Abstract :The application of a battery of microbiotests i.e. Microtox test, Daphtoxkit F™, Algaltoxkit F™ and Mutatox test in parallel and in combination with chemical methods is discussed as a tool for the development of integrated monitoring and water pollution control. ...
cote=ENV/JM/MONO(2018)4&doclanguage=en The Testing Program for the Testing of Manufactured Nanomaterials tested 11 manufactured nanomaterials to generate information, including their physico-chemical properties, environmental fate, and environmental and mammalian toxicity. The purpose of the evaluation was to review the ...
For this reason, we have opted to evaluate toxicity of wastewater samples using a battery of biotests. In fact, genotoxicity was assessed using three tests: Vitotox, comet and micronucleus assays. The input and output of wastewater treatment plants induced a strongly genotoxic effect on the Salmonella typhimurium TA104 prokaryotic Vitotox assay. ...
We estimated toxicity, cyto‐ and genotoxicity of bulk sediments from the Yenisei River in laboratory bioassay based on using several endpoints of aquatic plant Elodea canadensis (Elodea). ...
The removal of organic compounds was measured by the following parameters: adsorbable organically bound halogens (AOX), total phenols, chemical oxygen demand (COD), dissolved organic carbon and absorbance values in the UV-visible spectral region. Moreover, ecotoxicity and genotoxicity tests were conducted before and after treatment with ozone and ozone/UV. ...
The study evaluated the safety of reclaimed water using health risk assessment and biotoxicity tests. The reclaimed water was produced from reverse osmosis and used in industrial and miscellaneous purposes. ...
The proposal is based mainly on recommendations of an European ring test performed in 2007, the work carried out in the CEN/TC 292/WG 7 standardization working group and the results of various research projects regarding the ecotoxicological characterization of waste performed mainly in France and Germany. Examples are provided showing that, using this approach, a distinction ...
UV/H2O2 treatment can be part of the process converting surface water to drinking water, but would pose a potential problem when resulting in genotoxicity. This study investigates the genotoxicity of samples collected from the water treatment plant Andijk, applying UV/H2O2 treatment with an electrical energy dose of 0.54 kWh/m3 and a H2O2 dose of 6 mg/l. ...
This study was conducted to examine the genotoxicity and the influence of silver nanoparticles (AgNPs) contamination when drinking water is exposed to five different disinfection treatments: chlorine, chlorine dioxide, ozone, ozone/chlorine and ozone/chlorine dioxide. ...
In this study, we analysed the genotoxic and cytotoxic effects of treated tannery wastewater using the micronucleus (MN) test in fish erythrocytes (Bryconamericus iheringii) and the Allium cepa test system. ...
Additionally, the genotoxicity test with Bacillus subtilis M45 Rec- and H17 Rec+ strains was performed. The obtained results showed that none of the surfactants studied was genotoxic at the concentration 1000 mg l-1. On the basis of toxicity tests to aquatic organisms all tested anionic surfactants were harmful ...
This study aimed at the investigation of genotoxic effects of swine effluents from different stages of a treatment system for swine wastes through bioassay of stamen hairs and micronuclei in Tradescantia (clone BNL 4430). No significant differences (p≥0.05) regarding the genic mutations were found in the bioassay of stamen hairs, independently of the effluent analysed. For the ...
This study focused on clarifying the genotoxicity level of environmental water and its release source by using the umu test provided in ISO13829. Although a genotoxicity index “induction ratio (IR)” is used in ISO13829, we normalised it to make it possible to compare various environmental water quantitatively to each other as a new index ...
This study assessed genotoxic risk associated with the possible release of genotoxic compounds into water from PET bottles during SODIS, using the Ames fluctuation test. Negative genotoxicity results were obtained for water samples that had been in PET bottles and exposed to normal SODIS conditions (strong natural sunlight) over ...
The study was performed to evaluate the potential genotoxic effect of lavender on Vicia faba root meristems by genotoxicity tests (comet assay and micronuclei test) and to evaluate microbial diversity fluctuation by Restriction Fragment Length Polymorphism (RFLP) molecular analysis on ecological, biological and conventional soil. ...
The contamination effects on soil functional qualities and plant nutrition were evaluated; furthermore DNA damage with short-term genotoxicity tests and DNA biosensor on polluted soils and gravitational water, was detected. The genotoxic effects were evaluated on Vicia faba seedlings by two different short-term tests: comet assay ...
Ames' mutagenicity and micronucleus genotoxicity tests came out negative at 50 mg and 2000 mg/kg doses in Salmonella and bone marrow of IRC mice. ...
