A retrospective study by the Minnesota Department of Health of the occurrence of leukemia and other cancers in highway maintenance workers (HMW) in Minnesota was presented. These workers have been exposed to possible carcinogens such as asphalt (8052424) and tars, diesel fuels and exhausts, gasoline, polynuclear aromatic hydrocarbons, herbicides, benzene (71432), and lead (7439921). Subjects were classified as either urban or rural workers. Variables in the study were age at death, year of death, age and year subject started working, years worked, and time from start of work until death. Cancer was broken into twenty three categories. The cancer incidences for HMW were compared with statistics for the general population. Of the 4849 white male workers who had worked one or more years during the period of 1945 to 1984, there were 1530 deaths. Cancer rates in general were significantly reduced for HMW as compared to the general population. There was also a significant reduction in lung cancer which is inconsistent with HMW exposure. There were elevations in leukemia cases particularly among workers with 30 to 39 years of experience. Urologic cancer mortality was also significantly elevated. The authors do not correlate the cancer data to specific work exposures.
