It is not a high production volume chemical but is listed in the Toxic Substances Control Act Inventory. It is utilized in a variety of other applications including synthesizing polymers and heavy metal and basic salts; in cross linking halogenated polymers; as an additive in lubricating oils and greases; in electrode compositions; as an intermediate or starting material for pharmaceuticals and dyes; as a chelating agent in the analysis of metals; in purifying and treating waste; and as a biocide. An estimated 1,602 employees were potentially exposed to DMTD in the workplace between 1981 and 1983. Seven cases of allergic sensitization were reported at one manufacturing plant. It can cause chemical conjunctivitis, and eye, skin, respiratory tract, and gastrointestinal irritation in man. It caused moderate acute skin and eye irritation in rabbits. Daily oral doses of an unspecified DMTD reaction product given to rats for 28 days induced hepatocyte hypertrophy in males and females; females also had increased basophilia of the cortical tubules and increased liver and kidney weights. DMTD was not cytotoxic in rat tracheal epithelial cell cultures. It was chemopreventive in some in vivo tests (e.g., inhibited lung adenocarcinomas induced by N,N-diethylnitrosamine in hamsters and the carcinogenic activity of benzo[a]pyrene and N-butyl, N-(4-hydroxybutyl)nitrosamine in mice). It was also anticarcinogenic in several in vitro studies (e.g., for tyrosine kinase inhibition in human leukemic cells, primary human fibroblast inhibition, and for induction of reduced glutathione in buffalo rat liver cells). i" |
