Waterless Dyeing and In Vitro Toxicological Properties of Biocolorants from Cortinarius sanguineus

JOURNAL OF FUNGI, 8(11).

By: M. Herrala*, J. Yli-oyra*, A. Albuquerque*, N. Farias*, D. Morales*, R. Raisanen*, H. Freeman n, G. Umbuzeiro*, J. Rysa*

author keywords: bloodred webcap; dermocybin; dermorubin; emodin; fungal colorants; supercritical CO2; toxicity; waterless dyeing
TL;DR: The results indicate that dermocybin and dermorubin possess the technical and toxicological properties needed for consideration as synthetic dye alternatives under conditions that are free of wastewater production. (via Semantic Scholar)

ENVIRONMENTAL AND MOLECULAR MUTAGENESIS, 62(1), 52–65.

By: G. Umbuzeiro n, D. Morales*, F. Vacchi*, A. Albuquerque*, M. Szymczyk n, X. Sui n, N. Vinueza n, H. Freeman n

Contributors: G. Umbuzeiro n, D. Morales*, F. Vacchi*, A. Albuquerque*, M. Szymczyk n, X. Sui n, N. Vinueza n, H. Freeman n

author keywords: anthraquinones; azo dyes; microplate agar; Salmonella; microsome assay
MeSH headings : Coloring Agents / adverse effects; Coloring Agents / chemistry; Molecular Conformation; Mutagenesis / drug effects; Mutagenicity Tests / methods; Mutagens / adverse effects; Mutagens / chemistry; Salmonella typhimurium / drug effects; Salmonella typhimurium / genetics; Solubility
TL;DR: It is proposed that dyes should be tested in a tiered approach using YG1041 followed by TA97a, TA98, and TA100 in concentration‐response experiments, which provides additional information on the dye mutagenicity database available in the literature. (via Semantic Scholar)

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).

Towards a reliable prediction of the aquatic toxicity of dyes

ENVIRONMENTAL SCIENCES EUROPE, 31(1).

By: G. Umbuzeiro*, A. Albuquerque*, F. Vacchi*, M. Szymczyk n, X. Sui n, R. Aalizadeh*, P. Ohe, N. Thomaidis*, N. Vinueza n, H. Freeman n

Contributors: G. Umbuzeiro*, A. Albuquerque*, F. Vacchi*, M. Szymczyk n, X. Sui n, R. Aalizadeh*, P. Ohe, N. Thomaidis*, N. Vinueza n, H. Freeman n

author keywords: Azo dyes; Anthraquinone dyes; ACO-SVM model; QSAR; MWDL; Daphnia
TL;DR: A good prediction capacity is observed for the 10 of the 15 tested dyes of the MWDL, but more dyes should be tested to extend the existing training set with similar dyes, to obtain a reliable prediction model that is applicable to the full MWDL. (via Semantic Scholar)
