Abstract: Water, Sediment, moss, penguin-dropping and organism samples were collected from Fildes Peninsula to investigate the distribution and environmental behavior of sixteen polycyclic aromatic hydrocarbons. The results indicated that the total PAHs concentrations in water, sediment, moss, penguin-dropping and organisms were 34.9~346 ng/L (mean=184), 68.9~374 ng/g (mean=188), 122~894 ng/g (mean=251), 197~293 ng/g (mean=245) and 137~443 ng/g (mean=265), respectively. Compared with the other regions, the proportions of 2+3 ring PAHs to the total PAHs were higher than 0.5 whereas the proportions of 5 + 6 ring PAHs was below 0.2 in all compartments, which implied the atmospheric transfer was the main source of PAHs. Significant log/log-linear relationships between the soil/moss quotient (QSM) and the sub-cooled liquid vapor pressure (p°L) and octanol-air partition coefficient (KOA) were observed. Also the similar significant log/log-linear relationships between octanol-water partition coefficient (KOW) the bitoa/water quotient (QOW) and the penguin-organism/penguin-dropping quotient (QPD) were observed. The results indicated that the concentration rations between different media could be seen as a “mirror image” of distribution behaviors of PAHs in the remote Polar Regions.
