Mean ± SEM forelimb grip strength force in newtons (N) at six postnatal ages for male offspring (top panel) and female offspring (bottom panel). The puberty age measurements were collected on the day of puberty onset for each juvenile animal. Puberty ages were then averaged to generate the X-axis coordinate. Sample size: 0 ppm n = 7 litters, 8 ppm n = 10, 25 ppm n = 6, 80 ppm n = 6.
