Hello all,
There is no described professional intoxication from the use of this =
element.
Data on its toxicity to man come from its use as the treatment of choice =
in maniaco-depressive states, and from suicidal attempts.
(Toxicologie Industrielle et Intoxications Professionnelles, Lauwerys R. =
last edition)
The only lithium compound that is reported as a severe hazard is lithium =
hydride (LiH),
which is used as a condensing agent in chemical synthesis with acid =
esters and ketones, as a dessicant (a reducing agent), and as a hydrogen =
source.=20
The hydride is a severe irritant to skin and mucous membranes because
it becomes lithium hydroxide when in contact with moisture of these =
structures.
(Occupational Medicine, Zenz Carl, last edition)
=20
The TLV-TWA proposed in 1996 for the hydride is 0.025mg/m3.
So, if you do not use the hydride, have a nice day.
Later,
