Abstract

BACKGROUND:

Purpose of this study is to evaluate and to compare the excretion of urinary 1-hydroxypyrene (1-OHPu) in traffic policemen (TP) and drivers (D) of a large Italian city and to evaluate the existence and the degree of correlation between airborne exposure to 15 different polycyclic aromatic hydrocarbons (PAHs) and 1-OHPu levels in the examined population.

METHODS:

192 male workers, 115 TP and 77 D, were monitored for 1-HOPu. A subgroup of non-smoking workers (subgroup B: 59 TP and 15 D) was also examined and 15 environmental PAHs was monitored through the personal samplings for the measurement of the particulate phase.

RESULTS:

The 1-OHPu levels and the values of personal airborne exposure to PAHs were significantly higher among non-smoking TP than among non-smoking D (p < 0.05). In subgroup B the levels of environmental exposure to all the 15 PAHs measured in TP and only 6 of 15 PAHs measured in D were significantly correlated with the values of 1-OHPu (p < 0.05).

CONCLUSIONS:

Our results suggest that the use of 1-OHPu as an indicator of exposure to PAHs is reliable also for what concerns the study of the low-dose work-related exposure in urban outdoor workers.
