Bioaccumulation of polystyrene nanoplastics and their effect on the toxicity of Au ions in zebrafish embryos

Researchers studied the bioaccumulation of polystyrene nanoplastics in zebrafish embryos and their interaction with gold ions. They found that smaller nanoplastics readily penetrated the embryo's protective membrane and accumulated in lipid-rich regions, particularly the yolk. While nanoplastics alone caused only marginal toxic effects, their presence synergistically amplified the toxicity of gold ions through increased oxidative stress and inflammatory responses, suggesting that nanoplastics may worsen the harmful effects of co-occurring environmental contaminants.
