[Appearance of aromatic polycyclic hydrocarbons during construction of asphalt and tar road surfaces].
The dust was sampled using personal samplers and stationary aspirators. PAHs were determined by thin layer chromatography and spectrophotometry in the UV and Vis range. In the samples the concentrations of coal tar pitch volatiles (benzene extract) and phenanthrene, fluoranthene, pyrene, chrysene, tetraphene, benzo(a)pyrene, benzo(e)pyrene, perylene, 1,12 benzoperylene, indeno(1,2,3-cd) pyrene were determined. The qualitative analysis identified all these hydrocarbons but only fluoranthene, pyrene, chrysene, tetraphene and benzo(a)pyrene could be quantitatively determined. The benzene extract concentration exceeds the value of 0.2 mg/m3 in 50% of samples. Much higher results were obtained for tar-concrete (1.45-2.85 mg/m3) than for asphalt-concrete (0.14-0.71 mg/m3). Also the drivers are exposed to excess benzene extract concentrations (0.055-0.669 mg/m3). Laboratory workers were found to be exposed to high concentrations of PAH and several solvents.
