摘要

The objective of this study was to investigate the concentration level and distribution of polycyclic aromatic hydrocarbons (PAHs) in surface water of the Raba River; the largest Danube tributary in Hungary. A total of 54 water samples were collected in the period of 2008-2011 and analysed for PAHs by gas chromatography-mass spectrometry (GC/MS) method. The total PAH concentrations (sum of the concentrations of 17 individual PAH compounds) ranged from 41 to 437 ng/L with the mean value of 111 ± 69.4 ng/L. Phenanthrene and naphthalene were the dominant species in the surface water. Using TEF approaches on the mean concentration PAH data, benzo[a]pyrene and dibenz[ah]anthracene contributed the highest carcinogenic exposure equivalent. A selected number of concentration ratios of specific PAH compounds were calculated to evaluate the possible sources of PAH contamination. The ratios reflected a pattern of pyrogenic input as a major source of PAHs. The comparison of the total PAH concentrations observed for Raba River with other surface waters of the world confirmed that the Raba River could not be regarded as a contaminated river according to the levels of PAHs.
