||DDT is a persistent and toxic nonionic organic chemical commonly present as a contaminant in aquatic sediments. As a result of effluent discharges by a chemical company manufacturing DDT on the Redstone Army Arsenal near Huntsville, Alabama, the water column, sediment, and biota of the Huntsville Spring Branch-Indian Creek stream system (HSB-IC) became heavily contaminated with DDT and its metabolites, DDE and DDD. Because DDT appeared to be the primary contaminant in the sytem, an investigation was begun to evaluate equilibrium partitioning theory (EqP) as a basis for predicting the free pore-water concentrations in and toxicity of DDT-contaminated sediments for the system. These data demonstrate an effect-based EqP prediction of the toxicity of field-collected sediments contaminated by a nonionic organic compound and the potential utility of the EqP approach for developing sediment quality criteria.
