Mortality among rubber workers: VIII. Industrial products workers

Abstract

This report compares the mortality experience of 6,533 men employed in the industrial products division of a rubber manufacturing company with that of U.S. males and of other rubber workers. For most causes of death the mortality rates of industrial products workers were lower than those of U.S. males and similar to those of other rubber workers. Relative to other rubber workers, men in the industrial products division had a 50% excess of deaths from lymphoma, a 90% excess of deaths from multiple myeloma, and a 20% excess of deaths from bladder cancer during the study period. The excesses of lymphoma and multiple myeloma were strongest during recent follow-up in 1970–78 (observed/expected deaths: 10/4.3 for lymphoma; 10/4.4 for multiple myeloma), whereas bladder cancer mortality was not excessive during this calendar period.
