Title Mortality among hard metal workers
Original title Dödsorsaker hos hårdmetallarbetare [in Swedish]

Abstract Mortality was studied in 3,163 male Swedish workers with at least 1yr of occupational exposure to cobalt at a hard metal manufacturing plant. The number of subjects who died from different causes between 1951 and 1982 was compared to expected figures based on national statistics. 292 subjects died before the age of 80 compared to 303.6 expected deaths. Subjects with employment of short duration showed a considerable excess risk, due in part to alcohol-related causes of mortality. Seven subjects with employment of long duration died of lung cancer; the expected figure was 2.5. Sixteen men with high exposure to cobalt and employment of long duration died because of ischaemic heart disease (9.4 expected). There was also an elevated risk of death due to pulmonary fibrosis. Exposure has decreased in recent decades but the results suggest that occupational exposure to cobalt should be kept to the lowest possible level so as to minimise risks.
