Secular changes of PCB concentration accumulated in organs and tissues of Japanese from 1974 to 1989.
The concentration and component types of PCB in adult human liver and fat tissue (64 samples) from forensic autopsy cases of Osaka Prefecture in 1989 were measured for comparison with the data for the same organ and tissue during the period from 1974 to 1984. The mean values of PCB levels in 1989 were 0.06 microgram/g (whole base) in the liver and 2.20 micrograms/g (fat base) in the fat tissue. These concentrations both were the same as those observed for the 15-year period. The percentages of the 5,6-chlorinated compound of PCB in the liver and fat tissue were lower but those of the 7-chlorinated compound were 15-20% higher.
