Title Non-Hodgkin's lymphoma and exposure to benzene in a multinational cohort of more then 308,000 petroleum workers, 1937 to 1996

Abstract To determine the risk of non-Hodgkin's lymphoma (NHL) in petroleum workers, cohorts of petroleum workers in the United States, the United Kingdom, Canada, Australia, Italy, and Finland were identified. The combined multinational cohort consisted of more than 308,000 workers, and the observation period covered an interval of 60 years from 1937 to 1996. A total of 506 NHL deaths were observed, compared with 561.68 expected. Analyses of Standardized Mortality Ratios (SMRs) were performed by type of facility and industrial process. SMRs were 0.96 for US refinery workers, 1.12 for non-US refinery workers, 0.64 for gasoline distribution workers, and 0.68 for crude oil workers. Results from individual studies, as well as from the pooled analysis, indicated that petroleum workers were not at an increased risk of NHL as a result of their exposure to benzene or benzene-containing petroleum products in their work environment.
