Effects of Polymethacrylate Nanoplastics on Lipid Metabolism in Sparus Aurata
AI summary Read the abstract
Researchers investigated how nanoplastic particles affect fat metabolism in gilthead seabream, an important aquaculture fish, suggesting that even at very small sizes, plastic particles may interfere with key physiological processes in marine species.
Small plastic particles are considered emerging pollutants, and this has motivated research to establish their ecological and environmental consequences. Currently, the study of the effects of nanoplastics (NPs) in aquatic organisms is still scarce, especially in...

Disruption of lipid metabolism under plastic siege: Unraveling the toxic mechanisms of microplastics and nanoplastics
AI summary Read the abstract
Researchers reviewed how microplastics and nanoplastics disrupt lipid metabolism across multiple animal species, finding they inhibit digestive enzymes, alter gut microbiota, dysregulate fat storage and breakdown, and activate inflammatory signaling pathways — causing both acute and chronic metabolic damage.
Cellular and Animal Toxicities of Micro- and Nanoplastics
AI summary Read the abstract
Researchers reviewed evidence from cell and animal studies on the toxic effects of micro- and nanoplastics, finding that these particles can cause inflammation, oxidative stress, and organ damage in laboratory models, raising concern about what chronic low-level human exposure might mean for long-term health.
The Role of Humic Acids on the Effects of Nanoplastics in Fish
AI summary Read the abstract
Humic acids — naturally occurring organic compounds in freshwater — alter the surface properties of nanoplastics and modulate their toxicity to fish, in some cases reducing harm and in others increasing it. This finding shows that environmental context matters when assessing nanoplastic risk, as water chemistry can substantially shift biological outcomes.
Microplastics and nanoplastics in human health: a comprehensive review of exposure pathways, cellular mechanisms, and toxicological implications
AI summary Read the abstract
Researchers reviewed human exposure pathways to microplastics and nanoplastics through seafood, salt, drinking water, inhalation, and skin contact, examining how these particles cross biological barriers to reach organs and trigger oxidative stress, inflammation, and endocrine disruption with poorly understood long-term consequences.
