Exposure to moderate levels of lead during childhood can permanently

from a large brain imaging study. The adults who had higher average

blood lead levels as children also had lower levels of several key

chemicals that are produced in different brain regions. This is the

first large brain imaging study in young adults followed since birth and

adds new insights to the mechanism of lead exposure on brain function....
