Adapted from Table 17 in: Final report: Collaborative cohort mortality study of four chromate production facilities, 1958–1998 [53].

*Mean Exposure to Cr(VI) derived by dividing cumulative urinary chromium exposure by 0.77 (conversion factor for air concentration), and then dividing by 45 years (OSHA's working life assumption); see text for details.
