Overall Experimental Design.

Embryonic zebrafish were developmentally exposed from 6 to 120 hpf (top; hpf = hours post-fertilization). The embryos were exposed to 10 concentrations of PFAS (plate design: all shades of blue), 4 concentrations of PC (parathion ethyl positive control; gray), and vehicle control (white). At 24 and 120 hpf, embryos were assessed for mortality and 10 morphological endpoints and a summary endpoint (ANY). Examples are: CRAN = craniofacial malformations, EDEM = edema, AXIS = bent axis. Embryonic and Larval Photomotor Response are behavior assays in which movement was assessed in response to 2 flashes of light or alternating light/dark cycles at 24 and 120 hpf.
