Researchers at the University of Massachusetts Amherst report that electrochemical treatment of textile industry wastewater can generate hazardous levels of toxic byproducts. In a study published today, the team found that treating common Azo dyes with electrochemical electrodes in the presence of chloride, often added as table salt to improve conductivity, produced chloroform and bromoform at hundreds of parts per billion. These concentrations reached about three times the allowable limit for human exposure in drinking water or showers, and, when bromine was present in dyes, more than ten times the U.S. EPA regulatory limit for trihalomethanes. The authors recommend alternative salts, such as sodium sulfate, despite lower efficiency.

Why This Matters to You

Your clothes might be contributing to water pollution. The textile industry often uses Azo dyes, which can create toxic byproducts when treated. These toxins can end up in our drinking water and showers. Be an informed consumer - check if your favorite brands are committed to sustainable practices.

The Bottom Line

The textile industry needs to clean up its act. Researchers suggest using sodium sulfate instead of table salt in the treatment process. It's less efficient, but safer for us and the environment. Worth forwarding if you care about clean water.
