Title: Field-verification program (aquatic disposal): comparison of field and laboratory bioaccumulation of organic and inorganic contaminants from Black Rock Harbor dredged material. Final report

Abstract

The utility of laboratory tests for predicting bioaccumulation of contaminants in the field was evaluated by comparing the identities, relative abundances, and quantities of organic and inorganic contaminants accumulated by organisms exposed to dredged material in both laboratory and field studies. The organisms used were Mytilus edulis (a filter-feeding bivalve) and Nephtys incisa (a benthic polychaete). These organisms were exposed in the laboratory and in the field to a contaminated dredged material from Black Rock Harbor (BRH), Connecticut. Both organisms had positive and negative attributes for these exposure studies. Mytilus edulis appeared to reach steady-state in laboratory-exposure studies. However, the determination of field-exposure concentrations was precluded due to limitations on obtaining an integrated water sample during the exposure period in the field. Nephtys incisa did not appear to reach steady-state in laboratory studies and, although field-exposure data (sediment concentrations) were obtained, the exposure zone for these organisms could not be determined. Estimates of field exposures were made using laboratory-derived exposure-residue relationships and residues from field-exposed organisms. These field-exposure estimates were compared with those estimated using exposure data from the field. A comparison of these estimates showed the same general trends in the exposure-residue relationships from the laboratory and the fieldmore » and further supports the laboratory predictive approach.« less
