Malformations (e.g., pericardial edema, tissue ulceration, and body arcuation) induced by nFe₂O₃ at 168 hpf.

<p>(A) Malformation percentage in the surviving fish; (B) control fish; (C) hatching fish with body arcuation, treated with 50 mg/L of nFe₂O₃ aggregates; (D) unhatching embryos, treated with 50 mg/L of nFe₂O₃ aggregates, dead at 168 hpf; (E) hatching fish with pericardial edema, treated with 100 mg/L of nFe₂O₃ aggregates. Error bars represent ± one standard deviation from the mean of three replicates. Significance indicated by: *<i>p</i><0.05.
