ABSTRACT

Drinking water used during pregnancy was sampled (acidified) in a parallel water arsenic screening project (Rahman et al., 2006) and matched to the cohort of pregnant women (Vahter et al., 2006). We subsequently collected water samples when the children were 5 and 10 years of age (n = 1,017) (Rahman et al., 2015). We measured arsenic and other elements in the water using ICP-MS (Agilent 7700x; Agilent Technologies, Tokyo) (Kippler et al., 2016). Elevated manganese concentrations were found in the deep wells (Ljung et al., 2009), the main mitigation alternative. Thus, we also focused on this metal, the excess exposure of which may cause neurotoxicity.
