Morphological features of zebrafish larvae at 120 hpf exposed to low (0.1 mg/L) and high (1 mg/L) concentrations of PLA-NPs and PS-MPs. Three larvae of 120 hpf for each experimental group were used for morphological assessment. A-E) Representative images of H&E staining (A) control; (B) PLA-NPs 0.1 mg/L; (C) PLA-NPs 1 mg/L; (D) PS-MPs 0.1 mg/L; (E) PS-MPs 1 mg/L. Magnification 10X and 40X, scale bar 20 and 100 μm. a-b) Representative detailed images of H&E staining: (a) brain and (b) liver of the related groups (A-E). The vacuolization is indicated by black arrows. Magnification 40X, scale bar 20 μm.
