Aim of this work was the assessment of exposure to polycyclic aromatic hydrocarbons (PAHs) by urinary 1-hydroxypyrene (1-OHPyr) in asphalt workers. Median levels of 1-OHPyr resulted higher in asphalt workers than in controls (184 vs. < 20 ng/L, p < 0.001). The determinants of exposure of 1-OHPyr resulted smoking habit, the number of consecutive days at work and the job task; 1-OHPyr was also associated to urinary creatinine. End of work week 1-OHPyr is suggested as an useful indicator of occupational exposure to PAHs in bitumen fumes.
