Mutagenicity tests of fabric-finishing agents in Salmonella typhimurium: fiber-reactive wool dyes and cotton flame retardants

Environmental Mutagenesis

Abstract

Thirty-nine fabric-finishing agents were tested for mutagenic activity in Salmonella typhimurium. Twenty-four fiber-reactive wool dyes and three acid dyes (not fiber-reactive) were screened by spot tests in strains TA100, TA98, TA1535, and TA1537. Among these dyes, seven bromoacrylamide dyes and one vinyl sulfone dye were mutagenic. Additionally, one of the three acid dyes was mutagenic in spot tests. The mutagenicity of the acid dye was due to an impurity or breakdown product rather than to the dye itself; the origin of the activities of the other dyes is unknown. No mutagenicity was observed among five chlorotriazine or four sulfonyl-ethane sulfonic acid dyes. Eight phosphorus-containing flame retardants (phosphonium, phosphine, phosphine oxide, and phosphonic acid derivatives) and methyl-N-methylolcarbamate, which is employed to obtain a flame-retardant finish on cotton, were tested for mutagenicity in strains TA100, TA98, TA1535, and TA1537, using quantitative incorporation assays. All were nonmutagenic. Two of three bromoalkyl-substituted triazine flame retardants were mutagenic in strains TA100 and TA1535. It is unknown whether this activity is due to impurities or to the parent compound. The flame retardants tested were ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
