CDC Lowers Blood Lead Level Criteria for Children After Major Budget Cuts
By Carol Hill | 05/21/2012 | Budget, Economy, Health Care, Issues, Legislation, Science, Taxes | 8 CommentsBy now, most of us are onto the truth behind the Federal Reserve’s inflation information, because even if we didn’t get much beyond basic high school math, we know the price for gas and groceries have gone up a lot more than 2% the past couple years. And, we roll our eyes when the Bureau of Labor Statistics tells us the unemployment rate is 8.1%, knowing that we will have to dig through carefully culled data to get to the real unemployment story.
According to a Wall Street Journal article on May 16, the CDC has just lowered the “level of concern” (which the WSJ carelessly referred to as “the minimum threshold for lead poisoning”) for blood lead levels, to 5 micrograms per deciliter in children under 6 years of age. Before this announcement the “level of concern” was 10 µg/dl for children under 6.
I never planned to learn about lead, but my rural community has been a Superfund site for almost thirty years, and the ongoing battle has been about lead. Here are a few facts about lead to put the CDC announcement into perspective:
–According to EPA Risk Assessments done for the California Gulch Superfund site, the national average blood lead level in 1978 was 15 micrograms per deciliter, and the CDC “level of concern” was 30 micrograms per deciliter.
–Since then lead has been banned in gasoline, paint, soft drink cans, solder, and most consumer products, and as of 2010, the national average blood lead level had dropped by 85%, to about 1.8 micrograms per deciliter, and it has continued to drop. Due to the overwhelming success of of the lead bans in lowering blood lead levels, the CDC has repeatedly lowered its “level of concern” (above which a blood lead level is deemed “elevated”, not poisoned, although CDC has now proposed that the phrase “level of concern” be discontinued) to 10 micrograms per deciliter.
–According to Peter Samuel in Lead Astray: Inside an EPA Superfund Disaster, “By 1990, average blood lead levels in bodies of Americans–young, old, rich, poor, black, and white–had fallen dramatically from 13 micrograms per deciliter in the late 1970s to about 3 micrograms.”And, “In 1971, 40 micrograms per deciliter blood lead was the accepted initial level of concern for children.”
–According to the minutes from the CDC Advisory Committee on Childhood Lead Poisoning Prevention (ACCLPP), November 2011, “‘Lead poisoning’ was defined as 60 micrograms per deciliter in 1965….”
Peter Samuel also points out that, “Lead is a common element,” with “trace amounts…in most surface soil and rock.” He goes on to note that, “We know that many other elements that are harmful at high doses are helpful, or even vital, at lower doses. Intuitively one thinks that some biological processes will have positively harnessed the properties of lead in some way, since most similarly ubiquitous substances are so harnessed.” Samuel accuses the National Research Council, EPA, CDC, and ATSDR of ignoring “…a body of scientific evidence that suggests trace amounts of lead are essential for good health.”
At 10 micrograms per deciliter, currently about 1% of the nation’s children under 6 have an elevated blood lead level. But, as the WSJ notes, by lowering the acceptable level to 5 micrograms per deciliter, “an additional 200,000 children could [emphasis added] be found to have potentially [emphasis added] harmful levels of lead.” And given the budgets at stake, that may be the real reason for trying to get one more battle out of what Peter Samuel described in 2002 as “a lead poisoning problem that has already been won”.
In the minutes of the November 12, 2011 ACCLPP meeting cited above, it was noted “that actions are being taken in the House and Senate to eliminate CDC’s LPP [Lead Prevention Program] program”, noting the “urgent need for individuals to contact the Congressional representatives to stop this effort.” Apparently they weren’t successful, as the WSJ article concludes, “The CDC revision comes as funding for its lead-prevention programs was reduced from $30 million to $2 million this fiscal year….” Coincidence?
So, from 40 micrograms per deciliter level of concern in 1971, we’re now down to 5 micrograms, in a country where the average blood lead level is 1.8 micrograms. Apparently, just by changing definitions, a federal bureaucracy can justify maintaining or increasing a budget, by simply regulating a problem into existence.

Allow me to quote the result of a study entitled “Intellectual Impairment in Children with Blood Lead Concentrations below 10 μg per Deciliter” published in 2003.
“IQ declined by 7.4 points as lifetime average blood lead concentrations increased from 1 to 10 μg per deciliter.”
So what level of lead would you allow in your child’s blood?

Frank Lee hit my point exactly. While the timing of this article may purposely coincide with the Lead Care budgets being cut, that doesn’t make the work being done any less significant. I work at the CDC, and my branch studies lead in blood, and I can tell you that slashing the lead budget has more far reaching effects than the everyday “know-it-all” reporter will know. An 85% decline in blood lead levels (BLLs) is a great thing in and of itself, but the fact still remains that children can show mental impairment with even the lowest BLLs. Not to mention that while lead-based paints have been banned, many low income families live in older buildings/houses that still have lead-based paints… This article appears as though it was written without any background research into the harms of lead.

Secondly, your last paragraph is irrelevant information. As science (detection limits, technology, toxicological understandings) has improved, so have the warnings about lead’s harmful effects. It should also be noted that the blood lead level of conern for children was reduced to 5μg per deciliter, not the overall population’s level of concern.

Did you ever consider that since the science has gotten better that perhaps 5 micrograms *is* a level of concern and that we were simply wrong in the past? I thought that’d be fairly obvious but cancer studies have come a long way since the 70s.

Quoting some anonymous “scientician” who says lead is healthy in low doses doesn’t mean lead is healthy in low doses. Link a study, please. Show us some data.

Good point. This also applies to the body of evidence that indicates the health effects at low levels. The study I originally cited above was published in the highly respected New England Journal of Medicine, and can be found at: http://www.nejm.org/doi/full/10.1056/NEJMoa022848 . A more comprehensive listing of studies is available at http://www.lead.org.au/fs/Dangers_of_BPb_Level_Above_2ug_dL_and_Below_10ug_dL_20110314.pdf . I challenge the author of this article to read this listing, then try to sleep at night.

We the undersigned support the lowering of The PEL (permissable elevated lead level) in a childs blood from 10 micrograms per deciliter to 5 micrograms per deciliter. Please help stop childhood lead poisoning. Thank you.
It is my hope to see the PEL ( permissable elevated lead level) lowered from 10 micrograms per deciliter to 5. Lead laws changed in April 2010. Please educate yourselves on the DANGERS found right in some of your own homes. I am the Administrator of Julia, Lead The Way (lead poisoning awareness) on Facebook. My family and the members of our group hope to see changes that will help not only our children, but our environment and our nation. Peace~

Is there any reason this article is still up for people to read? After reading the comments and using common sense, it seems as though this article is complete hogwash and written in a very immature and unprofessional manner.
