%X The utility of simultaneously extracted metals/acid-volatile sulfide (SEM-AVS) differences was investigated to explain the biological toxicity of zinc in the sediments to benthic organisms exposed in the laboratory to sediments. Amphipod Grandidierella japonica was selected to 10-day acute toxicity test for this purpose. The investigation results showed that when the molar difference between SEMZn and AVS (i.e., SEMZn-AVS) was < 0 mumol/g, the concentration of zinc in the sediment interstitial water was low and few toxic effects were observed. Conversely, when SEMZn-AVS exceeded 0 mumol/g, a dose-dependent increase in the relative concentration of zinc in the pore water was detected and apparent organisms toxic effects were observed. Together, the chemical data from this study compare with observations made in short-term exposures and thus support the use of AVS as a normalization phase for predicting toxicity in metal-contaminated sediments.
