| Outline of Final Research Achievements |
The seawater bubbled with exhaust gas emitted from marine diesel engine using a future-generation fuel (new fuel), a 70 % heavy fuel oil with 30% dimethylether, or a traditional heavy fuel oil (C fuel oil) was subjected for ecotoxicity assay and chemical analyses. The seawater bubbled with the gas using C fuel oil indicated higher toxicity on algal growth than that using new fuel. Toxic substances to inhibit algal growth were adsorbed on the particles whose diameter ranging from 0.1 to 1 μm in the seawater. The total amount of polycyclic aromatic hydrocarbons (PAHs) adsorbed on the particles in the seawater bubbled with the gas using new fuel was higher than that using C fuel oil. Carcinogenic PAHs were adsorbed on the particles whose diameter ranging from 0.1 to 1 μm in the seawater bubbled with the gas using C fuel oil, but they were not detected in the seawater with the gas using future-generation fuel.
