Would really like to hear your theory about how IQ loss causes lead poisoning.

  In well-controlled studies, primarily via developmentally delayed children ingesting more dust/dirt. It's also worth pointing out that actual lead poisoning occurs at levels above about 60 mcg/dL, is very rare nowadays, and that the lead-IQ curve actually regresses toward the mean once you approach that sort of extreme lead level.
