Predicting the toxicity of sediment-associated trace metals with simultaneously extracted trace metal: acid-volatile sulfide concentrations and dry weight-normalized concentrations: a critical comparison

摘要

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 concen- Trations were equally or slightly more accurate in predicting both nontoxic and toxic results in laboratory tests.
