Abstract Benzene is a natural constituent of crude oil and natural gas (0.1-3.0% by volume). Materials that are refined from crude oil and natural gas contain some residual benzene. In this study, historical samples of airborne benzene collected from 1977-2005 at the docks of a large refinery and petrochemical plant in the United States were evaluated. Workers were categorized into 11 job titles for which benzene concentrations were assessed. Approximately 800 personal air samples were analyzed. Findings are discussed. Samples for specific job categories showed that concentrations have decreased over the past 30 years. Recognizing the potential for benzene exposure, this facility has required workers to use respiratory protective equipment during selected tasks and activities; thus, the concentrations measured were likely to be greater than those that the employees actually experienced.
