New benzotriazoles generated during textile dyeing process: Synthesis, hazard, water occurrence and aquatic risk assessment

JOURNAL OF HAZARDOUS MATERIALS, 403.

By: J. Vendemiatti *, N. Camparotto *, C. Vidal *, J. Cristale *, E. Agapito*, A. Oliveira*, E. Rodrigues *, C. Montagner *, G. Umbuzeiro n, P. Prediger *

author keywords: Chlorinated by-product; Toxicity; Disperse azo dye; Textile discharge; 2-Phenylbenzotriazole
MeSH headings : Animals; Coloring Agents / toxicity; Fresh Water; Humans; Mutagenicity Tests; Mutagens; Risk Assessment; Textile Industry; Textiles; Triazoles; Water; Water Pollutants, Chemical / analysis; Water Pollutants, Chemical / toxicity
TL;DR: Two new phenylbenzotriazoles, non-Cl PBTA-9 and PBta-9, derived from the dye C.I. Violet 93 were synthesized and chemically/toxicologically characterized and were more mutagenic than the parental dye in the Salmonella/microsome assay in the presence of metabolic activation (S9).
