Exposure to lead can be harmful to the unborn baby because lead in the mother’s blood passes through the placenta. Complications from high levels of exposure include premature birth, low birth weight, or even miscarriage or stillbirth.
Breastfeeding mothers can also pass lead on to their infants via their breast milk.
The effects of lead exposure continue after birth and can result in impaired learning and mental ability.
