Each temperature degree counts: warming enhances nanoplastic toxicity via metabolic disruption in a marine cellular model

Each temperature degree counts: warming enhances polystyrene nanoplastic toxicity via metabolic disruption in a marine cellular model

AI summary · Read the abstract

This study examined how elevated water temperatures — simulating marine heatwaves — amplify the toxicity of polystyrene nanoplastics in marine cells, finding that warming enhanced metabolic disruption caused by nanoplastics. The results suggest climate change and plastic pollution interact synergistically to harm marine organisms.

Molecular mechanisms of microplastics toxicity

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.

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.

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.
