Bone Lead and Cognitive Function

Workers exposed to lead show more cognitive problems later in life. This article is vital to understand. Bone lead has a 1/2 life of 30 years, and it is in equilibrium with other tissues, leading to cataracts, as published in JAMA by Harvard and now this vital study ties it to loss of cognitive function!

"2004, the current study followed up with 83 of the original lead-exposed workers and 51 of the original non-exposed workers. Researchers measured current lead levels in their blood and cumulative lead levels through special X-rays of the tibia, or lower leg bone (bone is the final repository of circulating blood lead, where it has a half life of about 30 years). Researchers also re-administered the test battery to assess cognitive performance relative to both measures of lead. Read more..
