If you are breastfeeding it is important to review chemicals, you may be exposed to as some chemicals can enter breastmilk and eventually expose the baby.
Here are examples of a few chemicals that can get into breast milk:
Lead, mercury, and other heavy metals
Organic solvents and volatile organic chemicals (such as dioxane, perchloroethylene, and bromochloroethane)
Chemicals from smoke, fires, or tobacco
Some radioactive chemicals used in hospitals for radiation therapy (such as Iodine-131)
If you work with any of these chemicals, it is important to talk to your doctor about breastfeeding.
