纺织工业废水被发现剧毒
Read, Watch or Listen
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
您的衣物可能正在污染水源。纺织业常使用偶氮染料，在处理过程中会产生有毒副产物。这些毒素最终可能进入我们的饮用水和淋浴用水。做一名知情的消费者——了解您喜爱的品牌是否致力于可持续实践。
The Bottom Line
纺织业需要改头换面。研究人员建议在处理过程中使用硫酸钠代替食盐。它的效率较低，但对我们和环境来说更安全。如果您关心清洁用水，值得转发。
