Bladder cancer incidence among workers exposed to o-toluidine aniline and nitrobenzene at a rubber chemical manufacturing plant

摘要

BackgroundAn earlier investigation found increased bladder cancer incidence among workers at a rubber chemical manufacturing plant that used o-toluidine, aniline and nitrobenzene. The cohort was expanded to include additional workers (n=1875) and updated through 2007 to assess bladder cancer with improved exposure characterisation.
