Some basic facts about chemical exposure and children:

Our children are growing up in a different world.
While some environmental hazards have decreased in the last ten years, our children are now coming into contact with thousands of new and virtually untested chemicals every day in their food, water and air. These chemical exposures have actually changed the face of childhood illness and disease.

Per pound of body weight, your child actually drinks more, breathes more and eats more than you do.
That means that children will have a substantially higher exposure level than adults. For example when a child eats a banana that contains the legally allowed level of pesticides they actually take in more pesticide per pound of body weight than an adult, actually pushing their exposure level above what's been deemed “acceptable.” The same is true of indoor air. A resting newborn breathes in twice as much air as an adult, resulting in a greater exposure to airborne chemicals.

Normal kid behavior, exposes them to more chemicals
There are two basic facts about kids; everything goes into their mouth and their favorite place to be is crawling, walking or playing on the floor. These two basics of childhood increase their ingestion of toxins on the floor, in carpets, in dust. In addition, airborne toxins tend to stay in the air that's close to the floor.

Your child's developing body doesn't work like yours does.
A child's metabolism is immature and can't always excrete chemicals as efficiently as an adult, consequentially, they are more vulnerable to their effects.

A baby exposed to toxins early in life, will have years in which his/her body can be affected.
Many researchers now believe that disease is an on-going process in the body that may take years to evolve from the earliest stage. Therefore a child exposed to a cancer-causing toxin early-on will have an increased chance of developing a disease later in life – simply because it will have more time to evolve.
