↵2-150 Excess risk estimates are for 1000 workers. For example, the excess lifetime risk of lung cancer for white men at 0.05 mg/m3 of silica is 19 deaths per 1000 workers.
↵2-151 Assuming that workers were exposed to a constant silica concentration for 45 years between the ages of 20 and 65, and accumulating annual risks up to age 85.
