A Multidisciplinary Effort Linking the Impact of Sediment Contaminant Mixtures on Toxicological Response with Genetic Adaptation

EPA Grant Number: R826399E02
Title: A Multidisciplinary Effort Linking the Impact of Sediment Contaminant Mixtures on Toxicological Response with Genetic Adaptation
Investigators: Coull, Bruce C. , Chandler, G. Thomas , Decho, Alan , Quattro, Joseph M. , Shaw, Timothy J.
Institution: University of South Carolina at Columbia
EPA Project Officer: Winner, Darrell
Project Period: March 1, 1998 through August 31, 2000
RFA: EPSCoR (Experimental Program to Stimulate Competitive Research) (1997)
Research Category: EPSCoR (The Experimental Program to Stimulate Competitive Research)

Description:

Objective:

The goal of this study was to evaluate the impact of contaminant mixtures (as heavy metals and organic compounds) on toxicity and genetic adaptation in infaunal estuarine organisms. The first step towards meeting this goal was to expand our faculty with the addition of Dr. John Ferry, an environmental chemist who specializes in the behavior of organic contaminants in natural systems. Dr. Ferry joined our faculty in the fall of 1998 and has begun collaborative projects with the co-principal investigators (PIs) in support of the U.S. Environmental Protection Agency (EPA) research objectives (see below). The second step was to begin to integrate current studies of toxic impact of metal mixtures (Chandler, Shaw, and Decho) and genetic adaptation to contaminant loads (Chandler, Coull, and Quattro) into a broader study of contaminant mixtures. The initial results of these efforts are reflected in the expansion of our ongoing studies to include: the phase association and transport of organic contaminants in natural waters (Shaw, Alegria, and Cowan) and the fate and impact of pharmaceuticals (Ferry) in natural waters. While the component projects are detailed below, it is important to note that this collaboration has resulted in the submittal and funding of several multi-investigator proposals to both EPA and the National Oceanic and Atmospheric Administration (NOAA). The early success of this project, and the rapid integration of Dr. Ferry into the project, would not have been possible were it not for the ongoing research in environmental toxicology, environmental chemistry, genetics, and benthic ecology here at the University of South Carolina (USC).
