Abstract
The mortality experience of workers in the phosphate fertilizer industry (SIC-2874) was evaluated. A retrospective cohort study was conducted to determine if workers had an increased risk of lung cancer. A total of 3,160 workers were investigated. The vital status of study subjects was determined from data provided by the Social Security Administration, the Internal Revenue Service, and the Florida Department of Motor Vehicles, and death certificates. Company records were examined in order to obtain a demographic file. Life table analysis was performed and standard mortality ratios (SMRs) were calculated. None of the cause specific SMRs were significantly elevated. For white males no trends associated with lung cancer were evident for either duration of employment or length of follow up. For black males, the SMRs appeared to increase with both duration of employment and length of follow up, although there were only a few deaths in each of these categories. The authors conclude that there was a statistically significant excess in lung cancer mortality among black males in the longest duration of employment and follow up categories. Although the small number of deaths involved preclude generalizing from this result, the finding is suggestive of a possible association with occupational exposure.
