Why do environmental hazards place infants brains more at risk than adults brains?

Due to their size, physiology, and behavior, children are more vulnerable than adults to environmental hazards. Children are more heavily exposed to toxins in proportion to their body weight, and have more years of life ahead of them in which they may suffer long-term effects from early exposure.

Why children can be more exposed to environmental agents than adults?
