Summary
Researchers found that exposing intestinal cells (Caco-2) to polystyrene nanoplastics impaired DNA repair mechanisms even at doses that didn't kill the cells, raising concern that nanoplastic exposure could lead to genetic instability and long-term health risks over time.
Polymers
This study highlights the sublethal effects of nanoplastics on intestinal barrier cells. It underscores the possible risks of exposure to these environmental contaminants, which can lead to genome instability and other long-term health consequences.
