Sorption and toxicity reduction of pharmaceutically active compounds and endocrine disrupting chemicals in the presence of colloidal humic acid
This study investigated the toxicity changes and sorption of pharmaceuticals and endocrine disrupters in the presence of humic acid (HA). For the sorption experiment, a dead end filtration (DEF) system was used to separate bound and free-form target compounds. An algae growth inhibition test and E-screen assay were conducted to estimate the toxic effect of pharmaceutically active compounds ...

Shifting from the Conventional ISO 8692 Algal Growth Inhibition Test to the Algaltoxkit FTM Microbiotest ?
Abstract :Comparison is made between results of tests performed using the conventional algal growth inhibition test according to ISO 8692, in 250 ml Erlenmeyer flasks and based on laboratory algal cultures, with electronic counting of the algal cells (N), and those obtained with the Algaltoxkit-F™ tests using algal beads, long cells and Optical Density (OD) measurements. The exercise ...

Sensitivity Comparison of the ISO Daphnia and Algal Test Procedures with Toxkit Microbiotests
Abstract : A short comparative study has been made on the sensitivity of 2 conventional bioassays (the ISO Daphnia magna immobilization test and the ISO algal growth inhibition test with Scenedesmus quadricauda) and 3 Toxkit microbiotests : the Daphtoxkit F™ magna, also with D. magna, the Thamnotoxkit F™ with the crustacean Thamnocephalus platyurus, and the Algaltoxkit F™ assay ...

Toxicity Monitoring of the Scheldt and Meuse Rivers in Wallonia (Belgium) by Conventional Tests and Microbiotests
Abstract : The Microtox acute toxicity test using the luminescent bacterium Vibrio fischeri, was chosen as a complementary descriptive parameter of toxic pollution in the framework of monitoring surface water quality in Wallonia, Belgium. In order to examine the samples on a routine basis, ensure a cost-effective approach adapted to the dilution effects, and enhance the sensitivity of the system, ...

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 ...

Quantitative risk assessment for contaminated sites in Spain
Environmental Quantitative Risk Assessment is one of the key factors in the Decision Making Process for contaminated sites. Numerous decisions have to be made before, during and after conducting a quantitative risk assessment.Risk assessment is based on the information gathered previously: Historical information (Phase I) Site characterization (Phase II) Toxicological ...
