Journal ArticleDOI
Technical basis for establishing sediment quality criteria for nonionic organic chemicals using equilibrium partitioning
Dominic M. Di Toro,Christopher S. Zarba,David J. Hansen,Walter J. Berry,Richard C. Swartz,Christina E. Cowan,Spyros P. Pavlou,Herbert E. Allen,Nelson A. Thomas,Paul R. Paquin +9 more
TL;DR: In this article, the authors present the technical basis for establishing sediment quality criteria using equilibrium partitioning (EqP), which is chosen because it addresses the two principal technical issues that must be resolved: the varying bioavailability of chemicals in sediments and the choice of the appropriate biological effects concentration.
Journal ArticleDOI
Technical basis and proposal for deriving sediment quality criteria for metals
TL;DR: In this article, the acid-volatile sulfide (AVS) is used to limit interstitial water metal concentrations, and toxicity does not occur in marine and freshwater benthic organisms.
Journal ArticleDOI
Predicting sediment metal toxicity using a sediment biotic ligand model: methodology and initial application.
Dominic M. Di Toro,Joy A. McGrath,David J. Hansen,Walter J. Berry,Paul R. Paquin,Rooni Mathew,Kuen Benjamin Wu,Robert C. Santore +7 more
TL;DR: An extension of the simultaneously extracted metals/acid-volatile sulfide (SEM/AVS) procedure is presented that predicts the acute and chronic sediment metals effects concentrations.
Journal ArticleDOI
Predicting the toxicity of metal-spiked laboratory sediments using acid-volatile sulfide and interstitial water normalizations
Walter J. Berry,David J. Hansen,Warren S. Boothman,John D. Mahony,D.L. Robson,Dominic M. Di Toro,B.P. Shipley,B. Rogers,Jeffrey M. Corbin +8 more
TL;DR: In this article, the authors used acid-volatile sulfide (AVS) to predict toxicity in sediments contaminated with cadmium, copper, nickel, lead, or zinc across a wide range of sediment types.
Journal ArticleDOI
Predicting the toxicity of metal‐contaminated field sediments using interstitial concentration of metals and acid‐volatile sulfide normalizations
David J. Hansen,Walter J. Berry,Warren S. Boothman,Carol E. Pesch,John D. Mahony,Dominic M. Di Toro,D.L. Robson,Gerald T. Ankley,D. Ma,Q. Yan +9 more
TL;DR: Interstitial water concentrations of metals and simultaneously extracted metal/acid-volatile sulfide (SEM/AVS) ratios are investigated to explain the biological availability of sediment-associated divalent metals to benthic organisms exposed in the laboratory to sediments from five saltwater and four freshwater locations in the United States, Canada, and China.
