Extended Data Fig. 1: The quantitative results on the generation of nanoplastics from different microplastics by rotifers.

(A): The numbers of nanoplastics generated from PS fibers; (B): The numbers of nanoplastics generated from PS microplastics obtained from the food container. Data are presented as mean ± s.d. (n = 3 for all groups in Panel A and “PS debris in rotifers” group in Panel B; n = 4 for “original PS debris” group and “PS debris in medium” group in Panel B). Statistical analyses were performed using a one-sided ANOVA followed by LSD post hoc test.
