Summary

Researchers explored how humic acid, a natural organic substance found in water, interacts with nanoplastics to either reduce or amplify their toxicity to freshwater microalgae. The study found that humic acid can mitigate nanoplastic toxicity by reducing surface hydrophobicity and improving particle dispersion, but this protective effect diminishes at low humic acid concentrations.

Study Type Environmental

Humic acid can mitigate the toxicity of nanoplastics to microalgae by weakening their interactions through lowered surface hydrophobicity and enhanced dispersion stability, but this protective effect is reduced at low humic acid concentrations.
