Developmental A1254 exposure decreases serum thyroid hormone levels. Developmental A1254 exposure caused significant dose- dependent decreases in total serum T₄ and T₃ at P21. This effect persisted in the 6 mg but not the 1 mg/kg/day A1254 treatment group at P31. No sex differences were observed. Data are presented as mean ± SEM (n = 7–9/group).

*p < 0.05 (two-way ANOVA, with treatment and sex as main effects; Fisher’s LSD post hoc).
