lead and cognition

This article, which complements the one by my colleague Chuck Dinerstein, discusses the broad findings of a provocative study that ties IQ loss directly with childhood lead exposure. The study estimates that 90% of the children born between 1950 and 1980 had clinical concerning blood lead levels, resulting in decreased IQ levels. Certainly, these results will cause great concern among us baby boomers, and some might even say that this finding helps explain many of the world’s problems.
