Abstract:
The potential for percutaneous absorption of aerosols and vapors of bitumen was investigated in human beings using an experimental chamber. Commercial bitumen B 65 was used to generate the bitumen emissions. The system used for air sampling and analysis permitted the separate evaluation of aerosols and vapors as well as the polycyclic aromatic hydrocarbon ( PAH) concentrations and contents, respectively. n = 10 male nonsmokers were exposed for 8 h with and two of them in addition without a powered air purifying respirator ( PAPR). Quantification of the percutaneous and combined inhaled/ percutaneous absorption was related to the biological monitoring of the PAH metabolites pyrene, chrysene, and phenanthrene in urine. The bitumen emissions in chamber were determined to be 20.4 mg/ m(3) with a vapor content of about 88%. Two subjects stressed by inhalation and percutaneous contact with bitumen showed PAH absorption values of approximately 57% for pyrene and chrysene and about 50% for phenanthrene.
