The relative abilities of sediment concentrations of simultaneously extracted trace metal: acid‐volatile sulfide (SEM: AVS) and dry weight‐normalized trace metals to correctly predict both toxicity and nontoxicity were compared by analysis of 77 field‐collected samples. Relative to the SEM:AVS concentrations, sediment guidelines based upon dry weight‐normalized concentrations were equally or slightly more accurate in predicting both nontoxic and toxic results in laboratory tests.
