ENGINEERS THROUGH A JOINT COMMITTEE TO PREVENT DUPLICATION OF EFFORT- 
EMPHASIS WILL BE ON THE DEVELOPMENT OF TECHNIQUES FOR ASSESSING 
ECOLOGICAL IMPACTS OF DREDGED MATERIAL DISPOSAL, STUDIES OF THE 
TRANSPORT AND FATE OF SEDIMENT CONTAMINANTS COMMON TO DREDGED MATERIAL 
AND AN EXAMINATION OF THE SEDIMENT QUALITY CRITERIA CONCEPT- 
A- TECHNIQUES FOR ASSESSING ECOLOGICAL IMPACTS oF DREDGED MATERIAL 
DISPOSAL 
THE OBJECTIVE OF THIS RESEARCH IS TO DEVELOP AND VALIDATE BENTHIC 
BIOASSAY PROCEDURES FOR USE IN THE 404 AND OCEAN DUMPING PERMIT 
PROGRAMS- THESE PROCEDURES WILL BE USED TO MEASURE ACUTE AND CHRONIC 
EFFECTS AND BIOACCUMULATION- EMPHASIS WILL BE GIVEN TO SIMPLIFICATION 
OF BENTHIC BIOASSAYS CURRENTLY IN USE- 
B- TRANSPORT AND FATE OF SEDIMENT CONTAMINANTS ComMMON TO DREDGED 
MATERIAL 
THE OBJECTIVE OF THIS RESEARCH IS TO DETERMINE IF TOXIC POLLUTANTS 
FROM CONTAMINATED SEDIMENTS ARE A PROBLEM TO MAN: THIS RESEARCH WILL 
Focus ON PCB’S To DETERMINE THE RATE OF UPTAKE OF PCB’s FROM 
CONTAMINATED BOTTOM SEDIMENT BY ESTUARINE ORGANISMS; THE TRANSFER OF 
PCB’S FROM INFAUNAL TO PREDATOR SPECIES; AND THE FACTORS WHICH 
INFLUENCE THE MOVEMENT OF THIS CHEMICAL FROM BOTTOM SEDIMENTS TO 
ESTUARINE FOOD CHAINS OF HUMAN HEALTH IMPORTANCE: THIS RESEARCH WILL 
PROVIDE INFORMATION ON ECOLOGICAL RELATIONSHIPS ASSOCIATED WITH PCB 
CONTAMINATION IN ORDER TO IMPROVE THE BASIS FOR REGULATORY DECISIONS 
CONCERNING DREDGED MATERIAL DISPOSAL-
