title: Lung cancer mortality in arsenic-exposed workers from a cadmium recovery plant.
abstract: BACKGROUND
  There is evidence that arsenic is a late-stage human lung carcinogen.
  
  
  OBJECTIVE
  To investigate lung cancer risks in a cohort of cadmium recovery workers in relation to period from ceasing exposure to arsenic.
  
  
  METHODS
  The mortality experience (1940-2001) of a cohort of 625 male workers from a US cadmium recovery plant was compared with expectations based on US national mortality rates.
  
  
  RESULTS
  There was a statistically significant (P < 0.05) negative trend in lung cancer standardized mortality ratios in relation to period from ceasing arsenic exposure.
  
  
  CONCLUSIONS
  The findings are consistent with the hypothesis that arsenic is a late-stage human carcinogen.
