The concentration of polycyclic aromatic hydrocarbons (PAHs) and the toxicity to marine bacteria (Vibrio fischeri) were measured for the organic solvent extracts of sea sediments collected from an urban watershed area (Hiroshima Bay) of Japan and compared with the concentrations and toxicity of atmospheric particulate matters. Among atmospheric particulate matters, the PAHs concentration was highest in FPM collected during cold seasons. The concentrations of sea sediments were 0.01-0.001 times those of atmospheric particulate matters. 1/EC50 was 1-10 L g-1 PM for atmospheric particulate matters and 0.1-1 L g-1 dry solids for sea sediments. These results imply that toxic substances from atmospheric PM are diluted several tens or hundreds times in sea sediments. The ratio of the 1/EC50 to PAHs concentration ((1/EC50)/16PAHs) was stable for all sea sediments (0.1-1 L μg-1 16PAHs) and was the same in the order of the magnitude as that of FPM and CPM. The ratio of sediments collected from the west was more similar to that of CPM while that of the east was to FPM, possibly because of hydraulic differences among water bodies. The PAHs concentration pattern analyses (principal component analysis and isomer ratio analysis) were conducted and from the results. PAHs pattern of sea sediments was fairly different from that of FPM and CPM. Comparison to previously conducted PAHs analyses suggested that biomass burning residues comprised a major portion of these other sources. |
