QUESTION: Different asbestos mines produce asbestos containing different lead levels 26 Mar 2008 British Columbia, Canada
I was a research microscopist in forestry technology. When the research center I worked in closed I retrained as a Live and Dried Blood Analyst. It was extremely fortunate that I did this because I had to use it to define what was causing my left side paralysis and nervous system damage that was diagnosed as MS. It has taken me 5.5 years and much testing and experimenting to completely identify all the toxins I was exposed to in my careers, not the least of which was lead, most of it being lead from asbestos.
What I discovered recently is that chrysotile asbestos contains varying amounts of lead depending on where it is mined. I found this out when I took Canadian and Rhodesian UICC chrysotile samples with me for Vega Testing to see if I had asbestos toxicity. I tested toxic for the Rhodesian chrysotile. This got me wondering what the difference was between the 2 asbestos samples. The difference was the levels of lead. I have documented what asbestos looks like in phase contrast and dark field modes and what it looks like in the blood. All components in the asbestos appear in the blood. The problem in the body appears to be that when the asbestos is separated into its magnesium/silica and lead components the lead is not removed but continues to build up and circulate in the body unlike the magnesium/silica that is eventually removed through the skin. So in reality the asbestos problem is a lead problem. When one considers that 3-5 million tons of asbestos a year were/are mined then it is not hard to see this could be a huge problem. I have also documented what happens in the body as lead levels increase. I have also found fairly safe ways of removing the lead. Other than for the unfortunate individuals I have seen who have been affected by lead and asbestos most people don't seem to be concerned with this information although they claim to be representing the cause for asbestos or lead. I thought I would try again and see if I get a response. I would be quite happy to send a CD with the images I have if you are interested and can give me an address to mail it to.
Further I was wondering if by any chance you people have come across information documenting lead in asbestos. I have hunted all over the internet and have found not even a whisper that this may be the case, except perhaps for the disbanded Canadian Asbestos Institute that claimed an undefined purity for the Canadian asbestos. Indeed it does have less lead, but is that good??

WOW!! I had no idea that different asbestos mines produce asbestos containing different lead levels. In a 214 page document on chrysotile asbestos published by the Australian federal health department (see www.nicnas.gov.au/Publications/CAR/PEC/PEC9/PEC_9_Full_Report_PDF.pdf), lead is not mentioned once.
What kind of lead levels are we talking about here? Can you please give some examples from laboratory analysis of the lead content? I would be fascinated to receive the data. This sounds like the makings of a very important fact sheet that, if you were able to write it, we would be very glad to publish on our website.
Is the lead level the kind of lead level that would warrant even occupational blood lead monitoring? (In Australia, a hazardous substance which contains more than 1% lead would warrant blood lead monitoring - is that the kind of lead concentration you have found in asbestos? Have you ever found any results of such blood lead monitoring from asbestos miners or manufacturing workers?
How did you come across the individuals you mention that have both lead and asbestos exposure? How did they find out they were exposed to both lead and asbestos? Do you have any blood lead data for yourself or anyone else with the double exposure due to lead in asbestos? Do you think we should create an egroup for people who have been exposed to lead in asbestos or simply to both lead (from any source) and asbestos? Would you be willing to be a moderator of the egroup and to promote it so that people with the two exposures could find somewhere on the web that had information relating specifically to their dual exposures?
I look forward to hearing back from you and receiving any information you have on the subject.
Thanks for your email.
All the best
