Summary

Adsorption of three antibiotics - ciprofloxacin, sulfamethoxazole, and tetracycline - onto disposable face mask microplastics and nanoplastics was investigated, finding the order SMX > CIP > TC. The adsorption pattern correlated with the octanol-water partition coefficients of the antibiotics, clarifying mechanisms by which mask-derived plastics can accumulate and transport pharmaceutical contaminants.

The adsorption of ciprofloxacin (CIP), sulfamethoxazole (SMX) and tetracycline (TC) on disposable face mask (nano-)microplastics occurs in the order SMX > CIP > TC, which correlates with the octanol–water partition coefficient of antibiotics.
