timing of the lead exposure documented in teeth
There is an important, subtle point, not well covered in the article, about the timing of the lead exposure shown by examining deciduous teeth. The lead level in the teeth is related to lead exposure at the time the teeth were forming. The teeth were collected when they were shed. At that time the children were in school. Blood lead levels taken at the time the teeth were collected were not well correlated with parent and teachers behavior ratings at that time, or with behavior on 10 year follow up. However, lead levels in the teeth were highly correlated. The conclusion that shifted policy was that lead exposure at the time baby teeth were formed, near one year old, acted as a developmental neurotoxin, which produced an effect that the children never recovered from. Prior to this finding, it was assumed that removing lead from the body at the time of detection could reverse the effects of lead poisoning. AJim (talk) 03:12, 1 August 2017 (UTC)

What motivated Needleman to study lead?
I'm guessing he found one or more other researchers that were studying lead. There is a lecture that I've seen on YouTube where Needleman says that he met Byers at the Boston Children's Hospital and would later talk with Byers on the phone and got ideas from Byers. There might be some connection to Patterson. Phedrence (talk) 12:56, 8 November 2019 (UTC)

The Lead Industry
There is no question that lead has a long history of industrial use, but I wonder what a "lead industry" might be. We might talk about paint manufacturers, home builders, home remodelers, battery manufactures, recyclers, and users, also many mines produce lead as one of their products, also electronics manufacturers, plumbers, etc. All these diverse groups had a stake in prolonging the use of lead and lead compounds. Perhaps we could say "lead using industries"? But I think "the Lead Industry" is a step too far. --AJim (talk) 05:52, 24 August 2020 (UTC)
 * The Lead Industries Association page would be a good place for you to start learning Jamplevia (talk) 13:34, 2 February 2021 (UTC)
 * I know about that association, and about the attempts to discredit Needleman's work. My point is that there is more blame to share around than just on this defunct organization. I made the point, above, that the turning point in lead policy came when there was a consensus that lead exposure at about one year of age produced irreversible damage. It made it hard for people not directly associated with lead, landlords for instance, to claim there was no real problem. Here is a learning challenge for you. No one, to my knowledge, has explained how or why lead exposure at one year has this effect. Perhaps you have also heard that iron deficiency in this age range has been shown to have a similar long-term effect. Is there a common mechanism? Is it because of the common effect on heme production? Or is there some other common effect that more directly affects neurological development? AJim (talk) 20:50, 2 February 2021 (UTC)
