A General Methodology for Evaluating Bed Sediments for Narcosis Toxicity

PI: Philip Gschwend, Massachusetts Institute of Technology, R Carr, USGS Biological Resources Division

Project Number:2005-R/RC-97

Start Date:2005-03-01End Date:2007-02-28

Proposal Summary

Many sediment beds in U.S. harbors remain toxic to benthic organisms. Making decisions about which areas to clean up requires ascertaining the location and extent of these toxic deposits. In this project, researchers are establishing a method for assessing the narcosis hazard posed by sediments.
