Aqueous slurries of a test sediment spiked withdibenz[a,h]anthracene, 2,4,5,2',4',5'-hexachlorobiphenyl, p.p'-DDE, orphenanthrene were subjected to decontamination experimentation. The spikedsediments were agitated at elevated temperatures for at least 96 hours inthe presence of either of the two contaminant-absorbing media: clusters ofpolyethylene membrane or lipid-containing semipermeable devices (SPMDs).The effects of treatment temperature and surface area of media on theremoval of contaminants were explored. This work is part of a largermethodology for whole-sediment toxicity identification evaluation (TIE). Amethod is being sought that is capable of detoxifying sediments withrespect to organic contaminants...
