||Updated mortality study of workers at a petroleum refinery in Torrance, California, from 1959 to 1997
||Dec. 2001, Vol.43, No.12, p.1089-1102. 15 ref.
||This cohort study involved 3328 workers employed at a refinery for at least one year between 1959 and 1997, with an observation period from 1960 to 1997. Mortality data were analysed in terms of cause-specific standardized mortality ratios with expected deaths based on US national data. The overall mortality of the cohort was significantly lower than expected. Overall cancer mortality was also lower than expected, with significant mortality deficits being observed for certain specific sites. For other diseases, no significant increases were observed, with specific mortality deficits for ischaemic heart disease, chronic endocardial disease and other myocardial insufficiencies, all other heart disease, and influenza and pneumonia. Detailed analysis by length of employment did not reveal any significant mortality excess or upward trend. Analyses of male employees by job classification (process and maintenance) showed significantly elevated mortality from cirrhosis of the liver and suicide among maintenance workers.
