AS an update to my post of FEB 16 with above title-my newest blood test about 5 weeks of not reloading or shooting and doing a cleaning job on my house and gunroom-level was 41 frm 62 or 64. I'm very happy with the results and input from 1Kperday and others on value of Vitamin c. Pretty soon I'll be shooting again but outdoors and respirator until I feel comfortable. Thanks for help and also to sticky post which identified the tumbler issue.
 
My level of 53 in mid February caused me to do the same self imposed stop of all activities related to shooting and reloading. I'm giving myself 3 months, and have been doing the 1000mg vitamin C routine daily. I hope I can post similar reductions in mid May. Sold all my remaining lead bullets, moved to ultrasonic brass cleaning, and now deprime on my Hornady LNL into a water fillled jug that eliminates all dust from the process. Have to say that the Hornady Magnum sonic cleaner with nothing but water, Dawn and Lemishine does a heck of a job! Since I'm not reloading or shooting, I've been doing lots of experimenting with processes and techniques.
 
I tested 18 in February. I haven't stopped shooting altogether but I'm taking vitamin C and my range pickups are getting washed in Lemi Shine before tumbling.

Tumbling is outdoors and my loading area got a good swabbing.

Range clothes go right in the washer.

I'm also getting tested again in May.
 
Seems like we go through this exercise in logic once or twice a year here, and the misconception never go away. Check your facts.

1. You do not absorb lead through your skin, so you are either (A) eating it, or (B) inhaling it. The cure for this is to shoot outside or in well ventilated areas and wash your hands before you eat or chew your nails

2. Vitamin C does not remove heavy metals from your body. Chealation therapy will, and that is actually a slightly risky medical procedure. Getting enough calcium, zinc, and protein in your diet will help your body ABSORB LESS, but they also do not remove it, your liver is what removes toxins from your body.

D'OH! And here I thought that taking steps to avoid dust exposure was a good idea. Thanks for straightening me out...

I'll also let my doctor know that the Vitamin C is a waste of time...

Skin may not absorb lead but once it is on you, like fingers and all, it will transfer to your beefy burger and fries. Then you will eat it.

Lead dust will also collect on clothing, which you touch and rustle. You can expect dust on your clothing to puff into the air around you and you can expect skin transfer.

Lead dust does not have to be so big you see it. There is lots of dust in the air, just fly to LA and see the brown layer as you decend to the airport. There are lots of carbon products in the air from things like diesels that reduce people's breathing capacity in their lungs.

I have no idea where the Vitamin C idea came from. It would be interesting to know if any results are only due to the placebo effect.

Lead in blood

I had the blood chelation done year before last, the lead was causing my leggs and feet to have low blood circulation. After 18 treatments I no longer have that problem. A lot of the medical profession don't believe in Chleation treatments but I'm convinced, it worked for me. I wouldn't advise you do it from some of the internet sites, because there are other things it removes from your system that you need to replace. See a Dr. that specializes in the treatments. Al
 
"check here regarding the absorption of lead and lead compounds thru the skin"

24 hours exposure to get the results.

Not a realistic test by any means.

That link was one of hundreds that came up with a google search. Try google as I did and read all the others. Search for "lead absorption thru the skin" will give you all the links you wish. Sorry I picked the wrong one in your minds eye.

The main point is YES it is possible for lead compounds to be absorbed thru the skin!
 
FWIW;
I worked in a H.D. repair shop where a couple welders had elevated lead levels in their blood, prolly from working on equipment that had lead paint or galvanizing (we weren't allowed to grind or sand any metal painted yellow). Our supervisor, who was a health nut, suggested French Green Clay. One welder tried it and lowered his lead/blood levels down to "normal" with 6 months between tests (employer furnished tests/lab work). I don't know numbers, but the welder continued to use the French Green Clay (one dose in the A.M.), and recommends it to all, lead or not...
 
And after I looked at hundreds of papers a few moths ago, not a single one dealt with metallic lead being absorbed in any short term.

There is even a BS paper out there about lead form bullets left in shooting victims.

They ran blood lead levels for a few months and found out that more fragments (more surface area) resulted in more lead being absorbed.

Wat they ignored in their own data, right in the paper, was the decline in blood lead levels that started after a few months.

As the surface of the lead became isolated.


Another paper used an organic lead compound to show skin penetration.

No one could have guessed that one.:banghead:


'Big medicine' is usually at large teaching hospitals in large cities.

Guess the politics.:eek:

Add to all this that medical doctors are often not the best scientists around, and all sorts of crud comes out.

There is a reason large national medical facilities have a lot of PhDs around.
 
Guess it boils down to believe what you wish.

As I said in my post #9 here the scare is way overblown. With that said I'll side with the folks who do the studies and have the experience and knowledge. After all, without them I would not be alive today!

Yup, and Thank God they do.
 
Sorry but my information is different than yours.
According to my sources, Vitamin C IS A GOOD CHELLATOR.


Please do your own research before taking anyone's opinion. (including mine)
Here's a good start.

Yes, your information IS different from mine. You got yours from a pseudoscientific vitamin ad on google, and I got mine from trusted sources, like OSHA, Medical Journals, the EPA, and a degree in science. "Doing research" on google turns up truth AND lies. I thought everyone knew this by now.

If you look up the size of the space between the phospholipid bilayer molecules that make up your skin cells, and compare that to the HUGE molecular size of a molecule of lead, there is no feasible way the molecule could get in there, unless you have cuts on your hand. It gets in by inhalation and digestion; two functions tailor made for absorbing things into the body.

Like I said, Vitamins may help you ABSORB LESS into your body, but it will not remove it, so perhaps that is why the doctor prescribed it, although I've only read that Zinc and Calcium are good for that. If you claim that Vitamin C is a Chelator, then why is it NOT used during medical Chelation therapies???? Why would they use MUCH more dangerous chemicals and risk lawsuits? By what chemical mechanism do you propose that vitamin C even binds to the lead metal? You can argue with yourself all you want, but then you could also pick up a biology and chemistry book and look up facts.
 
This topic caught my interest.

Traditionally chelating agents have either strong dipole moments to interact with a heavy metal ion to act as a "salt" even though an ionic bond will not form in solution. Think of how hemoglobin holds onto an iron atom, that is how strongly a chelating agent needs to hold onto a heavy metal ion. Normal heavy metal cations have a +2 or +3 charge, so a molecule that would have an overall -2 or -3 charge in the correct geometry to surround half the size of the heavy metal cation work best as chelating agents.

Ascorbic Acid, aka Vitamin C has several forms, all of which have strong dipole points because of the Oxygen atoms electronegativity. In its most reduced form the C double bond O would form a strong negative area, unfortunately the ring structure in Ascorbic acid only allows two of the three oxygen atoms to be in correct geometry to interact with a metal cation.

Now I did a quick search of pubmed and encountered one article which showed Ascorbic Acid did reduce intracellular iron content, which is what you would expect from a chelating agent. I could find no studies on ascorbic acid and lead.

So, what do I think of Vitamin C as a chelating agent? File it under "possibly useful, not harmful." The human body will naturally excrete heavy metals through the kidneys and bowels (bonded to sulfates, gluconates, or bile) as a normal part of healthy filtration. Chelation therapy isn't recommended for anything short of heavy metal poisoning, so I can't say that a massive dose of Vitamin C actually caused the filtration process to move faster or not.

Have you ever taken a blood test to see if your lead level was high?
