Determinants of arsenic methylation efficiency and urinary arsenic level in pregnant women in Bangladesh

Prenatal inorganic arsenic (iAs) exposure is associated with pregnancy outcomes. Maternal capabilities of arsenic biotransformation and elimination may influence the susceptibility of arsenic toxicity. Therefore, we examined the determinants of arsenic metabolism of pregnant women in Bangladesh who are exposed to high levels of arsenic.In a prospective birth cohort, we followed 1613 pregnant women in Bangladesh and collected urine samples at two...
