Babies are vulnerable to chemical harm

Parents know intuitively that babies in the womb are more vulnerable to the effects of industrial chemicals than adults. A pregnant woman may avoid using hair dye and nail polish, pumping gas, or painting the nursery, for example, to protect her baby. This intuition is backed by science that has unfolded primarily over the past two decades. In 1993 the National Academy of Sciences enumerated, in a Congressionally mandated study, the primary factors that contribute to children's unique vulnerability to the harmful effects of chemicals (NAS 1993):

• A developing child's chemical exposures are greater pound-for-pound than those of adults.
• An immature, porous blood-brain barrier allows greater chemical exposures to the developing brain.
• Children have lower levels of some chemical-binding proteins, allowing more of a chemical to reach "target organs."
• A baby's organs and systems are rapidly developing, and thus are often more vulnerable to damage from chemical exposure.
• Systems that detoxify and excrete industrial chemicals are not fully developed.
• The longer future life span of a child compared to an adult allows more time for adverse effects to arise.

The pace and complexity of growth and development in the womb are unmatched later in life. Three weeks after conception, an embryo, still only 1/100th the size of a water droplet, has nevertheless grown at such an explosive rate that were it not to slow down, it would be born literally the size of a million Earths. Over the next five weeks the baby constructs the beginnings of elbows, knees, eyelids, nipples, hair follicles on chin and upper lip, external genitals, primitive internal organs, a four-chambered heart, working fingers and toes, and even a footprint (Greene 2004). At no other time in life does a person create so much from so little in so short a time. Industrial chemicals that interrupt this intricate process can, at high levels, wreak havoc in the form of severe birth defects, or at lower levels cause subtle but important changes in development that surface later in childhood as learning or behavioral problems, or in adulthood in the form of certain cancers or perhaps neurodegenerative disease.
