An industry-wide mortality study on the association between lung cancer and occupational exposure to cobalt and tungsten carbide was carried out in the French hard-metal industry. This case-control study was nested in the historical cohort of workers ever employed in this industry's 10 facilities, most of which are located in eastern France. Workers were(More)
In French Health Examination Centres, populations in deprived situation were usually defined by administrative criteria The aim of the study was to investigate whether EPICES, a new individual index of deprivation, was more strongly related to health status than an administrative classification. The EPICES score was calculated on the basis of 11 weighted(More)
OBJECTIVES To study the mortality from lung cancer from exposures to hard metal dust at an industrial site producing hard metals--pseudoalloys of cobalt and tungsten carbide--and other metallurgical products many of which contain cobalt. METHODS A historical cohort was set up of all subjects who had worked for at least 3 months on the site since its(More)
OBJECTIVES The mortality of workers involved in the production of stainless and alloyed steel from 1968 to 1992 was studied, in order to investigate the risk of lung cancer due to exposure to metals, i.e. iron oxides, chromium and/or nickel compounds. METHODS The study design was a historical cohort mortality study and a nested case-control study(More)
The mortality between 1950 and 1976 of 6455 French aluminium plant workers was analysed in order to assess occupational risks (especially lung cancer) associated with electrolysis, particularly with the Söderberg process. Mortality from all causes (SMR = 0.85), was lower in this cohort than in the French male population ('healthy worker effect'), and cancer(More)
OBJECTIVE A mortality study on the association between lung cancer and occupational exposure to polycyclic aromatic hydrocarbons (PAHs) was carried out in a French aluminium reduction plant. This study updated a previous mortality study. METHOD The historical cohort included every male worker who had been employed in the plant for at least 1 year between(More)
From 1975 to 1984, the incidence of cancer was determined among workers employed in a French man-made mineral fiber (MMMF) production plant. The cohort, including 1 374 fully active or retired men, represented 12 793 person-years. Forty-one patients had cancer, 19 of which were in the upper respiratory and alimentary tract and five of which were lung(More)
The follow-up of a cohort of workers employed in an electrochemical plant producing cobalt and sodium, previously studied from 1950-1980, has been extended from 1981-1988. The standardized mortality ratio (SMR) for all causes of death was 0.85 (95% confidence interval [CI] = 0.76-0.95, 309 observed) for the whole cohort, and 0.95 (95% CI = 0.83-1.08, 247(More)
A cohort mortality study was carried out among workers of a plant producing hard metals using cobalt as a binder. This study was aimed at assessing possible lung cancer risks in relation with cobalt exposure. Seven hundred nine male workers with at least 1 year of employment were included in the cohort and followed for mortality from 1956 to 1989. Job(More)
A historical mortality study of a cohort of employees of a gold mining and refining company was carried out in Salsigne, France. A major goal of the study was to investigate the relationship between lung cancer mortality and exposure to arsenic, radon, silica, and other contaminants of the working environment. A twofold excess of lung cancer was found both(More)
