An estimate of the potential cancer hazard to populations exposed to airborne arsenic is given. Data analyzed are from occupational studies, estimates of ambient exposure and the number of cancer cases induced in the general or 'non-industrial' exposed populations. Using a linear model and data from three studies (Pinto et al. (1977), Ott et al. (1974), and Lee and Fraumeni (1969)), it is estimated that the increase in the lung cancer rate per increase of 1 micrograms/cu m of atmospheric arsenic was 9.4%, 17.0% and 3.3% respectively, with a geometric mean of these values calculated to be 8.1%. Using this value and data from a revised 1979 Stanford Research Institute arsenic exposure assessment, lifetime risk of respiratory cancer to those near cotton gins is calculated to be as high as 0.0134 and higher than 0.00001 for about 2.81 million people due to all sources of air arsenic exposure. Total atmospheric arsenic caused deaths due to respiratory cancer is estimated to be within a 95% confidence interval of 19.4 to 1.2 deaths annually.
