| Abstract |
The interstitial water toxicity approach is a multiphase procedure for assessing sediment toxicity using interstitial (i.e., pore) water. The use of pore water for sediment toxicity assessment was based on the strong correlations between contaminant concentrations in pore water and toxicity (and/or bioaccumulation) of sediment-associated contaminants by benthic macroinvertebrates. The approach combines the quantitation of pore water toxicity with toxicity identification evaluation (TIE) procedures to identify and quantify chemical components responsible for sediment toxicity. TIE involves recently developed procedures for the identification of toxic compounds in aqueous samples containing complex mixtures of chemicals. In the interstitial water toxicity method, TIE procedures are implemented in three phases to characterize pore water toxicity, identify the suspected toxicant, and confirm toxicant identification. |
