   One interesting use of herbarium specimens is to trace conserved 
pollutants through time.  Unfortunately, it is destructive, and one has 
to be sure the specimens were stored in such a way that they did not 
receive contamination after collection.  Geert Raeymaekers did this for 
sulfur for part of his Ph. D.:  Raeymaekers, G. L. M.  *DATE 1986. 
*TITL Eco-physiological effects of simulated acidic rain and lead on 
Pleurozium schreberi (Hedw.) Brid.  *PUBL Ph. D. Dissertation, Michigan 
Technological University, Houghton. 126 Pp.
   I think he published it, but I haven't been able to figure out which 
publication contains it.  You can contact him at
