Assimilation of Selected PAH and PCB Congeners Sorbed to Sediment by Benthic Invertebrates

Abstract

Methods have been developed for removing and manipulating fecal pellets, and techniques for measuring organic carbon in sediment and fecal pellets and lipid content in Diporeia have been learned. A simple and time efficient extraction procedure has been developed to extract 14C-B(a)P and 51Cr from sediment, Diporeia and fecal pellets. In addition, experiments have shown that 51Cr can be used as a conservative tracer for Diporeia and sediment. Good progress has been made in developing the basic methods involved in determining assimilation efficiencies and preliminary data have been collected for the direct measurement and dual-labeled approaches independent of one another.
