Abstract

Polycyclic aromatic hydrocarbons (PAH: Phenanthrene+Anthracene, Fluoranthene, Pyrene, Chrysene+Triphenylene+Benzophenanthrene, Benzofluoranthenes, Benzo(a)pyrene +Benzo(e)pyrene and perylene) were measured in 19 surface sediment samples from Tokyo Bay. The range of total PAH concentatrations is 264-1489 ng/g-dry sediment. PAH concentrations are lower for the southeastern area of the bay and higher for the western area. Sediment samples taken near the mouths of Rivers Sumidagawa, Arakawa and Nakagawa showed high PAH concentrations, suggesting that rivers are an important route for supplying PAH to the bay sediments. Distance indices were calculated to examine the similarity among samples in terms of the relative abundance of individual PAH. Samples except for 3 samples were classified into two clusters by cluster analysis of distance indices. The difference of two clusters seems to reflect the difference in the residence time of PAH in the bay water.
