||The bioavailability of 2,3,7,8-TCDD from sediment to freshwater fish was studied in laboratory exposures. Carp (10g) exposed to Wisconsin River sediment (39pg/g) for 55 days accumulated 7.5 pg/g. Maintaining exposured fish in clean water for an additional 205 days resulted in depuration of 32-34% TCDD. These values compare to field data where sediments ranged from 30-200 pg/g and 1.5 kg carp (70 pg/g) depurated 55% in 325 days. Analysis of sediment, laboratory exposed fish, and Wisconsin River fish for other PCDDs and PCDFs showed residues of 2,3,7 and 8 substituted congeners selectively enriched.
