The potential for immunotoxicological effects of ethyl tertiary butyl ether (ETBE, CAS RN 637-92-3) was studied in young adult female Crl:CD(SD) rats following subchronic oral exposures. Rats were exposed by gavage once daily for 28 consecutive days to 0, 250

Chemosphere, 76(5), 672-676 (2009-05-30)
The use of ETBE (ethyl-tert-butylether) as gasoline additive has recently grown rapidly. Contamination of aquatic systems is well documented for MTBE (methyl-tert-butylether), but less for other gasoline additives. Due to their mobility they may easily reach drinking water collection areas.

The Journal of pharmacy and pharmacology, 61(9), 1243-1248 (2009-08-26)
The effect of ethyl tertiary-butyl ether (ETBE), which is widely used as a fuel oxygenate commonly produced from bioethanol, on immunoglobulin (Ig)E-dependent mast cell activation was investigated. The rat mast cell line RBL2H3 sensitised with monoclonal anti-ovalbumin IgE was challenged

Ethyl tert-butyl ether (ETBE) was detected at high concentration (300mgL(-1)) in the groundwater below a gas-station. No significant carbon neither hydrogen isotopic fractionation of ETBE was detected along the plume. ETBE and BTEX biodegradation capacities of the indigenous microflora Pz1-ETBE

The carcinogenicity of ethyl tertiary-butyl ether (ETBE) was examined by oral administration using F344/DuCrlCrlj rats. Groups of 50 male and 50 female rats were given drinking water containing ETBE at doses of 0, 625, 2,500 or 10,000 ppm (w/w) for
