Abstract

The cancer slope factor for the bladder and lung cancer mortality by well water arsenic concentration in the southwest Taiwan Blackfoot Disease shows a discontinuity at levels above and below 100-200 ppb in a reiterative truncated Poisson regression analysis. This finding is independent of the summary exposure metric used. The observed cancer pattern may reflect a different process at low arsenic exposures, the presence of a second carcinogenic exposure, or errors in the data set that have not been resolved.
