Effects of azo dye on simultaneous biological removal of azo dye and nutrients in wastewater [PDF]
Royal Society Open Science, 2018 The potential disrupting effects of Azo dye on wastewater nutrients removal deserved more analysis. In this study, 15 days exposure experiments were conducted with alizarin yellow R (AYR) as a model dye to determine whether the dye caused adverse effects on biological removal of both the dye and nutrients in acclimated anaerobic–aerobic ...

Azo Dyes and Heinz Bodies [PDF]
Occupational and Environmental Medicine, 1957 No general hypothesis has been advanced to explain the underlying cause of the appearance of Heinz bodies in erythrocytes. The initial observation of Riess (1882) on a case of potassium chlorate poisoning was followed by that of Heinz (1890) who administered phenylhydrazine to animals.
