Expert Panel on Air Quality Standards 321. The most recent quantitative risk evaluations of the workforce cancer data for arsenic yield pooled estimates of the unit risk of 1.43 x 10 -3 per µg/m 3 (Viren and Silvers, 1994) and 1.5 x 10 -3 per µg/m 3 (WHO, 2000). If one takes the figure from WHO (2000), then the EPAQS recommendation of 3 ng/m 3 equates to a lifetime risk of 4.5 in a million or about half of the one in 100,000 risk level discussed above as being of the order sometimes used in regulatory toxicology.
