Summary

Researchers used gold-core polystyrene nanoparticles as a dual-detectable model to quantify nanoplastic toxicity in vivo, finding that chronic exposure induced intestinal accumulation and systemic toxicity, and used these data to extrapolate human health risk thresholds.

Polymers
Study Type In vivo

AuPS-NPs replicate PS-NPs toxicity and enable quantitative risk assessment. Chronic exposure may induce intestinal accumulation and systemic toxicity, underscoring the need for regulatory thresholds to mitigate nanoplastic risks.
