Hudson River Final Study Plan Released - Waterfowl Injury Assessment
Date Posted: December 22, 2008The Hudson River Natural Resource Trustees have released the Final Study Plan for Waterfowl Injury Assessment: Determining PCB Concentrations in Hudson River Resident Waterfowl, work being conducted as part of the Hudson River Natural Resource Damage Assessment (NRDA). The Hudson River Natural Resource Trustees -- New York State, the U.S. Department of Commerce, and the U.S. Department of the Interior -- are working cooperatively to conduct the NRDA. The Final Study Plan is for an investigation of PCB contaminant levels in Hudson River waterfowl in order to determine whether PCB concentrations found in edible portions of resident ducks exceed tolerance levels established by the U.S. Food and Drug Administration (USFDA) (43 CFR 11.62(f)(1)(ii)). The study objectives are: 1) determine the concentrations of PCBs in waterfowl resident to the Hudson River; 2) determine proportions of waterfowl and waterfowl eggs having PCB concentrations that exceed the existing USFDA tolerance for those residues in poultry; and 3) determine the PCB contribution by adult mallards to juvenile mallards via PCB transfer in eggs based upon the calculation of PCB mass.
