Estimates of 40 year working lifetime excess mortality risk from lung cancer associated with secondhand smoke exposure among workers in bowling alleys, billiard halls, betting establishments, bars, and bingo parlours*
| Type of workplace | Weighted mean nicotine concentrations (μg/m3) and range† | Lung cancer mortality risk | Lower range of mortality risk | Upper range of mortality risk |
|---|---|---|---|---|
| *Mortality risk estimated using method developed by Repace and Lowrey12 for ambient nicotine values. For bingo workers, 2 hours of exposure twice a week are assumed, compared to a 40 hour work week for all other workers. Note that although the estimates are based on a working life (40 years) of exposure, the excess deaths could occur post-working life. | ||||
| †Weighted mean nicotine concentrations are from table 1. Range represents range of mean nicotine concentrations from individual studies. | ||||
