Polycyclic aromatic hydrocarbon exposure and burden of outdoor workers in Budapest.

Polycyclic aromatic hydrocarbons exposure (PAHs: (benz[a]anthracene, benzo[a]pyrene, dibenz[a,h]anthracene, benzo[b]fluoranthene, benzo[k]fluoranthene, indeno[1,2,3-cd]-pyrene, fluoranthene, chrysene, pyrene) of policemen on street duty in downtown Budapest and workers repairing the road (asphalting) at a traffic junction and their excretion of PAH metabolites (1-hydroxypyrene, 3-hydroxybenz[a]anthracene, and 3-hydroxybenzo[a]pyrene) were determined. As controls, health-care workers were investigated. In addition PAH pollution of the air of a factory processing asphalt was also measured. The measurements were performed on air samples gained using personal samplers and from urine of end-shift samples using a high-performance liquid chromatography method. It was found that PAH pollution of the most crowded and busy center of Budapest was similar to that of several other cities in the world. PAH exposure of road builders was actually not higher than that of policemen; the slight difference resulted from diverging life-styles. PAH metabolite excretion of smoking health-care workers, road builders, or policemen significantly exceeded that of the nonsmokers. The PAH metabolite values of the three groups engaged in various activities did not show any difference. It was concluded that cancer-related risk due to PAH compounds in the case of policemen on street duty and road builders (asphalting) does not exceed significantly that of workers not exposed occupationally to PAHs in the ambient air, but that smoking is a decisive factor.[1]
