Abstract : This paper discusses results of three laboratory studies where invertebrate animals were exposed to contaminated sediments for periods of 30 to 136 days. Sediments and animals were analyzed for metals and PCB, but not for pesticides or petroleum hydrocarbons. Lead was the only metal which showed a slight potential for transfer from sediment to organism. The data did indicate, however, that PCB in sediment is available. Bioaccumulation of PCB was affected by level of sediment contamination, characteristics of the sediment such as particle size and organic content, and life-style of the organism. Data on sediment and a clam species from a containment area near Port Arthur, Texas, are also presented. The analyses indicated only low levels of contaminants with levels in Rangia generally lower than sediment levels. These data are discussed in relation to use of containment areas of producing edible fish and shellfish or bait species. Excess animals could be used to supplement existing fish or shellfish in nearby lakes or estuaries.
