Servers’ and patrons’ risk of lung cancer death (LCD) due to exposure to secondhand smoke in restaurants and bars in Minnesota
| Patrons | ||||
|---|---|---|---|---|
| Servers | Smoking venues/sections | Non-smoking sections | ||
| Weighted SHS-PM2.5 levels, mean (95% CI), µg/m3 | 78 (64 to 91) | 134 (110 to 158) | 30 (22 to 38) | |
| Dose response according to Repace and Lowrey16 | 5×10−5 per year for exposure to 1 mg per day | |||
| Breathing rates, m3/h | 1.6 | 1.0 | 1.0 | |
| Average hours per day exposed to SHS, h/day | 4 | 1.4 | 1.4 | |
| Days per week exposed to SHS, day/week | 5 | 1 | 1 | |
| Number of years exposed to SHS, years | 45 | 60 | 60 | |
| Lifetime attributable risk of LCD (95% CI), 10−6 | 802 (658 to 936) | 80 (66 to 95) | 18 (13 to 23) | |
The 95% CIs presented here indicate only the variance of the weighted SHS-PM2.5 levels during peak patronage times; uncertainties from other sources are not integrated.
SHS, secondhand smoke; PM2.5, fine particulate matter.
