Some researchers believe that behavioral and neurological defects exhibited
by most of the emperors of Rome between A.D. 15 and 225 were the effects of
lead poisoning. In those times, lead was used for water ducts, utensils,
ornaments, wine storage, coins and jewelry. Might explain the high levels of
lead in his hair... Didn't he drink a lot of wine? Maybe eat off of lead
pewter plates and drink out of lead mugs?

Hello Ioan,

You are right. I did some digging and there are some references to hearing
loss however, reportedly only a couple of cases of deafness have been
documented.

The link below has some quotes from the fellow who did the analysis of
Beethoven's hair samples. It turns out they found elevated lead levels that
averaged
about 60 parts per million (ppm) in the six Beethoven hairs. According to
the
principle investigator, average Americans today have 0.6 ppm of lead in
their
hair, about 100 times less than Beethoven (unless one uses Grecian Formula
hair coloring on their hair... ;-) .
