Title Mortality from leukemia and other diseases among workers at a petroleum refinery
Bibliographic information Feb. 1989, Vol.31, No.2, p.106-111. 23 ref.
Abstract This study evaluates the mortality experience of 9484 white men who worked at a petroleum refinery. The number of deaths among these men during the period 1940 through 1984 was compared with the number expected on the basis of the mortality rates of US white men. Overall, there were 2,874 observed compared with 3,568 expected deaths. Mortality rates for most major cause of death categories and most cancers were also lower than expected. However, there was a statistically significant 50% excess of leukaemia deaths. Lymphocytic leukaemia was increased both among men hired before 1940 and among men hired in 1940 or later. In contrast, myelocytic leukaemia was increased only among men hired in 1940 or later. This may be due to increased use of benzene in some refinery streams. The presence of an excess of lymphocytic leukaemia, but not myelocytic leukaemia, among men hired before 1940 suggests that some factor other than benzene was responsible for the former condition.
