Impact of Micro-nanoplastics on Gut and Immune Function

AI summary Read the abstract

This review examined how micro- and nanoplastics disrupt gut microbiota and immune function across aquatic and terrestrial vertebrates, with implications for human health. Because the gut microbiome governs immune regulation and metabolic health, microplastic-induced dysbiosis represents a plausible mechanism by which plastic ingestion could drive systemic inflammation and disease beyond the GI tract.

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.

Effects of Nanoplastics on the Living Environment

AI summary Read the abstract

Researchers reviewed the many ways nanoplastics — plastic fragments too small to see without a microscope — affect living organisms and broader ecosystems, finding evidence of harm to reproduction, behavior, and cellular function across multiple species. Because nanoplastics are even harder to detect and filter than microplastics, they may pose an underappreciated threat to biodiversity and food chains.

Long‑term exposure of polyethylene nanoplastics promotes colorectal tumorigenesis

AI summary Read the abstract

Researchers exposed mice to polyethylene nanoplastics over 66 days and found significantly more colon tumors and heavier tumor burdens compared to controls, with nanoplastics alone triggering colorectal polyps, suggesting these particles promote tumor initiation by disrupting mitochondrial structure and amplifying chronic intestinal inflammation.

Micro-nano Plastics: Impact on Gastrointestinal System

AI summary Read the abstract

Researchers reviewed how micro- and nanoplastics affect the gastrointestinal system, finding that ingested plastic particles can disrupt gut lining integrity, alter the gut microbiome, trigger inflammation, and may contribute to digestive disorders — raising concern given that humans ingest microplastics daily through food, water, and air.
