Sister-chromatid exchange (SCE) and chromosome aberrations (CA) in bone marrow cells were analyzed after in vivo exposure in mice to 4 aliphatic epoxides, namely 1-naphthyl glycidyl ether (NGE), 1-naphthyl propylene oxide (NPO), 4-nitrophenyl glycidyl ether (NPGE) and trichloropropylene oxide (TCPO). These compounds were selected as being among the most mutagenic aliphatic epoxides in our previ...
River pollution due to rapid industrialization and anthropogenic activities adversely affects the aquatic organisms, especially fish. Here, we assessed the genotoxicity, mutagenicity and bioaccumulative aspects of tannery effluents in freshwater murrel, Channa punctatus, an inhabitant of river Ganges. Test specimens were collected from three different polluted sites of the river within and near...

The genotoxicity of bloom head (BHE) and leaf (LE) extracts from artichoke (Cynara scolymus L.), and their ability to modulate the mutagenicity and recombinogenicity of two alkylating agents (ethyl methanesulfonate - EMS and mitomycin C - MMC) and the intercalating agent bleomycin (BLM), were examined using the somatic mutation and recombination test (SMART) in Drosophila melanogaster. Neither ...
Municipal wastewaters may contain a variety of genotoxic compounds, including drugs or their metabolites, PAHs, etc. Bacterial genotoxicity assays use DNA impairment as end point while micronucleus tests, conducted on eucaryotes, assess chromosome aberrations. As relatively few comparative studies exist, in this study results of the micronucleus test using the painter’s mussel (Unio pictorum) a...
Chemical components of the acetone and watery extract of Ambrosia artemisiifolia (LINNAEUS, 1753) plant, and the two identified lactones in the acetone extract: the ambrosin and dihydroambrosin, was tested for genotoxicity activities. The genotoxicity of the extract was tested on the eukaryotic model system Drosophila melanogaster using the sex-linked recessive lethal test (SLRL test). The resu...
The ability of the in vitro mammalian cell tests currently used to identify genotoxins has been shown to be limited by a high rate of false-positive results, triggering further unnecessary testing in vivo. During an European Centre for the Validation of Alternative Methods workshop on how to improve the specificity of these assays, testing at high concentrations was identified as one possible s...
