Mutagenicity Analyses of Industrial Effluents: Results and Considerations for Integration into Water Pollution Control Programs

Detecting genotoxic activity in industrial effluents using the SOS Chromotest microplate assay

“…However, petroleum refinery wastewaters are known to carry a variety of mutagenic chemicals (Houk, 1992), but even extracts of these samples were not found to be very potent in comparison to other industrial liquid wastes (McGeorge et al, 1985). And in a study conducted by Sherry et al (1994), one of two petroleum refinery effluents showed genotoxic effects with the SOS Chromotest after having been concentrated ten fold.…”

Acute, subacute toxicity and genotoxic effect of a hydroethanolic extract of the cashew (Anacardium occidentale L.)

“…The sample was considered to be mutagenic when the number of revertant colonies was at least twice the negative control yield (MI ≥ 2) and showed a significant response with ANOVA (p ≤ 0.05). When only one of these criteria was met, the sample was considered to present signs of mutagenicity, in agreement with McGeorge et al (1985). Standard mutagens used as positive controls in each experiment were 2-anthramine (2.5 g/plate), 4-nitro-ophenylenediamine (10.0 g/plate) respectively for TA97a and TA98 with and without S9, 2-athramine (2.5 g/plate) for TA100 with S9, sodium azide (2.5 g/plate) for TA100 without S9, daumycin (5.0 g/plate) for TA102 without S9 and 2-aminofluorene (10.0 g/plate) for TA102 with S9.…”

Modeling of experimental data for the adsorption of methyl orange from aqueous solution using a low cost activated carbon prepared from Prosopis juliflora

“…Several research reports revealed that very small quantities of dyes are highly toxic which causes acute disorders in aquatic organisms 7 . Uptake of textile effl uents through food chain in aquatic organisms and human beings may cause various chromosomal fractures, respiratory, mutagenic and carcinogenic problems [8][9][10] . Therefore, the wastewater containing dyes must be properly treated before being discharged into the water bodies.…”
