TL;DR: In this paper, the specific case of aromatic amines arising from the reduction of the azo bond of azo colorants is addressed, with emphasis on the recalcitrance of azos dyes, their demonstrated vulnerability to azos bond reduction through different mechanisms and the lack of data on the biodegradability of the resulting amines.

TL;DR: In this article, photo-degradation and biodegradability have been studied for three different families of non-biodegradable textile dyes (Intracron reactive dyes, Direct dyes and Nylanthrene acid dyes) using VUV photolysis.

TL;DR: This case study was carried out on a conventional biological treatment plant (Alès, France) and focused on a set of eleven drugs representing the main therapeutic classes, finding a good agreement between MEC and predicted environmental concentration (PEC) values for seven of the eleven investigated drugs in STP effluent.

TL;DR: Chitosan is an amino-polysaccharide with highly efficient properties for the binding of metal ions and anionic dyes and has been used for the recovery of mercury from dilute solutions at initial pH 5 and Reactive Black 5 (RB5, anionic dye) at pH 3 as discussed by the authors.

TL;DR: A comprehensive overview of human health risk of drug residues and endocrine disruptors in drinking water is given but future European research will focus on genotoxic and cytotoxic anti-cancer drugs and on the induction of genetic resistance by antibiotics.
