    This incident was the first major water contamination which brought public attention to MTBE. In general, these vapors should not be released directly into the air and therefore, should be appropriately treated. Broad agreement concerns are illustratated with a solid outlined circle icon. Appendix 2 of the document lists several current or recent research projects in these topic areas. GAC treatment technique pumps contaminated water through a bed of activated carbon to remove organic compounds.

    Researchers at EPA and other governmental organizations industry, and academic institutions are conducting studies to learn more about MTBE. Inthe city of Santa Monica learned that two of its drinking water wellfields, Charnock and Arcadia, were contaminated with MTBE at levels as high as ppb and 86 ppb respectively. Relationships between levels of volatile organic compounds in air and blood from the general population. Methyl Tertiary-Butyl Ether.

    A rapid method of total lipid extraction and purification. Environmental exposure of commuters in Mexico City to volatile organic compounds as assessed by blood concentrations, Toxicokinetics of methyl Tert-Butyl methyl ether book ether and its metabolites in humans after oral exposure. Refiners are required to reduce the emissions of volatile organic compounds, toxics, and nitrogen oxides by 27, 22, and 7 percent, respectively, compared to the conventional gasoline they produced in If your drinking water is supplied by a public water system, you can contact the system directly and ask whether they monitor for MTBE and what levels, if any, have been detected. Broad agreement: comes from industry data where a majority of data submitters agree the substance is a skin sensitiser.
