Abstract Azo dyes are of environmental concern due to their degradation products, widespread use, and low‐removal rate during conventional treatment. Their toxic properties related the nature position substituents with respect aromatic rings amino nitrogen atom. The Disperse Red 1 13 were tested for Salmonella mutagenicity, cell viability by annexin V, propidium iodide in HepG2 aquatic toxicity assays using daphnids. Both positive assay, suggestion was made that these compounds induce mainly...
Azo dyes constitute the largest class of synthetic dyes. Following oral exposure, these can be reduced to aromatic amines by intestinal microflora or liver enzymes. This work identified products formed after oxidation and reduction dye Disperse Red 1, simulating hepatic biotransformation evaluated mutagenic potential resultant solution. Controlled electrolysis was carried out on solution using a Potentiostat/Galvanostat. HPLC-DAD GC/MS were used determine generated oxidation/reduction...
Abstract Glyphosate‐based herbicides are the most commonly used worldwide because they effective and relatively nontoxic to nontarget species. Unlimited uncontrolled use of such pesticides can have serious consequences for human health ecological balance. The present study evaluated acute toxicity genotoxicity 2 glyphosate‐based formulations, Roundup Original (Roundup) Glyphosate AKB 480 (AKB), on different organisms: cucumber ( Cucumis sativus ), lettuce Lactuca sativa tomato Lycopersicon...
The treatment of textile effluents by the conventional method based on activated sludge followed a chlorination step is not usually an effective to remove azo dyes, and can generate products more mutagenic than untreated dyes. present work evaluated efficiency genotoxicity/mutagenicity dyes Disperse Red 1, Orange 13 from aqueous solutions. comet micronucleus assays with HepG2 cells Salmonella mutagenicity assay were used. degradation dye molecules after same was also evaluated, using...
Abstract Textile manufacturing is one of the most polluting industrial sectors because release potentially toxic compounds, such as synthetic dyes, into environment. Depending on class their loss in wastewaters can range from 2% to 50% original dye concentration. Consequently, uncontrolled use dyes negatively affect human health and ecological balance. The present study assessed toxicity textile Direct Black 38 (DB38), Reactive Blue 15 (RB15), Orange 16 (RO16), Vat Green 3 (VG3) using...
Contamination of natural waters has been one the major problems modern society and textile industry is rated as an important polluting source, due to generation large amounts wastewaters. The aim this study was assess dyes Reactive Blue 19 (RB19, anthraquinone dye) Red 120 (RR120, azo in terms potential induce adverse effects on aquatic organisms humans. Thus, these were tested using following assays: Microtox assay (Vibrio fischeri); brine shrimp (Artemia salina); Daphnia similis; Comet...
Azo dyes are the largest class of extensively used by industries despite their mutagenic potential for humans. As such, natural have been reemerging as an important alternative to human safety. However, limited studies focused on effect environment, thus ecotoxicological investigation is imperative. Here, we aimed evaluate toxic effects induced synthetic azo dye Basic Red 51 (BR51) in comparison with erythrostominone (Ery) microcrustacean Daphnia magna, a standard organism assess risk...
It is relatively recent that tail coiling assay in zebrafish (Danio rerio) embryos has been proposed as an alternative method to screen for developmental neurotoxicity (DNT) induced by chemicals. Despite the considerable use of method, there no consensus related most suitable age and other experimental parameters. Non-exposed were videotaped tail-coiling activity from 18 54 h post-fertilization (hpf) after exposure positive control candidates (caffeine, fluoxetine, tricaine (MS-222)) organic...
The water produced by the Cristais River Drinking Water Treatment Plant (CR-DWTP) repeatedly mutagenic responses that could not be explained presence of disinfection byproducts (DBPs) generated reaction humic acids and chlorine. In order to determine possible role chlorinated dye products in this activity, solutions a black commercial product (BDCP) composed C.I. Disperse Blue 373, Orange 37, Violet 93, chemically reduced BDCP (R-BDCP) were manner similar used CR-DWTP. resulting extracted...
