Mortality among members of two medium-sized trade unions, the union of carpenters/cabinet makers and the union of bricklayers was studied to investigate if the greater exposure to dust and organic solvents of the carpenters/cabinet makers caused any increase in mortality from lung diseases. The study did not reveal any significant differences in mortality regarding any category of diagnosis except suicide, when the analysis was based on the main diagnosis recorded on the death certificate.
