From: Effects of arsenic exposure on DNA methylation in cord blood samples from newborn babies and in a human lymphoblast cell line

Study locations Arsenic concentration (μg/L)
  Drinking water Non-drinking water
Arsenic-contaminated site 8.38 ± 2.49 a,* 78.05 ± 20.92*
(n =46) 0.86 (0.17-61.63)b 16.54 (1.14-518.69)
Control site 0.18 ± 0.07 0.99 ± 0.04
(n = 18) 0.04 (nd-0.98) 1.10 (nd-1.05)
  1. The values are expressed as the mean ± SE (a) and median (min - max) (b).
  2. nd : non detectable.
  3. * : statistically significant difference from controls at p < 0.05.
