Center: Center for the Study of Metals in the Environment
Center Director: Allen, Herbert E.
Title: Developing a Model to Predict the Persistence of Metals in Aquatic Environments
Investigators: Di Toro, Dominic M.
Institution: Manhattan College
EPA Project Officer: Klieforth, Barbara I
Project Period: April 1, 2002 through March 31, 2005
RFA: Targeted Research Center (2006) Recipients Lists
Research Category: Targeted Research , Hazardous Waste/Remediation

Objective:

The objective of this research project is to develop the Unit World Model (UWM) for metals. As a replacement for the current methods for evaluating the effect of metals in the environment, the Center is developing a model for the behavior of metal compounds that can be used as a tool in the hazard assessment of metals and metal compounds. This model will include the physical and chemical mechanisms that control the fate and resulting bioavailability of metals discharged to natural waters. In particular, the transformations that affect metal fate and toxicity will be included.
