aSample sizes: dams at weaning = 7–11 per group; extra pups = 4–9 per group; final male = 8–17 per group; final female = 8–12 per group. PbBs were not measured during pregnancy or lactation to preclude additional stress from confounding experimental interpretations.

bPbB (F(1,35) = 135.07, p < 0.001).

cPbB (F(1,39) = 326.79, p < 0.001); gender (F(1,39) = 7.29, p = 0.010); Pb × gender (F(1,39) = 4.35, p = 0.044) collected from 2- to 3-month-old pups.

dPb × gender (F(1,157) = 23.04, p < 0.001); Pb × BE (F(1,157) = 17.27, p < 0.001) collected at the completion of the experiment.
