Is it true that lead doesn't cross placenta until 12 weeks?
A doctor has provided 1 answer
Probably harmful: Exposure to lead is probably harmful to the formation of the placental cells as well as the developing embryo and fetus. Since lead is a heavy metal, it may remain in placental, embryonic and fetal tissues for months to years and cause permanent and often irreversible damages.
