PCA (A) and PLS-DA (B) plots representing the metabolite profiling of zebrafish embryos at 4, 24, 48, 72, and 120 hpf.

The relative response of metabolites representative of various classes in zebrafish embryos at different developmental stages: 4 hpf (darkgrey), 24 hpf (orange), 48 hpf (darkblue), 72 hpf (red), and 120 hpf (black). All of the shown metabolites are significant compared to 4 hpf, for more details about significant differences between groups see Supplementary Materials.

In zebrafish at 120 hpf, (A): Example of significantly affected metabolites by exposure to PFHxS at 0.3 μM (green), 1 μM (purple), 3 μM (blue), and 10 μM (pink), compared to the controls (red). (B): The four most affected metabolic pathways by 3 μM PFHxS. Other significantly affects metabolites can be found in Supplemental Materials.

An overview of the dysregulated metabolic pathways by PFHxS and the affected metabolites by 3 μM PFHxS in zebrafish embryos at 120 hpf.
