Introducing the ACSH Science Dispatch Podcast — the weekly show where we separate science fact from science fiction.
blood lead levels
I became most interested in the two reports on lead we ran in Dispatch last week. I had looked at this topic a few years ago, and at the time I was concerned that ACSH had on its website some older commentaries that seemed to downplay the danger of lower blood levels. Now, let me share some of my thoughts.
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.
