Mutagenic and carcinogenic potential of a textile azo dye processing plant effluent that impacts a drinking water source

Adsorption of Methylene Blue from Aqueous Solution Using Steam-Activated Carbon Produced from <i>Lantana camara</i> Stem

“…Similarly, this makes the water objectionable for drinking. Dyes in water stream causes allergy, dermatitis, skin irritation, which, at extreme cases, provoke cancer and mutation in humans [3]. Furthermore, the colour and the non-biodegradable nature of the spent dye baths constitute serious environmental problems.…”

The use of the Cytogenetic to Identify Mechanisms of Action of an Azo Dye in Allium Cepa Meristematic Cells

“…By means of crypt foci, some researchers [20] even showed that there was an increase in pre-neoplasic lesions in the colon of rats exposed to different concentrations of those effluents containing BDCP. Studies of chromosome aberrations using the A. cepa test-organism showed mutagenicity for several tested concentrations of an industrial effluent contaminated with the BDCP azo dye [16].…”

Reaction mechanism of azoreductases suggests convergent evolution with quinone oxidoreductases

“…Almost half of the dye used for dying fabrics does not bind to the fabric, and as a result, is lost in the effluent (Shore, 1995). As these dyes can be carcinogenic (Alves de Lima et al, 2007) their removal from the effluent is essential. This has driven investigations into both electrochemical reduction of azo dyes (Wang et al, 2010b), as well as the use of both aerobic and anaerobic bacteria for bioremediation (dos Santos et al, 2007;You et al, 2007).…”
