Rapidly evolving progress in computer hardware and software has promoted the application of sophisticated chemical models to complex environmental problems. This symposium will showcase the application of computational methods, including molecular modeling of pollutant properties and reactions, kinetic simulations of complex reactions, and aqueous equilibrium modeling. Oral presentations will emphasize A) novel algorithms and models which could be applied to environmental problems, B) models and algorithms first applied to environmental problems in the last five years and C) prospectiveenvironmental applications for which only preliminary results are available.

Short abstracts (required by ACS) and extended abstracts no longer than 4 pages (required by the Division of Environmental Chemistry) must be submitted by November 3, 1999 to:
