    The mortality and incidence of cancer was studied among 295 workers at a Swedish gas production company. All men employed for at least one year between 1965 and 1972 were included in the study. The follow up period for mortality was 1966 to 1986, and the incidence of cancer was followed up from 1966 to 1983. Expected numbers of deaths were based on local death rates among occupationally active men, the expected numbers of cancer were based on national statistics. The total mortality was increased, mainly due to an excess of deaths from circulatory diseases. The excess was larger after long follow up and after long employment periods. Two cases of cancer in the nose and nasal sinuses were found; there was no excess of lung cancer. Smoking habits were investigated for a subset of the cohort and did not differ from the average for men in large cities. The findings are discussed in relation to other studies of soot and combustion exposed workers.
