The BIONET.TOXICOLOGY newsgroup is archived and is searchable. The subject
of LD50s has come up several times in the past. Try doing a search using
LD50 as a keyword. Regarding programs to calculate LD50, I am sure some
exist, although I don't know of any offhand. Most of the commonly used
graphing programs (SigmaPlot, Cricket Graph, SlideWrite, etc.) can be used
to do this.
Best of results,
