The main objectives of the research were to estimate the relationship between
the gas-particle partition coefficient, Kp, and the octanol-air partition
coefficient, KOA, of polycyclic aromatic hydrocarbons, PAHs, and
polychlorinated biphenyls, PCBs, at industrial and urban sites in the
Vojvodina region, to compare the obtained slopes and intercepts of the log
vs. log KOA relations with the results of regression analyses reported in
previous studies and to assess the consistency between the particle-bound
fractions predicted by the KOA absorption model and the results obtained
within field measurements. Fairly good log KP - log KOA correlations, with an
average value of the correlation coefficients of 0.70, indicate that the
partition coefficient KOA can be used as a prediction parameter of the
gas-particle partitioning processes for both classes of compounds. The
results of modelling the atmospheric distribution of PAHs using the KOA
absorption model showed inconsistencies between the measured and predicted
values of the particle-bound fraction, ?, of 1-2 orders of magnitude, while
significantly higher discrepancies for PAHs in the Nap-Ace range were found.
A similar variability of the measured/modelled ? values was obtained using
the Junge-Pankow adsorption model, indicating the presence of particles
enriched with PAHs. The conducted research showed that the KOA-based approach
was less suitable for predicting the gas-particle partitioning of PCBs in
urban and industrial sites, compared to the Junge-Pankow model.
