Heavy metal in pregnancy: Health risks
Date: Aug 15, 2012
Author: David Bradley
Atomic absorption spectroscopy has been used to measure levels of metals in blood plasma from expectant mothers as a proxy for oxidative stress. Increased levels of iron in pregnancy reveals an association with high blood pressure conditions including hypertension and pre-eclampsia, although causation is not demonstrated.
