Although a few initial measures implemented about 30 years ago were effective in somewhat reducing levels of lead exposure in children, relatively little has been done recently from a policy perspective to protect children from lead.

TWO SERIES OF STUDIES WHOSE SUBJECTS WERE EITHER HOODED AND ALBINO RATS OR YOUNG CHILDREN INVESTIGATED THE INFLUENCE OF EARLY EXPERIENCES ON LATER BEHAVIOR. IN THE FIRST, BOTH SUBSPECIES OF RATS WERE EXPOSED TO EITHER ENRICHED OR RESTRICTED ENVIRONMENTS TO ASSESS THEIR PROBLEM-SOLVING ABILITIES UNDER VARIOUS LEARNING CONDITIONS. THE RESULTS…

Developmental models currently used by child behavioral toxicologists and teratologists are inadequate to address current issues in these fields. Both child behavioral teratology and toxicology scientifically study the impact of exposure to toxic agents on behavior development: teratology focuses on prenatal exposure and postnatal behavior…

Addresses nutritional problems associated with developmental problems in infancy and childhood.

Treatment for undernutrition does not appear to reverse all negative effects. Prevention of nutritional disorders is better…
