Summary
Daphnia magna exposed to low environmental concentrations of polystyrene nanoplastics (as low as 3.2 micrograms per liter) showed significant metabolic disruptions detectable by metabolomics analysis. Carboxylate-functionalized particles caused distinct metabolic responses compared to amine-functionalized particles, suggesting surface chemistry drives differential toxicity.
Particles used in the study: 53 nm PS-NH 2 and 62 nm PS-COOH. Significant metabolic responses at: 3.2 μg L −1 PS NPs.
