A followup study was conducted on the mortality rates of a group of lead (7439921) smelter workers which had been studied from 1977 through 1988. The average airborne lead concentration to which these workers had been exposed was 3.1mg/m3 and the blood levels averaged 56.3 micrograms/100 milliliters in 1976. Arsenic (7440382) exposures in this cohort were relatively low. An excess amount of kidney cancer was identified in the group, particularly at the higher exposure levels. A previously elevated rate of chronic renal disease was lessened somewhat in this followup period. Deaths from accidents and nonmalignant respiratory disease were significantly increased. When comparing the findings based on length of exposure, chronic renal disease was elevated among those with the longest exposure histories. No specific trend was noted for kidney cancer with regard either to duration of exposure or time since first exposure.
