Abstract: 

Based on human exposures to aerosols and vapours of bitumen in an experimental chamber the question of a possible percutaneous absorption could be answered. Commercial bitumen B 65 was used to generate the bitumen emissions. The system for air-sampling and -analytics separated as well the aerosols and vaporous parts of emissions as the PAH concentrations in each analytical matter. N = 10 mate non smoking probands equipped with and in addition two of them without a blower-supported breath mask were exposed during eight hours. The quantifying of the percutaneous and combined inhaled/percutaneous absorption, respectively, oriented by the biological monitoring of the PAH metabolites pyrene, chrysene, and phenonthrene in urine. The measured bitumen emissions ranged on the average at 20.4 mg/m(3) with a vapour content about 88 %. The two probands stressed by inhalation and percutaneous contact of the bitumen emissions showed PAH absorptions of about 57 % in the case of pyrene and chrysene, and ca. 50 % of phenonthrene.
