Abstract :The toxicity of a sediment pore water and an effluent was characterized using Toxicity Identification Evaluation (TIE) procedures. Both samples exhibited acute toxicity to the freshwater crustaceanThamnocephalus platyurus. The TIE approach was conducted using an enlarged battery of fractionation tests. Toxicity of the ...
During a 12 months period in 1996-1997, sediments were collected from 12 stations on the river Seine, from Paris to the estuary in Le Havre, and from 7 stations along the rivers Marne, Eure and Commerce. Pore waters were extracted by centrifugation for performance of the bioassays on the interstitial waters. ...
Treatability Study Design and NA Parameter Analysis Sediment pore water samples were collected at depths of 1, 5 and 8 feet for use in sterile control and non-amended (i.e., NA) microcosms that were incubated in an anaerobic chamber for 9 months. Initial CVOC concentrations in the microcosms were approximately 2,000 parts per billion (ppb). The ...

This study describes the design, deployment, and application of a modified equilibration dialysis device (peeper) optimized for sampling pore waters in acid sulfate soils (ASS). The modified design overcomes the limitations of traditional-style peepers, when sampling firm ASS materials over relatively large depth intervals. ...
Received for publication September 15, 2008. Restoration of wetland hydrology can produce ecological benefits but may have unintended consequences. We examined effects of altered water level on release of dissolved reactive phosphorus (DRP) and greenhouse gases (GHG) in soil cores from a marsh being evaluated for restoration. We also measured field concentrations of DRP and other constituents in ...
A load cell located around the middle of the top boundary provides data to deduce the normal and shear stresses as well as the pore-water pressures.A sample set of results are presented to illustrate some of the advantages of this new simple shear device. The advantages include the ease of specimen preparation, the determination of the stress ...
