ICF Consulting Environmental Scientists Win Two Awards from the Society of Toxicology

FAIRFAX, VA, August 2, 2000 - ICF Consulting announced today that two of its environmental scientists have received awards from the Society of Toxicology's Risk Assessment Specialty Section for outstanding presentations in risk assessment. The awards were for work presented at the Society's 39th annual meeting, which recently was held in Philadelphia. The presentations were based on work that ICF Consulting recently completed to develop better methods for determining permissible exposure limits (PELs) and dose-response assessments for toxic chemicals. Both projects used pharmacokinetic methods, which estimate the disposition of toxic chemicals through the human body.

The first award was for a presentation titled, "A Family Approach for Estimating Reference Doses/Concentrations for a Series of Related Organic Chemicals." The presentation described the work that Justin Teegaurden, Ph.D., an ICF Consulting toxicologist, performed to develop pharmacokinetic methods to streamline development of reference concentrations and reference doses for compounds that are sequential metabolites of common precursor compounds. Tip Tyler, Ph.D., of Union Carbide Corporation, Hugh Barton, Ph.D., of the U.S. Environmental Protection Agency, and Mel Andersen, Ph.D., of Colorado State University, also contributed to the study. Dr. Barton and Dr. Andersen are formerly of ICF Consulting.

The second award was presented to ICF Consulting's Ramesh Sarangapani, Ph.D., for his presentation titled, "Developing a Pharmocokinetic Model for a Biologically Based Dose-Response Assessment for Dimethyl Sulfate." Dr. Teeguarden and Matt Bogdanffy, Ph.D., of Dupont Haskell Laboratory in Newark, Delaware, also contributed to the study described in this presentation. This work is aimed at improving the scientific basis for assessing the health risks of dimethyl sulfate.

"ICF Consulting is proud to have two of its environmental scientists recognized by their peers for the contributions they have made toward building an environmentally sustainable future," said Peter Linquiti, ICF Consulting executive vice president. "Refining the methods for determining PELs and dose-response assessments is a vital contribution to progress in environmental toxicology and in environmental management as a whole."

Dr. Sarangapani and Dr. Teeguarden are based in ICF Consulting's office in Research Triangle Park, North Carolina.
