Toxic effects of polystyrene nanoplastics during transport and redistribution in distinct plant species: A combined split-root experiment and metabolomic analysis.

Nanoplastics (NPs) can undergo long-distance transport via the "root-shoot-root" pathway, yet their systemic toxicity during this process remains unclear. Using a split-root system, this study investigated the toxic effects of polystyrene (PS) NPs tr…
