Concentrations of 16 polycyclic aromatic hydrocarbons (PAHs) in soil, moss and reindeer dung collected at Ny-Ålesund of the Arctic were measured to investigate their accumulation trends and distribution in the three compartments. Compared with the other regions, the proportions of 2 + 3 ring PAHs to the total PAHs were higher, whereas the proportions of 5 + 6 ring PAHs were lower in the three compartments at Ny-Ålesund. Significant log/log-linear relationship was observed between the sub-cooled liquid vapor pressure and the soil/moss quotient (Q
SM ). The relation was similar to the relationship between the gas/particle partition coefficient (KP ) and of PAHs, implying QSM would be a “mirror image” of KP . Excellent log/log-linear relationships were observed between QSM and KOA as well as between the moss/dung quotient (QMD ) and KOW . The results presented here indicate the physicochemical properties are suitable for characterizing the distribution of PAHs in soil, moss and reindeer dung. [Copyright &y& Elsevier]- Published
