Figure 1

Toxicants induce similar morphological changes in 120 hpf zebrafish embryos. Embryos were treated with (a) methylmercury chloride (60 μg/l, MeHg); (b) CdCl2 (5 mg/l, Cd); (c) PbCl2 (2.8 mg/l, Pb); (d) As2O3 (79 mg/l, As); (e) Aroclor 1254 (33 mg/l, PCB); (f) acrylamide (71 mg/l, AA); (g) tert-butylhydroquinone (1.7 mg/l, tBHQ); (h) 4-chloroaniline (50 mg/l, 4CA); (i) 1,1-bis-(4-chlorophenyl)2,2,2-trichloroethane (15 mg/l, DDT); (j) 2,3,7,8-tetrachlorodibenzo-p-dioxin (500 ng/l, TCDD); (k) valproic acid (50 mg/l, VA); (l) vehicle 1 control (VC1): embryo water alone (for Cd, MeHg, Pb, As, VA, AA treatments); (m) vehicle 2 control (VC2): 0.2% ethanol control (for 4CA, DDT, tBHQ, PCB); (n) vehicle 3 control (VC3): 0.025% DMSO, 1.4 mg/l toluene (for TCDD). Embryos showed frequently a bent body axis and developed pericardial edema upon further cultivation.
