In response to a request, an evaluation was made of cancer incidence and possible hazardous conditions at the Chevron U.S.A. Laboratory. The laboratory performs product analyses and tests on environmental samples to satisfy Environmental Protection Agency requirements. Airborne concentrations of toluene, xylene, n-heptane, and n-hexane were all below the recommended OSHA levels. Five breathing-zone samples and one general area air sample exceeded the NIOSH 0.1 part per million recommended exposure limit for benzene. Some laboratory hoods did not meet minimum requirements to maintain contaminant concentrations below exposure limits. Deaths due to all malignant neoplasms were not found to be elevated. There was a statistically significant excess of rectal cancer and three deaths due to hematopoietic disorders.
