FACTs About Low Lead Level Exposures

New studies and re-interpretation of past studies demonstrates that it is not possible to determine a threshold below which BLL is not inversely related to IQ. [2]

Elevated BLLs are associated with Attention Deficit Hyperactivity Disorder (ADHD) and antisocial behavior, which in turn increase the likelihood of conduct disorder.
