NCAC-SOT Fall Symposium

December 11, 2000

This symposium will present new approaches for predicting biological activity and toxicological properties of chemicals.  It will also facilitate discussion between scientists who are developing new models and those who would potentially use them.  These tools have potential application for product development, screening of large numbers of untested chemicals, and for setting priorities for more in-depth testing.  Model development helps to identify structural features of molecules that are related to biological activity and toxicity.  Such information helps to identify research that would further improve the predictiveness of models.
