β¦ Synopsis
The proportions of male lung cancers due to occupational exposure and, respectively, to cigarette smoking in a highly industrialized area of Northern Italy were esti- mated in a population-based case-control study in 1976-9.
Two hundred and four out of the 2 I I lung cancer cases and 351 controls sampled from the source population were questioned about their occupational and smoking histories. On the basis of the occupational history each subject was classified as probably exposed (+), possibly exposed (I), or unexposed (-) to one or more of the chemicals known to be carcinogenic for the human lung, namely asbestos, po!ycyclic aromatic hydrocarbons, arsenic, nickel and chromium compounds, BCME, CMME and vinyl chloride. Upon stratification by cigarette smoking, contrasting the occupationally exposed subjects, whether certainly or uncertainly defined, with the unexposed ones, the RR for lung cancer was 2. I and the occupational etiologic fraction was 0.33 (95 % confidence interval 0.19-0.47). The 4~~ whom reprint requests should be sent.

The importance of occupation held longest as a risk factor for lung cancer was examined in a prospective study in Norway of 11,995 men, among whom 125 cases occurred in a follow-up from 1966 through 1978. Based on information about occupation held longest, the respondents were classified into 3 gro
There is no doubt about the leukemogenic effect of benzene in man. The evidence is as follows: (1) The incidence of leukemia in shoeworkers exposed to benzene in a period of 8 years in Istanbul was 13.6/100,000, which is significantly higher than that for leukemia in the general population.

## Abstract An increased risk of lung cancer has been reported for butchers and meat workers in several cohort studies, although confounding from tobacco smoking could not be ruled out in any of these studies. These exposures, as well as a potential risk associated with contact with live animals, a
