QUANTITATION OF SULFUR-CONTAINING OIL COMPOUNDS AND POLYCHLORINATED BIPHENYLS (PCBS) IN SEDIMENTS FROM WATERS OF THE OSAKA PORT AREA

Sediments were periodically collected from the waters of the Osaka Port area during the period of 1970 to 1977 and analyzed for oil pollutants and polychlorobiphenyls (PCBs). Sulfur-containing oil components and PCBs were most noticeable in the vicinity of the mouth of the Shirinashi River and they originated from discharges and/or dumping into the river. Analyses indicated that the sulfur-containing materials were derived from a Class C heavy oil, and were present in the sediments in a range of 0.49 to 7.5 ppm (dry basis). PCB residues ranged from 0.45 to 4.0 ppm. © 1979 Springer-Verlag New York Inc.
