Mutagenicity and metabolism studies on 12 thiuram and dithiocarbamate compounds used as accelerators in the Swedish rubber industry. 1979

A Hedenstedt, and U Rannug, and C Ramel, and C A Wachtmeister

12 thiuram and dithiocarbamate compounds used in the rubber industry as accelerators, and to some extent as sources of sulfur, were tested, as well as carbon disulfide, a metabolite found in vivo after dithiocarbamate treatment, for mutagenicity in Salmonella typhimurium. A mutagenic effect on the base-substitution-sensitive strains TA1535 and TA100 was found for 7 compounds. The most potent directly acting mutagens were: tetramethylthiuram disulfide (TMTD), zinc dimethyldithiocarbamate (ziram), cadmium diethyldithiocarbamate and zinc diethyldithiocarbamate. Tetraethylthiuram disulfide (TETD), also known as Antabus, and carbon disulfide were non-mutagenic. The relatively low direct mutagenic effect of tetramethylthiuram monosulfide (TMTM) was enhanced in the presence of a metabolizing system (S9 mix). A hypothesis is given regarding the activation process of the monosulfide TMTM.

D009154	Mutation	Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.	Mutations
D002246	Carbon Disulfide	A colorless, flammable, poisonous liquid, CS2. It is used as a solvent, and is a counterirritant and has local anesthetic properties but is not used as such. It is highly toxic with pronounced CNS, hematologic, and dermatologic effects.	Disulfide, Carbon
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012408	Rubber	A high-molecular-weight polymeric elastomer derived from the milk juice (LATEX) of HEVEA brasiliensis and other trees and plants. It is a substance that can be stretched at room temperature to at least twice its original length and after releasing the stress, retract rapidly, and recover its original dimensions fully.
