Citaat:
Beethoven suffered from a toxic overload of lead
Researchers at the U.S. Department of Energy's Argonne National Laboratory have found elevated amounts of lead in bone fragments belonging to 19th Century composer Ludwig von Beethoven, consistent with their earlier finding of massive amounts of lead found in his hair. These results confirm the cause of his years of chronic debilitating illness.
The bone fragments, confirmed by DNA testing to have come from Beethoven's body, were scanned by X-rays from the Advanced Photon Source at Argonne, which provides the most brilliant X-rays in the Western Hemisphere.
A control bone fragment sample from the same historic period was also examined.
Both bone fragments were from the parietal section – the top – of the skull.
" The testing indicated large amounts of lead in the Beethoven bone sample, compared to the control," said Bill Walsh, at the Pfeiffer Treatment Center in Warrenville, and director of the Beethoven Research Project.
The findings confirm the earlier work done on the hair samples.
In addition, the researchers found no detectable levels of either cadmium or mercury – both considered possibilities for causing Beethoven's illness – in either the bone fragment or the hair.
" The finding of elevated lead in Beethoven's skull, along with DNA results indicating authenticity of the bone/hair relics, provides solid evidence that Beethoven suffered from a toxic overload of lead," Walsh said. " In addition, the presence of lead in the skull suggests that his exposure to lead was not a recent event, but may have been present for many years."
The half life of lead in the human body is about 22 years, with 95 percent of "old" lead residing in the skeletal structure.
Beethoven experienced a change of personality and abdominal illness in his late teens and early 20s that persisted throughout his adult life. His abdominal symptoms and autopsy findings are both consistent with lead poisoning, Walsh said.
There have been documented cases of deafness resulting from lead poisoning, but this has been a relatively rare occurrence. There is no solid evidence that lead poisoning was a cause of Beethoven's deafness, Walsh said.
" Beethoven saw physician after physician in search of a cure for his physical ailments," said Walsh. In fact, in a letter to a friend, he expressed the wish that after his death, researchers would use his remains to help determine the cause of his illness so that others would not have to suffer as he did. " Beethoven suffered from bad digestion, chronic abdominal pain, irritability and depression. Since he died in 1827 at age 57, there has been much speculation but no proof of the cause of his illnesses and death."
Researchers performed the elemental X-ray fluorescence analysis at an Advanced Photon Source X-ray Operations and Research beamline.
" The APS is the best machine in the country to perform the research in this detail," said Ken Kemner, one of the Argonne researchers involved in the project. The group used microimaging to look at the distribution of lead in and on both the bone fragment and the hair to identify the presence of any surface lead, and found none, confirming incorporation of lead in the bone and hair.
een nieuwe conspiracy ...
Wie waren de vijanden van Beethoven?
Waarom moest hij dood ?
...
of heeft hij gewoon als kind zijn spoelgoed, met loodhoudende verf opgegeten en is zijn loodvergiftiging een gevolg van onwetendheid, onoplettendheid ?
of zelf teveel loodhoudende witte verf in zijn kapsel gesmeerd ...
dat laatste doet me weer aan iemand denken,
grrrr ....
kom je via Beethoven toch weer bij de @#$%^& terecht
