According to a new study by researchers at Dartmouth College in Hanover, New Hampshire, the placenta can be used to measure arsenic exposure in pregnant moms and how much the toxic metal is transferred to their fetuses.
The danger of arsenic exposure has been a hot topic in recent years.
The research appears in the Journal of Exposure Science and Environmental Epidemiology and is the largest study to ever anayze the arsenic in household drinking water and the resulting mother-to-fetus connection.
From a press release:
"Our findings show placental arsenic concentrations reflect both maternal and fetal biomarker concentrations," says lead author Tracy Punshon, a research assistant professor of biological sciences. "They support placenta as a potentially useful biomarker of arsenic exposure, particularly in studies of placental function. They suggest greater maternal-fetal transfer when placental arsenic is high."
