The mortality rate of workers at a phosphate (14265442) fertilizer production facility (SIC-5191) was studied with special emphasis on deaths from lung cancer. A total of 3,199 workers employed at such a facility was investigated from date of employment to date of death or to December, 1977. Death certificates were examined to determine cause of death, and standardized mortality ratios were calculated according to race and sex. Overall, no statistically significant elevations in cause specific mortality were observed for the entire study population. When the analysis was stratified by duration of employment, a statistically significant excess in lung cancer mortality was observed among workers with more than 10 years of employment. A slight excess of lung cancer incidence was also found among black male workers. The authors conclude that other investigations should be held in facilities with similar exposures in order to clarify whether an occupationally related lung cancer excess truly exists.
