Consideration on oil pollution to particle size of bottom sediments.

Consideration on oil pollution to particle size of bottom sediments.

The extent of oil pollution of bottom sediments depends greatly on their particle size. Generally oil concentration in muddy sediment tends to be higher than that in sandy sediment. As the result of experiments, it is found that most of oil in bottom sediment is absorbed in the fraction of silt and clay. Then we proposed the following value to correct the influence of particle size ; Analyzed value The corrected value＝Analyzed value /Mud content ×100 From the distribution of the corrected value of bottom sediments of Tokyo Bay, it is clear that excessive oil pollution over 1000 ppm extends to the open sea along the Trough.
