- Associations between various malignancies and work in the pulp and paper industry have been reported but mostly in analyses of mortality rather than incidence. We aimed to study cancer incidence by main mill pulping process, department and gender in a Swedish cohort of pulp and paper mill workers.The cohort (18,113 males and 2,292 females, enrolled from 1939 to 1999 with >1year of employment) was followed up for cancer incidence from 1958 to 2001. Information on the workers' department and employment was obtained from the mills' personnel files, and standardized incidence ratios (SIRs) were calculated using the Swedish population as reference.Overall cancer incidence, in total 2,488 cases, was not increased by work in any department. However, risks of pleural mesothelioma were increased among males employed in sulphate pulping (SIR, 8.38; 95% CI, 3.37-17) and maintenance (SIR, 6.35; 95% CI, 3.47-11), with no corresponding increase of lung cancer. Testicular cancer risks were increased among males employed in sulphate pulping (SIR, 4.14; 95% CI, 1.99-7.61) and sulphite pulping (SIR, 2.59; 95% CI, 0.95-5.64). Female paper production workers showed increased risk of skin tumours other than malignant melanoma (SIR, 2.92; 95% CI, 1.18-6.02).Incidence of pleural mesothelioma was increased in the cohort, showing that asbestos exposure still has severe health consequences, and highlighting the exigency of strict asbestos regulations and elimination. Testicular cancer was increased among pulping department workers. Shift work and endocrine disruptors could be of interest in this context.

- PURPOSE: To study cancer mortality among Swedish pulp and paper mill workers by main mill pulping process and department, and to present the Swedish part of an international exposure measurements database. METHODS: A cohort of 18,163 male and 2,290 female workers at four sulfate and four sulfite mills, enrolled from 1939 to 1999, was followed up for mortality during 1952-2001. Standardized mortality ratios (SMRs) relative to the general Swedish population were calculated. RESULTS: There were 1,340 malignant cases out of 5,898 deaths. Total cancer mortality was not increased in either sulfate or sulfite mill workers, or by gender. Lung cancer mortality was increased among female workers (SMR 1.70, 95% CI 1.04-2.63), especially in paper production, but not among male workers (SMR 0.91, 95% CI 0.79-1.04). Exposure to wood dust and sulfur dioxide frequently exceeded occupational exposure limits. CONCLUSIONS: Female paper production workers had an increased mortality from lung cancer.

- BACKGROUND: Occupational exposure to irritants is associated with chronic bronchitis. The aim of this study was to elucidate whether repeated peak exposures with respiratory symptoms, gassings, to sulphur dioxide (SO2) and other irritant gases could increase the risk of chronic bronchitis.METHODS: The study population comprised 3,060 Swedish pulp mill workers (84% males) from a cohort study, who completed a comprehensive questionnaire with items on chronic bronchitis symptoms, smoking habit, occupational history, and specific exposures, including gassings. 2,037 have worked in sulphite mills. Incidence rates and hazard ratios (HRs) for the observation period, 1970-2000, in relation to exposure and the frequency of repeated gassings to SO2 and other irritant gases were calculated.RESULTS: The incidence rate for chronic bronchitis among workers with repeated gassings was 3.5/1,000 person-years compared with 1.5/1,000 person-years among unexposed workers (HR 2.1, 95% confidence interval (CI) 1.4-3.1). The risk was even higher in the subgroup with frequent gassings (HR 3.2, 95% CI 2.0-5.2), particularly among never-smokers (HR 8.7, 95% CI 3.5-22).CONCLUSIONS: Repeated gassings to irritant gases increased the incidence of chronic bronchitis in our study population during and after work in pulp mills, supporting the hypothesis that occupational exposures to irritants negatively affect the airways. These results underscore the importance of preventive actions in this work environment.
