Promotion of liver and kidney carcinogenesis by ethyl tertiary-butyl ether (ETBE) in male Wistar rats
Tumor-promoting effects of ethyl tertiary-butyl ether (ETBE) were investigated in a 2-stage carcinogenesis bioassay with regard to hepatic and renal carcinogenesis in rats. Male 6-week-old Wistar rats were given drinking water containing N-ethyl-N-(2-hydroxyethyl)nitrosamine (EHEN), as an initiator, at a dose of 500 ppm for 2 weeks. Starting one week thereafter, the animals were administered ET...
متن کاملPredicted and experimental crystal structures of ethyl-tert-butyl ether.
Possible crystal structures of ethyl-tert-butyl ether (ETBE) were predicted by global lattice-energy minimizations using the force-field approach. 33 structures were found within an energy range of 2 kJmol(-1) above the global minimum. Low-temperature crystallization experiments were carried out at 80-160 K. The crystal structure was determined from X-ray powder data. ETBE crystallizes in C2/m,...
متن کاملEvaluation of Morphological and Mitochondrial Alterations of Mouse Fetus after Exposure to Methyl tert-butyl Ether
Although the biokinetics, metabolism, and chemical toxicity of methyl tert-butyl ether are well known, little attention was paid to the potential toxic effects of MTBE on reproduction and development in mammals. To evaluate the effects of MTBE on pregnant animals, two groups (control and test) of NMRI mice were chosen. In test group 500 and 1000 mg/Kg of it were administered intraperitonealy at...
متن کاملMethyl tert-butyl ether (MTBE) bioremediation studies
The massive production of methyl tert-butyl ether (MTBE), a primary constituent of reformulated gasoline, combined with its mobility, persistence and toxicity, makes it an important pollutant. It was considered recalcitrant until a few years ago, but recently MTBE biodegradation in aerobic conditions has been demonstrated with both mixed and pure cultures. Mixed cultures are generally the more ...
متن کاملRapid Biodegradation of Methyl tert-Butyl Ether (MTBE) by Pure Bacterial Cultures
Two pure bacterial strains capable of rapid degrading methyl tert–butyl ether (MTBE) were isolated from an industrial wastewater treatment plant, identified and characterized. These strains are able to grow on MTBE as the sole carbon and energy sources and completely mineralize it to the biomass and carbon dioxide. The strains were identified as Bacillus cereus and Klebsiella terrigena. Bot...
