| Research Abstract |
Environmental hazard of the particulate matters (PM) in ship exhaust gas emitted with next generation fuels was evaluated using chemical analyses and ecotoxicity testing. The PM emission, the ecotoxicity, and the mutagenicity of the PM generated from Jatropha oil were lower than the ones from marine diesel oil (MDO: heavy oil A) and heavy fuel oil (HFO: heavy oil C). The PM emission and the ecotoxicity/mutagenicity of the PM generated from the 70 % heavy oils mixed with 30 % dimethyl ether (DME) did not quantitatively decreased in comparison with the ones from MDO or HFO. New compounds produced from heavy oils and DME might explain non-reduction in the toxicity.
