Title Occupational exposure to bitumen during road paving
Bibliographic information Mar.-Apr. 2002, Vol.63, No.2, p.156-165. Illus. 53 ref.
Abstract The exposure of workers to total particulates, bitumen fumes, semi-volatile organic compounds (SVOCs), polycyclic aromatic hydrocarbons (PAHs), low-molecular-weight amines, styrene, and 1,3-butadiene was studied at 13 road paving sites where 11 different asphalt mixtures were laid. 1-hydroxypyrene was analysed in the workers' pre- and post-shift urine samples. Mean concentrations of total particulates, bitumen fumes, SVOCs, and PAHs in the breathing zone of road pavers were 0.6mg/m3, 0.29mg/m3, 5.6 mg/m3, and 5.03µg/m3, respectively. Over 90% of air impurities were in the vapour phase. Exposure to PAHs during road paving operations was more than 10-fold higher than was the exposure of a traffic controller (0.34µg/m3) caused by automobile exhausts from background traffic. Concentrations of amines, impurities from polymer-modified bitumens, styrene, and 1,3-butadiene were below detection limits. Urinary 1- hydroxypyrene concentrations were higher among road pavers than among office workers serving as referents.
