Neuronal damage induced by nanopolystyrene particles in nematodeCaenorhabditis elegans
AI summary Read the abstract
C. elegans nematodes were chronically exposed to nanopolystyrene particles and found to develop neuronal damage affecting both development and function of the nervous system after long-term exposure at environmentally relevant concentrations. The study provides early evidence that nanoplastics can cause neurological harm in an animal model, raising questions about potential neurotoxicity in other species.
Our observations highlight the potential of nanoplastics in inducing damage on both development and functions of nervous system after long-term exposure.

Polystyrene (nano)microplastics cause size-dependent neurotoxicity, oxidative damage and other adverse effects inCaenorhabditis elegans
AI summary Read the abstract
Researchers found that polystyrene micro- and nanoplastics cause neurotoxicity and oxidative damage in the model organism C. elegans, with effects varying by particle size. Smaller nanoscale particles tended to cause more severe toxic responses than larger microplastic particles. The study highlights that the size of plastic particles is an important factor in determining how harmful they are to living organisms.
Effect of chronic exposure to nanopolystyrene on nematode Caenorhabditis elegans
AI summary Read the abstract
Researchers chronically exposed C. elegans nematodes to nanopolystyrene across their adult lifespan and found that even low concentrations (≥1 µg/L) impaired locomotion and promoted oxidative stress, while also suppressing immune response genes, antioxidant defenses, and mitochondrial stress response pathways, with high concentrations shortening lifespan.

AI summary Read the abstract
C. elegans exposed to 25, 50, and 100 nm polystyrene nanoplastics showed size-dependent neurodevelopmental toxicity — including reactive oxygen species generation, mitochondrial damage, and inhibited dopamine production — with smaller particles (25 nm) paradoxically showing weaker effects than the 50 nm size.
