[Evaluation of occupational exposure to aromatic polycyclic hydrocarbons in bituminous pulp plants].
A method was developed for isolation of aromatic polycyclic hydrocarbons (APH) from atmospheric air. Air samples were filtered through Whatman GF/C filter papers, subsequently extracted with benzene. Aromatic polycyclic hydrocarbons were isolated from the extract, purified by column chromatography on aluminium oxide and determined by gas chromatography. This method was applied to determine qualitatively and quantitatively: naphthalene, anthracene, pyrene, perilene, biphenyl, fluoranthene, phenanthrene, benzo(a)pyrene, dibenzo(a,c)anthracene, dibenzo(g,h)anthracene, 11H-benzo(a)fluorane, 11H-benzo(b)fliorene, benzo(g,h,i)perylene, benzo(a)anthracene, chrysene, indene and durene. Professional exposure in years 1977-1989 was comparatively assessed using the evaluation criterion for APH expressed as the benzene fraction (0.2 mg/m3--USA standard) and as benzo(a)pyrene (0.00015 mg/m3--USSR standard). According to the accepted standards, working conditions in the examined plants entail a risk for the employees. Comparison of the results obtained before and after reconditioning of the machinery suggests the need for further modernization aimed at application of new technical solutions allowing for limitation of pollutant emission to air.
