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 finwhale skeletons that has stored in amuseumafter 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 oil-
contaminated 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.
