Exposure distribution of urinary metabolites of polycyclic aromatic hydrocarbons corrected for urinary creatinine.
| PAH metabolites | Range of PAH per gram of creatinine (μg/g cratinine) | Geometric mean (95% CI) | Quartile 1 | Quartile 2 | Quartile 3 | Quartile 4 |
| 1-Hydroxynaphthalene | 0.86-15.85 | 15.86-34.17 | 34.18-81.94 | 81.95-1776.6 | 36.3(31.4-42) | 2-Hydroxynaphthalene | 0.62-13.5 | 13.5-27.6 | 27.6-66.95 | 66.96-763.96 | 29.4(25.6-33.8) | NAP metabolites | 5.12-31.4 | 31.5-66.7 | 66.8-158.5 | 158.6-2181 | 72.26(63.3-82.5) |
