• Three- to seven-ring parent and alkylated polynuclear aromatic hydrocarbons (PAHs) are determined in 20 deep sea surface sediments collected along a 175°E transect from 48°N to 15°S. The latitudinal distributions of PAHs except for perylene and retene show that they are low in the low latitudes (15°S−24°N) but remarkably increase from 27°N to 48°N. Concentrations of these PAHs at 48°N are 1−3 orders of magnitude higher than those of the lower latitudes. Similar latitudinal patterns of these PAHs suggest that they were transported as mixtures attached to some aerosol particles but not free forms.
