Mr Capela e Silva:

A protocol for the detection of leadphosphate in bone after intravenous
injection of leadacetate can be found in:

Schneider B J (1968): "Lead acetate as a vital marker for the analysis of
bone growth". Amer J phys Anthropol 29 : 197 - 200.

Perhaps you can use it...  The method involves fixation in NBF or
ethylalcohol 95%, decalcification in 1% hydrochloric acid with a constant
flow of H2S, cryosectioning, staining in goldchloride and mounting in
glycerin jelly. Can't give you a detailled protocol: don't have it...


Detection of lead in "soft tissues": lead salts are precipitated as
leadchromate  after fixation in Regaud's fixative. These precipitates are
said to be "easy recognizable". The method is said to be sensitive and
specific...
