higher concentrations caused tissue damage, reduced protein and fat content, and altered the activity of enzymes that control how the body processes fats. Since shrimp is a widely consumed seafood, these findings raise questions about how nanoplastic contamination in aquaculture could affect the nutritional quality and safety of shellfish for human consumption.

Effects of nanoplastics on the gut microbiota of Pacific white shrimp Litopenaeus vannamei
Researchers fed polystyrene nanoplastics to Pacific white shrimp and found significant damage to their gut bacteria, intestinal structure, and immune system. The nanoplastics increased harmful bacteria like Vibrio while reducing beneficial species, and visibly damaged the intestinal lining. Since shrimp are widely consumed seafood, these gut health disruptions raise questions about how nanoplastic contamination in farmed and wild shrimp could affect both the animals and the people who eat them.
Multi-omics reveals the particle size effect of nanoplastics on the hepatopancreas and intestinal toxicity of crustacean model Neospoda palmata
Researchers used multi-omics techniques to study how polystyrene nanoplastics of different sizes affect freshwater shrimp over 35 days of exposure. They found that smaller nanoplastics (75 nm) were more likely to trigger cell death than larger ones (200 nm), and both sizes caused significant organ damage, gene expression changes, and disruption of gut bacteria. The study reveals that particle size plays a critical role in determining the toxicity of nanoplastics to aquatic organisms.

Exposing common carp to polystyrene nanoplastics caused significant DNA damage in blood and brain cells, along with changes in genes related to immune function and stress response. Higher concentrations led to more severe effects, and the nanoplastics also disrupted liver antioxidant defenses. Since carp are widely consumed fish, these findings raise questions about the safety of fish from nanoplastic-contaminated waters for human consumption.
Size-dependent toxicological effects of polystyrene microplastics in the shrimp Litopenaeus vannamei using a histomorphology, microbiome, and metabolic approach
Researchers exposed white leg shrimp to polystyrene microplastics of four different sizes and found that toxicity was strongly size-dependent, with smaller particles causing greater tissue damage to guts and gills. Smaller microplastics were also more readily ingested and bioavailable to the shrimp. However, larger particles triggered different responses in gut microbiome diversity and metabolic pathways, indicating that microplastic size influences the type and severity of biological effects.
