Abstract

On January 2, 1997, the Nakhodka, a Russian tanker loaded with 19,000 kl of C-type heavy oil, was broken up into sections and submerged off Oki Island, Shimane Prefecture, Japan, which yielded serious environmental problems throughout the shores of Hokuriku district. We report the characterization of C-type heavy oil, 20 years after the Nakhodka oil spill accident, based on observations in the field on January 18 in 2017. We studied the microstructure, mineralogy, chemical composition, and radioactivity associated with the microorganisms in soils contaminated with C-type heavy oil with fishing net and rope, using a combination of microtechniques, analytical data. The fish gears that had buried in a beach show high concentration of Na, P, S, Cl, Sr, and Pb, which is predominantly indigenous to the spilled C-type heavy oil, whereas Na, Al, Si, P, S, Ca, Fe, and Sr are detected on the fin whale skeletons that has stored in a museum after being collected. X-ray powder diffraction (XRD) of the contaminated soils after 20 years showed consistent with paraffin, graphite and calcite. Many kinds of hydrocarbon-degrading bacteria, such as Micrococcus bacillus and filamentous fungus were found in oilcontaminated soils after 20 years in the coast of Wajima, Ishikawa Prefecture, Japan. To date, no report has described the results of electron microscopy observations and in this research; such observations are introduced, including the real-life occurrence of bioremediation by hydrocarbon-degrading bacteria, graphite, and paraffin wax. These observations could lead to simple methods of removing C-type heavy oil from the environment.
