Abstract:
Asphalt is a mixture of bitumen, (its fumes contain about 1% of polycyclic aromatic hydrocarbons, PAH), and mineral matter. 18 Workers were investigated during road paving to assess PAH exposure by environmental air-monitoring (the 16 most relevant, according to the American Environmental Protection Agency, EPA) and biological monitoring (urinary 1-hydroxypyrene excretion). Our results show that PAH exposure in these workers is not higher than that observed in traffic policemen working in urban areas.
