Separations were carried out using isocratic elution with the hexane methyl tert-butyl ether (MTBE) mobile phase, with the MTBE content varying from 0 to 30%% (v/ v).
The reaction mixture was precipitated with MTBE followed by several washes of MTBE and drying of the crude peptide under vacuum.
Under the proposed agreement, contributions from MTBE manufacturers like Lyondell Chemical and Exxon Mobil, independent importers of MTBE-containing gasoline and gasoline station owners would make up the $2 billion private portion of the fund.
* $800 million to help large refineries recover from the phase-out of the gasoline additive MTBE, a groundwater contaminant.
The initial MTBE concentration did not affect the lag period but the biodegradation rate increased with the initial MTBE concentration, indicating that there was no inhibition of MTBE biodegradation related to MTBE concentration up to 1.2 mg/L.
Thus, the present study, although showing increased total symptoms among SRSs when exposed to gasoline with 15% MTBE, did not support a dose-response relationship for MTBE exposure nor the symptom specificity associated with MTBE in epidemiologic studies.
It doesn't take much MTBE to impart a foul odor to drinking water, but still there is scant evidence that tiny amounts of MTBE pose a health risk.
Another substance, MTBE, was also picked up.
The MTBE provision was a priority of Representative Tom DeLay, the House majority leader, and other lawmakers from Louisiana and Texas, where MTBE is produced.
Very little is known about ingesting MTBE, but animals have developed cancers after inhaling large quantities.
The suits seek compensation for cleaning up the additive methyl tert-butyl ether, known as MTBE.
