Table 1 Maternal and birth outcomes for C57BL/6J dams exposed to 0 (control), 10 or 100μg/L arsenic via drinking water (mean ± SD)

From: In utero exposure to low dose arsenic via drinking water impairs early life lung mechanics in mice

  Control 10μg/L As 100μg/L As
Maternal water consumption (mL/day) 5.11 ± 1.41 4.97 ± 1.36 4.91 ± 1.33
Gestation period (days) 20.1 ± 0.92 20.4 ± 0.88 20.0 ± 0.81
Litter size (pups/dam) 5.63 ± 1.98 4.79 ± 1.87 5.54 ± 2.23
Birth weight (g) 1.34 ± 0.16 1.35 ± 0.19 1.27 ± 0.18 *
Birth length (mm) 29.1 ± 1.74 28.8 ± 1.94 28.4 ± 1.90 *
  1. There were no differences in maternal water consumption, gestation period or litter size between control and arsenic exposed mice. Offspring exposed to 100μg/L arsenic were born significantly smaller than control mice in both weight and length (* indicates significantly different to controls).
