Gas Chromatograph/mass spectrometric survey analyses were performed on the air, seawater, sea sediment and seaweed samples from several urban areas of Japan. More than 400 compounds, including 49 halogenated compounds, were identified. In addition to common contaminants (n-alkane, polycyclic aromatic hydrocarbons, chlordanes, chlorobenzenes, triclosan, trichloroethylene, etc.), some novel contaminants, such as bromodichloroanilines and chlorodibromoanilines, were found in sediment and seaweed samples. The compositions of aromatic hydrocarbons in sediments showed marked regional difference. Alkylbenzenes (C<SUB>9</SUB>-C<SUB>14</SUB>) were found in Tokyo Bay, owing to domestic waste water contamination, while no alkylbenzenes but a large number of polycyclic aromatic hydrocarbons found in Dokai Bay. Thus, the composition of aromatic hydrocarbons in sediment may represent the regional characteristics on pollution.
