Environmental and medical evaluations were conducted on May 2, 1978 at the quality control laboratory of the Amoco Texas Refining Company (SIC-2911), in Texas City, Texas in response to a request from an authorized employee representative of the Oil, Chemical and Atomic Workers International Union to determine possible toxic exposure to benzene (71432) among approximately 60 employees. Personal and general air samples were analyzed for benzene, toluene (108883), and xylene (1330207) content. Medical interviews were conducted and relevant medical records of nine laboratory workers were reviewed. Air sample analysis revealed no benzene, toluene, or xylene concentrations above applicable OSHA standards (30, 750, and 435 milligrams per cubic meter, 8 hour time weighted average, respectively). The authors conclude that there was no medical evidence of benzene toxicity in this work force. Recommendations resulting from the evaluation include keeping toxic chemical exposure to a minimum, instructing workers in continued adherence to good hygiene and health practices, and medically observing those workers who show persistent, though non-work related, blood abnormalities.
