A retrospective cohort mortality study on workers of two thermoelectric power plants: fourteen-year follow-up results.
Although many studies have been performed to evaluate the environmental impact of coal energy production, few studies are available on the health risk for the people working in coal power plants. A retrospective cohort study was performed on the workers of two power plants near Venice (which use coal since 1968) in order to test the association between exposure to coal dust and ashes and mortality for all causes, all cancers, and respiratory and digestive cancer. One thousand three hundred seven male workers were followed up from 1968 to 1984. During this period 41 workers died; causes of death were collected from the local Mortality Registers and/or from the Hospital Records. The observed mortality of the study cohort was compared with the mortality expected from the Italian death rates in the same period. No Standardized Mortality Ratio (SMR) was found in excess in the working cohort with respect to the standard population for any of the investigated effects.
