Geometric means (and geometric standard deviations) of urinary analytes before and after 6 h of work by self-reported smoking status
| Levels of urinary analytes (ng/l) | Before work (n=18) | After work (n=17) | ||
| Non-smokers (n=10) | Smokers (n=8) | Non-smokers (n=9) | Smokers (n=8) | |
| 1-OH-naphthalene | 672 (4) | 1604 (3) | 1978 (2)* | 3395 (2)* |
| 2-OH-naphthalene | 1808 (2) | 4316 (2)* | 2670 (2) | 6186 (2)* ‡ |
| 9-OH-phenanthrene | 265 (4) | 846 (2)* | 713 (3)* | 1572 (2)* |
| 2-OH-fluorene | 358 (3) | 1495 (2)* | 925 (3)* | 2724 (2)* ‡ |
| 1-OH-pyrene | 213 (3) | 692 (2)* | 498 (2)* | 1002 (2)* |
| 8-OHd-guanosine (μg/l) | 8 (6) | 12 (2) | 29 (2)* | 59 (2)* † |
Using multiple comparisons: *p<0.05 when compared with non-smokers before work; †p<0.05 when compared with smokers before work; ‡p<0.05 when compared with non-smokers after work.
