Poisoned herbarium specimens

Is there a mean to determine if a dried specimen has been submitted to
poisoning using toxic stuff as mercuric chloride or DDT.  There is not
indication of such treatment on the sheet but I have some doubt about the
safeness of these specimens.

Thanks in advance for any help.
