Advances in Conductometric Phase Transition Porosimetry
The paper describes advances in conductometric phase transition porosimetry (CPTP) test methods and procedures for measuring the pore size distribution of soil. Included are test methods and procedures for (1) measuring the “throat or neck” size distribution using CPTP cooling data, (2) measuring soil pore structure anisotropy using radial and axial CPTP test cells, and (3) measuring the pore ...

Cyst-Based Toxicity Tests. - XIV Application Of The Ostracod Solid Phase Microbiotest For Toxicity Monitoring Of River Sediments In Flanders (Belgium)
Abstract: In view of the need for rapid and low cost solid phase assays for contaminated sediments, a new 6 days “culture/maintenance free” microbiotest has been developed at the Laboratory for Biological Research in Aquatic Pollution at the Ghent University in Belgium, with the freshwater ostracod crustacean Heterocypris incongruens. The sensitivity of the Ostracodtoxkit FTM has ...

A NEW MEDIUM FOR CAENORHABDITIS ELEGANS TOXICOLOGY AND NANOTOXICOLOGY STUDIES, DESIGNED TO BETTER REFLECT NATURAL SOIL SOLUTION CONDITIONS
A new toxicity test medium for C. elegans is presented. The test solution is designed so that it provides a better representation of natural soil pore water conditions than currently available test media. The medium has a composition that can readily be modified to allow for studies of the influences of a range of environmentally relevant parameters on nematode biology and toxicology. Tests ...

The Toxicity Identification of Inorganic Toxicants in Real World Samples
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 pore water sample was removed or reduced significantly by the cation ...

Low-Cost Microbiotests For Toxicity Monitoring During Bioremediation Of Contaminated Soils
Abstract: This paper addresses in the first place the need to apply toxicity tests with batteries of species from different trophic levels for an (ecologically meaningful) determination of the toxic hazard of contaminated soils. Furthermore, \'direct contact\' tests must be performed as well as assays on pore waters, leachates or percolates.Most toxicity tests available to date are dependent on ...

Comparison of the Conventional Algal Assay and the Algaltoxkit FTM Microbiotest for Toxicity Evaluation of Sediment Pore Waters
Abstract : Conventional algal tests have not been utilized to their full potential for routine toxicity assessments. This is mainly due to the complexicity of these assays and the fact that many operators are still encountering practical difficulties. In view of the need for a cost-effective alternative to standard algal assays for routine testing, a new culture/maintanance free algal test was ...

Assessment of sediment quality and pore water ecotoxicity in Kebir Rhumel basin (NE-Algeria): a combined approach
The objectives of this study are to use different approaches to assess the current pollution status in the wadis of the Kebir Rhumel basin. First, sediment trace metal contents were measured by flame atomic absorption spectroscopy. Then, sediment quality was assessed on the basis of contamination assessment indexes such as: Geoaccumulation Index (Igeo), Contamination factor (Cf), Contamination ...
