RT Journal Article SR Electronic T1 Cancer mortality in the asphalt industry: a ten year follow up of an occupational cohort. JF British Journal of Industrial Medicine JO Br J Ind Med FD BMJ Publishing Group Ltd SP 582 OP 585 DO 10.1136/oem.46.8.582 VO 46 IS 8 A1 Hansen, E S YR 1989 UL http://oem.bmj.com/content/46/8/582.abstract AB A historical cohort study was conducted to study the possible risk of cancer associated with exposure to asphalt. Altogether 1320 unskilled workers employed in the asphalt industry were followed up over a ten year period and compared with 43,024 unskilled men in terms of cause specific mortality. Both groups were identified from census records and followed up by an automatic record link that had been established previously between the census register, National Register, and Death Certificate Register. The cancer mortality was significantly increased in asphalt workers aged 45 or more, when five years' latency from enrolment into the study was allowed for (SMR for cancer: 159, 95% confidence interval: 106-228). Non-significant increases were seen for respiratory, bladder, and digestive cancers but a significant increase was seen for brain cancer (SMR = 500, 95% CI: 103-1461). Components of asphalt fumes may have been important to the observed association between risk of cancer and employment in the asphalt industry.
