MTBE is an aliphatic matter successfully removed from contaminated water by advanced oxidation process. Additionally, arsenic a toxic metalloid that detected in some supplies, such as Iran. Concerning the potential of aqueous solution, it expected its interference photocatalytic removal organic includes MTBE. Nevertheless, there lack observation this effect. In study, effect on using Fe2O3/MgO ...

One of the major drawbacks of IC engines is low efficiency and pollution resulting from incomplete combustion. In order to improve the emission properties and performance an oxygenated additive MTBE (Methyl tertiary butyl ether), is blended with gasoline. A four cylinder, 1817 cc engine was used for analysing both emission and performance characteristics. Tests were carried out with 100% pure g...

Your recent article panning methyl-tert-butyl ether use (EHP 102:913) was extremely misleading and focused on unpublished, and therefore not critically reviewed data, which is inconsistent with standards of scientific journals. Given the confusion caused by the article, you should provide more accurate information to your readers on why methyl-tert-butyl ether (MTBE) is in gasoline and how it i...

An aerobic fluidized bed reactor (FBR) was operated for the removal of methyl tert-butyl ether (MTBE) and benzene, toluene, ethylbenzene, and p-xylene (BTEX) from water. The reactor was seeded with a mixed culture adapted to MTBE. Granular activated carbon (GAC) was used as the biological attachment medium. Influent MTBE to the reactor was 7.8 mg/L MTBE, with a flow rate of 22.7 L/day, and an e...

AIM Methyl-tertiary-butyl ether (MTBE), a well-known gasoline oxygenate compound, is still used in several countries. Several studies investigated the effects of MTBE on the activity of phase II metabolism enzymes. There is no published data on the effect(s) of short-term exposure to MTBE on mRNA levels of antioxidant genes. Therefore, the present study was carried out. METHODS A total of 15 ...

The occurrence and concentration of the fuel additive methyl-tert-butyl ether (MTBE) were measured in dry weather runoff, municipal wastewater and industrial effluents, and coastal receiving waters in southern California. Combined, refineries and sewage treatment plants release approximately 214 kg day(-1) of MTBE into the marine environment, with Santa Monica Bay receiving most (98%) of this d...

A methyl tert-butyl ether (MTBE) / tert-butyl alcohol (TBA) plume originating from a gasoline spill in late 1994 at Vandenberg Air Force Base (VAFB) persisted for over 15 years within 200 feet of the original spill source. The plume persisted until 2010 despite excavation of the tanks and piping within months after the spill and excavations of additional contaminated sediments from the source a...

In the 1980s and 1990s, methyl tertiary-butyl ether (“MTBE”) became the petroleum industry’s gasoline additive of choice to replace tetra-ethyl lead. MTBE fuel blends were viewed as an environmental boon; MTBE signiacantly reduces emissions of smog-producing air pollutants and can be produced relatively cheaply. Yet by the end of the 1990s, MTBE had leaked from tens of thousands of underground ...

Methyl-tert-butyl ether (MTBE), a fuel oxygenate that is added to gasoline, commonly contaminates aquatic systems, many of which are already contaminated with pesticides. The toxic effects (EC(50) value) of several pure pesticides (Diuron, Linuron, Dichlofluanid, Sea nine, Irgarol and tributyltin (TBT)) were measured and compared with the EC(50) value of the pesticide mixed with MTBE, using the...
