The overwhelming tone highlights the issue as a significant health crisis with lasting societal effects, suggesting a high degree of importance.

Abstract in brief

  • Over 170 million Americans were exposed to harmful lead levels during childhood, often at significantly higher levels than today's safety standards.
  • Past lead exposure, referred to as "legacy lead exposure," continues to impact public health, particularly for those affected individuals.
  • Lead exposure is linked to substantial IQ loss, with estimates showing that it contributed to the loss of approximately 824 million IQ points in the U.S. by 2015.

Gen X, NOT 'Boomers', are the generation with the highest lead levels in childhood & the highest IQ loss as a result. On average, someone born between 1966 and 1970 lost 5.9 IQ points due to lead exposure, 1970-1975, 5.1 points. Half of children tested in 1976 were 4X the CDC's 'action threshold'.

@Cyndy9903794356 @garonnevik @GudimJason It's unfortunately true. People who grew up in that time period were consistently exposed to high concentrations of lead in the environment & it was detectable in their blood. Lead is known to cause brain damage & the symptoms match a stereotypical boomer https://t.co/n4F3CrDE5A

Gen X, NOT 'Boomers', are the generation with the highest lead levels in childhood & the highest IQ loss as a result. On average, someone born between 1966 and 1970 lost 5.9 IQ points due to lead exposure, 1970-1975, 5.1 points. Half of children tested in 1976 were 4X the CDC's 'action threshold'.
