message: It is contended in the article that lead poisoning cannot have been a major source of problems in ancient Rome because the water was not allowed to stand in the pipes, flowing continuously. One must keep in mind, though, that the aqueducts were miles and miles long and this must have allowed a significant amount of lead to enter the water even if the pipes or linings developed, in time, mineral incrustation. Definitely the poisoning by the sugar substitute used, grape juice boiled down in lead pots, must have been more worrying. Nobody ever used white lead (acetate) as such, but the amounts of lead dissolved from the pots into the juice by its acidity must have been alarming, striking as it did mostly the affluent (and hence, the decision-makers...)27.116.58.18 (talk) 11:45, 15 December 2010 (UTC)
replies: text: The above implies that Roman aqueducts were constructed of or lined with lead.  I know of no instance of or reason for this.  The aqueducts were constructed of concrete, stone, brick and ceramic tile and needed no lining of any kind. The local plumbing, as in more recent times, was composed of lead pipe, but this comprised only a very small fraction of the above stated "miles and miles" the water traveled.

message: Dear Sirs,
In reading the article on lead poisoning, several ancient dates were referenced. These were said to be either "BCE" or "CE". These are supposed to mean: "Before the Common Era" (?) and " Common Era" (?).
This is offensive to Christians who have always believed the terms BC, Before Christ, and AD , Anno Domini (The Year of the Lord) were the appropriate ones to use. I wish the revisionists who wrote this article (and others like it) would stop trying to put down Christianity and use BC and AD, the correct terms we're all used to.

message: The statement "No safe threshold for lead exposure has been discovered—that is, there is no known amount of lead that is too small to cause the body harm" has no basis in fact.  Statistically speaking, it is almost a certainty that every living cell that ever did, does or will exist contains at least one atom of lead (and every other element) and likely many more. As there are about 100 trillion atoms in an average animal cell, the presence of even thousands of lead atoms per cell cannot be shown, even theoretically, to have any effect on the cell whatsoever.  More practically, there are certainly a great many studies that have found a level of lead within a creature that below which, no harmful effects have been observed.

message: This (and the root Lead entry) regularly refer to lead poisoning and lead ingestion without qualification.
Almost without exception lead poisoning refers to lead compounds, but this is not made clear.
I understand that eating lumps of lead (unless done daily to excess) does not result in lead poisoning because the human GI is not good at breaking down metallic lead. But eating lead is what this article suggests.
A biochemist should review this to clarify.
My interest is that I was shot by an air rifle as a teenager 50 years ago and the lead pellet is still in my foot.
I was told by the hospital that lead is not biologically accessible.
I should add that I am in excellent health :)  — Preceding unsigned comment added by Kenif (talk • contribs) 03:36, 26 January 2014 (UTC)

thread_title:  Lead - Biological Roles 

message: The article mentions blood levels, but there seems to be little or no info about the amount of lead exposure that would cause those blood levels, ie the regression slope factors for types of exposure (food, water, air, ...).
For example, based on the FDA's Total Diet Study, the lead intake from food for infants and toddlers is estimated at about 5 μg/day (Bolger et al. 1991), what would the corresponding blood level be? 
Some of the figures given seem to conflict with those in the lead article, btw: 
:Of ingested inorganic lead, about 15% is absorbed... In adults, 94% of absorbed lead is deposited in the bones and teeth
94% of 15% is 14.1%; the lead article on the other hand says:
:A small amount of ingested lead (1%) will be stored in bones, and the rest will be excreted by an adult through urine and feces within a few weeks of exposure. 
Not sure if this is a case of conflicting (wrong) data or conflicting definitions (for example if "94% of absorbed lead" really means "94% of lead stored in the body"). Prevalence  08:06, 9 November 2016 (UTC)

message: What confuses me is that lead poisoning is associated with hyperactivity, yet ALA is a GABA agonist.  I think it might be that just because something is a receptor agonist does not imply that the effects are equal to the effects of the actual neurotransmitter itself.  For example, Both delta aminolevulinic acid (ALA) and porphobilinogen (PBG) depressed spontaneous activity in the isolated hemisected frog spinal cord. ALA was approximately one fifth as potent as GABA in this respect ....  I suppose I need to do more research.

message: Ever since Flint Michigan I have been rather interested in the effects of lead poisoning, so this article was an educational read. I'm not sure if I skipped over it, but it may be worth mentioning in this article too that lead poisoning can also be transferred from female to child during pregnancy via calcium deposits. During pregnancy, if the mother was previously exposed to high concentrations of lead it gets stored in her bone cells and organs. During pregnancy when the unborn child is in need of nutrients the exposed females body starts to use those "stored" deposits sending it to the unborn child. This causes lead poisoning to transfer from the female to the baby. 
Here is a study that somewhat explains it, I am sure there are better ones out there that you could cite if you end up including this information! 
All in all, good article.  — Preceding unsigned comment added by Whatanerd1993 (talk • contribs) 14:13, 10 May 2018 (UTC)

CHAPTER XIX--SOME RECOLLECTIONS OF MORTALITY
One man with a gloomy malformation of brow--a homicidal worker in white-lead, to judge from his blue tone of colour, and a certain flavour of paralysis pervading him--got his coat-collar between his teeth, and bit at it with an appetite.
CHAPTER XXXII--A SMALL STAR IN THE EAST
I saw a horrible brown heap on the floor in a corner, which, but for previous experience in this dismal wise, I might not have suspected to be 'the bed.' There was something thrown upon it; and I asked what that was.
 'Tis the poor craythur that stays here, sur; and 'tis very bad she is, and 'tis very bad she's been this long time, and 'tis better she'll never be, and 'tis slape she does all day, and 'tis wake she does all night, and 'tis the lead, sur.'
 'The what?'
 'The lead, sur. Sure 'tis the lead-mills, where the women gets took on at eighteen-pence a day, sur, when they makes application early enough, and is lucky and wanted; and 'tis lead-pisoned she is, sur, and some of them gets lead-pisoned soon, and some of them gets lead-pisoned later, and some, but not many, niver; and 'tis all according to the constitooshun, sur, and some constitooshuns is strong, and some is weak; and her constitooshun is lead-pisoned, bad as can be, sur; and her brain is coming out at her ear, and it hurts her dreadful; and that's what it is, and niver no more, and niver no less, sur.
CHAPTER XXXV--ON AN AMATEUR BEAT
As is the case with most pulps or pigments, so in the instance of this white-lead, processes of stirring, separating, washing, grinding, rolling, and pressing succeed. Some of these are unquestionably inimical to health, the danger arising from inhalation of particles of lead, or from contact between the lead and the touch, or both.

thread_title:  Swallowing lead pellets 

message: Quote from the bullets section:
"Some lead-based bullets are resistant to fragmentation, offering hunters the ability to clean game animals with negligible risk of including lead fragments in prepared meat. Other bullets are prone to fragmentation and exacerbate the risk of lead ingestion from prepared meat. In practice, use of a non-fragmenting bullet and proper cleaning of the game animal's wound can eliminate the risk of lead ingestion from eating game;[139] however, isolating such practice to experimentally determine its association with blood lead levels in study is difficult."
This is misleading. Read the source ([139]) carefully. It does not say that non-fragmenting lead bullets eliminate the risk of lead poisoning. It says that lead-free non-fragmenting bullets eliminate the risk of copper poisoning. It says nothing about non-fragmenting lead bullets.

So, this looks to be a misinterpretation.
