Methylene blue dye: Toxicity and potential elimination technology from wastewater

One of the popular cationic dyes that is environmentally persistent, toxic, carcinogenic and mutagenic is methylene blue (MB) dye. These drawbacks limit their industrial full-scale applications while adsorption technology was found to offer merits over others.

⚡ This is an original paraphrased summary — not copied from the abstract. Full paper available at the source link below.

• 1 It is commonly applied as synthetic dye for dyeing fabrics in clothing and textile industries and also for dyeing papers and leathers.
• 2 Sequel to the magnitude of industrial usage, a large volume of methylene blue dye containing wastewater is discharged into groundwater and surface water.
• 3 At doses more than 5 mk/kg, the monoamine oxidate inhibitory characteristics of MB dye can induce fatal serotonin toxicity in human, apart from being a threat to fauna in aquatic ecosystem.

These innovations can translate to real-world improvements in technology, infrastructure, and everyday tools.
