A study was conducted to determine the health effects of exposure to methyl-tertiary-butyl-ether (1634044) (MTBE) in gasoline in Stamford, Connecticut. Subjects included 37 individuals who work near traffic or automobiles, and 14 commuters. The occupationally exposed group included workers inside car repair garages, gasoline service station attendants, and other workers who spent time in traffic. Subjects were given questionnaires relating to health and exposure. Venous blood samples from 30 workers and breathing zone air samples from 37 workers were taken and analyzed to determine levels of MTBE, benzene (71432), toluene (108883) and xylene (1330207). Odds ratios and confidence intervals were calculated for the collected data. Blood sample MTBE levels were variable, but were highest in service station employees. Commuters and workers who spent time in traffic exhibited similar levels of blood MTBE. Eleven subjects exhibited blood MTBE levels greater than 2.4 micrograms/liter, and these individuals reported the highest incidence of symptoms such as headache, eye irritation, dizziness, and nausea. Levels of MTBE in breathing zone air samples correlated with those for benzene. The authors conclude that the exposure information collected in this study will be helpful in assessing the health risks presented by MTBE exposure.
