‘An Assault on Children’s Brains’: Toxic Chemicals to Blame for Decline in Kids’ IQs

Barbara Demeneix, R. Thomas Zoeller

Brain function, especially in children, is often evaluated by intelligence tests resulting in an Intelligence Quotient or “IQ.”

IQ scores, after having increased for most of the 20th century, have been going down since the mid- 1990s.

… Is this trend for real?

Some technical issues related to IQ measurements may be playing a role. However, scientific studies show that chemical exposures harm brain function in our children.

… Many of these chemicals affect brain development, especially endocrine-disrupting chemicals. Reducing exposure to these mixtures of chemicals offers the single best approach to improving the mental and physical health of our children.
